About Me:
My name is Tricia (A.k.A Patricia).... I am 17 years old. I go to Olathe North high school. I am a Junior. I use to be afraid of snakes but now i think that they are the coolest animals. on this earth. I am Hispanic even though i look white. I have a brother and a sister my brother is older than me by a year and a half and my sister is 6 years younger than me. I love to be outside, I cant stand to be inside all the time.I hope to go to college in California with one of my best friends. I hope to one day become a vet or a pediatrician.

Survival of the fittest in snakes is my topic.
What is Survival of the fittest?
Natural selection conceived of as a struggle for life in which only those organisms best adapted to existing conditions are able to survive and reproduce.
~The Black Mamba~
There are many different kinds of snakes. One is the most feared and the deadliest in Africa is The black mamba. This snake lives in south Africa. The black mamba is not really black.It has a grayish tent. It has a head shaped like a coffin, and has brownish scales along its back. It gets its name from the ink colored mouth it has. This snake can grow up to 14 feet in length, and travel at speeds of up to 12 mph. The black mamba can strike up to 4-6 feet away. The snakes Venom is Neurotoxin which affects the nerves. Most victims die because the venom is so strong that it stops all messages to the nerves from the brain and most victims die of suffocation. When there was no cure for snake bites the chance of you dieing from the bite was 100%. Why Is this snake so feared in Africa? There are many stories about this snake chasing people for miles, Striking at you because they see you and slithering into your house, and killing everyone inside. so not many people want to go near them or see them. The black mamba survives because the venom of this snake is so deadly that just 2 drops of this snakes Venom can kill a human.
~Eastern hog-nosed snake~
The eastern Hog nosed snake Has a upturned snout it helps them to dig under loose soil. The western hog nose has the ability to act like a rattle snake which makes it seem bigger and more dangerous than it really is. The hog nose are active during the day. They bask in the open. When the hog nose feels that it is endanger it will flip on its back and act dead. In the winter time the hog nose will burrow under the soil and some times steal other animals burrows such as the gofer and eat the family and make the burrow bigger for its new home. The snake Survives because it has the actions of a Rattle snake. Because this snake is smart it will survive and make more babies.
~Western Diamond Back Rattle Snake~
The Diamond back snake is one of my favorite snakes. The Diamond back Lives in the desert and can go for several days without water. It get its water supply from the blood of the victim. The Diamond back also recycle the water from its Urine. So i poops out crystal like substance instead of liquid. The Diamond back can grow up seven feet in length. The colors ranges from brown to gray to pinkish, depending on the shade of its habitat.Its head is distinguished by two dark stripes, one on each side of its face, which run diagonally, like Zorro’s mask, from its eyes back to its jaws. Because this snake is so In line with its habitat it can survive and will live on to reproduce.

Adaptive Radiation
About Me: My name is Ashley. I am 16, and a junior at Olathe North. I play both clarinet and saxophone in the band. Music is my passion. My taste in music is differed. One minute I can be listening to Timbaland the next I will be listening to the Eagles "Hotel California." I am an only child and really wish I wasn't. Everyone always says that you are soooooooooo lucky but the truth is that I wish I had a sibling. The bad thing about being an only child is that you are constantly in the spotlight. Another bad thing about being an only child is that it is harder to communicate with people your own age. Talking to adults is still easier than talking to kids. I am a major sports fanatic. I have been to all the football game this year! GO EAGLES!!! I have been playing soccer since second grade and absolutely love it!
Adaptive Radiation as defined by the dictionary is," evolutionary diversification of a generalized ancestral form with production of adaptively specialized forms." Or for all the rest of us that speak English not Scientific mumbo jumbo it means species that undergo many changes over time. Another way of saying it is rapid specitation. The best example of this is us, because humans we are one of the most evolved species on this planet.
There are lots of examples of adaptive radiation in humans. The fact that we can walk on two legs is a adaption. Our hands have adapted to do specific tasks such as picking up things, the ability to squeeze things, and many other advanced things. Another example of adaptive radiation in humans is the advancement of melanin. Melanin is another name for skin pigment. There are many questions that can be asked for people to understand how melanin helps people survive in certain environmental areas. Would a person with black skin survive in Russia? Probably not! Would a white person survive for a long time in Africa? Probably not! This is why white people are usually in cooler places and why black people are in hotter areas and not the extremely cold places. That is how melanin is a adaptive feature of humans. Another example going along with the human body is the fact that our bodies gives an indication of the temperature in a certain climates. This is why we feel cold when snow is on the ground. This usually is helpful because it is an early warning sign for humans to get inside and start the fireplace. Many others animals, such as snakes do not have this luxury. Snakes can stay on a heated rock and not know it is hot and burn themselves. The last example I am going to give you about adaptive radiation in humans is the fact that humans have offspring, children, that are broader and smaller live in colder places while children in hotter places are thinner and taller humans. This is probably why there is so many people that are good at track in Kenya.
