Well I am just beginning to learn about evolution. It fascinates me and I have a few questions. Why have we begun to loose hair? And turn in to the current species we are now. How would more hair hinder us? Maybe mating choices were influenced by how much or how little an animal had? And were the dinosaurs are ancestors. Or are they ancestors of our ancestor. For some reason I just realized that is probably true haha. I just proposed the question to myself a few minutes ago without thinking.

And my last question is. What are some books I should read to study evolution. I am a fan of Richard Dawkins would you recommend his older books. Are they more about evolution then atheism I am not really sure. Thanks for taking time to answer.

Hi all, I was hoping you could help me solve this question. I’m 19 years old and recently had another growth spurt 8 months ago in my knees where I grew an inch in a week and have grown 3 more inches since, but during it I was eating a lot of soy bread, and I was wondering if the phytoestrogens in the soy bread might have caused the growth spurt leading to a premature closure of the growth plates in my knees and thus stunting my growth, or if I was just genetically programmed to have a late growth spurt at this age?
I ask this because I read up that estrogen and testosterone convert to estradiol, which is the hormone responsible for the growth plates in our bones closing and I was unsure if the phytoestrogens in the soy bread I was eating could do the same thing which might explain my sudden growth spurt, much in the same way that taking steroids can produce a sudden growth spurt but lead to premature closure of the growth plates due to rapid conversion of testosterone into estradiol

Don't give answers like, "use fur to make coats". Try answers that are not widely used or popular, or something that hasn't been done before. Give ideas that may be possible.

One example is, "get a strong thread from a mussel and use it as a rubber".

I have always been taught that a hypothesis must be tested in order to make sure that it is 100% accurate before it becomes a theory. As far as I know, no experiments have been done to prove evolution. Also, why do we call it the "big bang theory" if it's never been recreated and studied? Can anyone shed some light on this subject for me?

originally, i had wanted to major somewhere in astronomy but i noticed that i didn't really like the math that's involved with it. the concept of astronomy is amazing; i love it. however, it requires a great deal of physics and calculus which im not entirely sure i want to do for the rest of my life. i recently looked into marine biology, but have many questions about it. can an actual marine biologist tell me what's a typical day for him/her like and how much the career pays on average? any other information is appreciated! thanks!
