Examples:
Why aren't there people that can run very very fast?
Or with an eye at the back of their back?
Or a human race like elves, dwarves?
Or a human race that can smell or see extremely well?
Or people that see black & white?

Reference points:
1. No one can claim that having 6 fingers is weak against evolution.
2. All our differences are minor, like color, shape of body parts, minor differences in perception etc.

Based on evolutionary theory humans could be related to simians in many ways. If this is true why is it that when a human does not cut his/her head hair, it will continue to grow? Why is it that monkeys do not need to cut their hair? It seems that their hair has a determinate final length.

How did 'sex' and 'gender' evolve? How infinitely improbable is it that two creatures randomly envolved into other creatures that are made for each other?

Darwin's theory of evolution suggests that we descend from apes. While no strong evidence has been found, one may think of "backward compatibility", i.e. why organ transplant doesn't succeed from apes to men (which would be a simple corollary of the theory of evolution) to build a counter example and even strengthen the theory of evolution (from men to apes this time).

Imagine that you have been chosen as the biologist for thedesign team for a self-contained habitat, Space Station ECOS, to be assembled in orbit. It will be stocked with organisms you choose to form a self-sustaining ecosystem that will support you and five other people for two years. Describe the main functions you expect the organism to perform. List the types of organisms you would select, and explain why you chose them.

Please help!

Thank you very much!

a research biologist but I want some feedback from people in the career to help me decide what type of job I'm really looking for and what field I should focus on... I have this idea in my head and I want to know how close my idea is to the reality of actually being a biologist
Biology is definitely my thing... all facets of life fascinate me, from the life of a fungus to life in other parts of the universe. I'm starting college this fall with a major in Biology, but I want to know where I should go from there and what I can to with a degree in Biology.

Any (serious) answers are greatly appreciated!

Just to state, I am not a creationist. I am a former creationist that has since come to their sense, and am now very curious about evolution. Evolution only barely makes sense to me, but I'm ready to learn. Please refer to this video:

http://video.google.com/videoplay?docid=7066578568747223192&q=cute&hl=en
(It's about the Pika, the incentive to watch is that it's cute)

What I don't understand is how the Pika knows what is poisoness, and what is not. Also, how does Pika know that the poison will preserve the plants into the winter? I don't understand how the plant and animal correspond to each other perfectly (natural selection of course, but I want something more specific). In the past, I would only have said 'they were designed for each other', but I am now seeking a better answear.

Sometimes in the summer, outside, I hear something I can only describe as a loud buzz. It starts by crescendoing into a loud continuous buzz until it stops after about 5 or 6 seconds. Can anyone tell me what animal or insect generates this noise?