One the most asked questions about adaptive radiation is how is it caused? One of the causes of adaptive radiation is isolated ecosystems. Or in other words a place that is so separated there are not many species around. A type of isolated ecosystem that works well for adaptive radiation is mountain areas. It makes sense because not a lot of animals can survive those types of areas or even want to go up to those mountain areas. One of the examples of adaptive radiation is marsupials because they were isolated geographically, by a continent. This continent of course being Australia.
The main force driving animals is to stay alive and to make babies. The adaptive features that is best suited to their environment survive, while those animals that aren't suited to their environment will not survive. This is natural selection at its best. Mammals come from the same common ancestor. These common ancestors branch out with subspecies and become more and more diverse. When these subspecies become diverse they can no longer interbreed. Like a donkey and a horse. This happens because the animals become more and more separated from their common ancestor.The result of this is actually a good thing because it shows that animals are reproducing with certain heredity traits that are getting passed down to their offspring. Like the beginning of this paragraph the animal best suited survive the least suited die.
The best example of this of course is Darwin's finches. Darwin was a scientist that traveled to the Galapagos Islands. When observing the island he found these finches that looked the same but they really weren't. Each one of these finches became there own subspecies. The original finch was a seed finch these seed finches had babies and the hereditary traits in their gene pool to create different kinds of finches such as tool using finch, grubs, buds/fruit, leaves, and insect finch. These all came from the common ancestor: the seed finch.
The phrase that goes along with Darwin's finches is form is best suited for their function. The grub finch for example needs a long skinny beak to get into tigher places, such as logs. The Buds/Fruit finch needs a bigger stronger curved beak in order to crunch the fruit with their beak. The Buds/Fruit finch would also not want to have a smaller beak because then there would be no room to put the big fruit in its mouth. The tool using finch needs a bigger beak in order to hold the tool in its mouth. The insect finch also needs a small beak like the grubs finch in order to get its beak into to smaller places to get food. The Leaves finch has a medium sized beak because it really doesn't need a small beak or a big beak to get leaves. With this discovery of the finches the idea of evolution was starting to become more and more possible. There is one thing that the creationists and the evolutionists actually agree on that humans, like Darwin's finches, came from a common ancestor.
Here is an overview of the topics discussed. Adaptive Radiation is the basically the concept of speciatation. Creating subspecies from a common ancestor. Adaptive Radiation can happen many ways. One of these ways is an isolated ecosystems. An example of this is Australia. Another example of how adaptive radiation is after a mass extinction. There are many examples of adaptive radiation one of these being Darwin's finches. The phrase that goes along most with Darwin's finches is form follows function. This is shown from the seed finch, the common ancestor, in its gene pool creating new species of finches. These new species of finches is Buds/Fruit, Grubs, Tool Using, Insects, and Leaves finch. Adaptive Radiation is important to understand because it shows that Evolutionist and Creationist have a common link of understanding: a common ancestor.

Camouflage and Mimicry
Name: Lindsey
About Me: I am in love with Keith Urban and he is my future husband. I am eighteen and I will be going to K-State University next year to study Veterinary Medicine. I went to Mahaffie Elementary School and after that Santa Fe Trail Junior High.
I drive a red Honda Civic and it's a manual transmission. I played softball for North for three years and volleyball freshman year for SFT.
********************Camouflage*******************
Camouflage is an animals ability to visibly blend in with it's environment. Camouflage is a form of deception and allows animals to hide from their predators safely. Some animals can do this by simply by blending into their environment, while others are able to actually change their color so they can match any surrounding environment.
-Chameleons-
There are eighty species of chameleons whom are all highly aggressive and brightly colored. They have a ridge on the top of their heads and can get as tall as two inches by the time the animal is mature. Their eyes are also interesting because they are able to move separately and can look in two directions at once. This allows the animal to follow prey without moving its head.
Chameleons reside in the trees and have special hands that allow them to grasp the branch of the tree so they don't fall off. Their hands are similar to a humans because they contain fingers, but also differ because the fingers are fused together at the middle. Besides having these fingers to keep them from falling off the tree, a chameleon also has a prehensile tail that they can use to hold on and keep their balance.
When it comes to color changes, the chameleon is the best. A chameleon not only changes color to blend into its surroundings, it also does this to show its emotional state. Most of the time green and brown signify a chameleon at rest, and a more brightly colored chameleon is usually frightened or defending its territory. They also turn dark colors when they are threatened and playing dead.
-American Toad-
The American Toad is a medium sized toad and can grow to be 3.5 inches long. They have spots and contain up to two warts on them. They can also secrete a type of mild poison that can irritate human skin.
Out of all the types of toads out there, the American Toad has a good way of camouflaging it self and its eggs. The toad itself can be several different colors, ranging from brown to red to olive and gray. All of these colors help the toad blend in with its surroundings, such as trees and leaves.
Besides camouflaging itself, the American Toad also lays special eggs that blend in with the water so they are less susceptible to being eaten. When being looked at from the top, the eggs are a dark almost black color that allows them to blend in with the bottom of the pond; from the bottom, the eggs are a whitish color so they are not in plain sight of the fish below.
-CHEETAH-
The cheetah is the fastest animal on land. They can run up to 78 mph, which comes in handy when they are hunting. They weigh any where from 90 to 140 pounds and can be up to 55 inches long. Cheetahs also have large nostrils, hearts, and lungs that allow them to take in larger amounts of oxygen while running.
Even though these animals are able to run very fast, they can only maintain that speed for 500 yards, so while they are waiting for prey to get closer they need to be unseen. They are able to do this because of their specially colored coat. They are a base color of tan and on top of that are black round spots. This coloration allows them to blend in with the tall grasses that they lay in while waiting for prey to come along.
***********************Mimicry********************
Mimicry is a situation in which an animal acts like another in order to scare predators away.
-Walking Sticks-
There are over 3,000 different types of walking sticks which are mostly found in tropical regions all over the world. They are very laid back insects and spend most of their time hanging from leaves and branches in trees. When they are not hanging around, they are probably eating. They usually eat berries, cherries, and certain types of leaves.
Walking sticks use mimicry and are one of the best at it. A walking stick mimics a stick so other animals cannot tell that it is actually an insect. It is very hard to tell a walking stick from a real stick, which is a pain for someone who is looking for one, but extremely good for the insect itself.
When a walking stick loses a leg or gets hurt it has the ability to regenerate the limb that it lost. After the insect has molted, or shedded, its skin a couple times the lost limb grows back. The walking stick also uses its molt as food after it has been shedded. It serves as a good source of food and goes unwasted.
-Milk Snake-
Milk snakes are found in many different countries and can grow 24 to 36 inches long. They are a species of the king snake and there are 25 different subspecies of milk snakes, but they all look very different.
Milk snakes are multicolored and consist of red, yellow, and black. Just by catching a glimpse of them so might think them to be the highly venomous Coral Snake. The reason for the Milk snake being these particular colors is for that reason exactly.
They are a small snake and don't really have another defense, so they take advantage of their color and use it to drive potential predators away.

Selective Breeding
about me My name is Brazille. I am a Junior and attend Olathe North High School. I make pretty good grades. I can't wait until I'm a senior and out of school, but what can i do? I have to finish this like a champ! I am 17. My birthday is July 29th. I am a Leo. Next year I will get through my whole senior year being 18 years old. I am what you would call "creative", or "weired"....what ever you want to call me; i just know I'm unique! I have a boyfriend and I am very much in love. I enjoy school and all the activities that come along with it. Basketball is o.k, but i absolutely love running track. After I graduate I plan on being a very successful young lady!!!! Thanks and go ahead and check out the rest of mine and my team members blogs!!!
Natural Selection: Charles Darwin was a biologist from England and he developed a theory that would imply that all species derived from common ancestors through the process called natural selection. Natural selection is the process by which favorable traits that are in heritable become more common in successive generations of a population of reproducing organisms, and unfavorable traits that are heritable become less common. Natural selection is considered to be the biggest factor resulting in the diversity of species and their genes. It(Natural Selection) is one of the cornerstones of modern biology.
Charles Darwin: Born February 12, 1809 and died April 19 1882. English naturalist Darwin; was the most famous for coming up with the theory of evolution. This theory states that all types of living organisms came from a common ancestor. He states that some organisms are better adapted because of normal differences brought about by changes in the genes also known as mutations. Some differences might make an organism more successful it could have a chance at better survival and could pass on its genes in the future generations to come. Anything that has a lower survival rate will be less likely to be passed on and will sooner or later die off.
Moth Example: An example of evolution resulting selective breeding the "peppered moths were discovered living near England's industrial cites. The insects had different varieties and varied from shades from light to
dark. In the time of the 19th century nasty, dirty, sooty, dark, polluted smoke from coal burning factories with furnaces that killed the lichen off the trees and turned the bark darker. Therefore the dark peppered moths blended in better with the dark trees and didn't get eaten by the birds simply because they weren't visible. So the darker ones lived on and reproduced even more the environment favored dark moths. Once things were cleaned and back to there normal and light colors the light colored moths were in favor to the environment. Researchers say that this study in partially complete; there might have been other factors of natural selection involved.
Finch Example: Darwin's Finches is a good and also well known example of the way genes adapting in order to survive long term to produce their offspring. Darwin came to realize that any population consist of individuals that are slightly different from another. some of those individuals have it well because they have the variation that gives them the advantage of staying alive longer than the others and long enough to successfully reproduce and pass their traits frequently to the next generations. The trait become common and therefore the population evolves. Darwin seen that the size of the beak had to do with the Finches diet based on different foods. In order to survive the birds had to move to different environments where they had to adapt to different conditions. The change was necessary in order for them to eat and reproduce.
