just a quick question, in terms of evolution, what do you think we have to know for the DAT

Everything, the entire course of evolution throughout the existence of the universe. Even the mass plutonium quantum quark array must be known...you need to understand how quarks slowly evolved into their present day fundamental properties. You need to understand how we came from monkeys.

Awesome, I'll just get right on that...after I get done researching the sea urchin, of course.

know genetic drift, genetic flow, convergent/divergent/directional/etc evolution...and know the diff between lamarch and darwin...just some baisic stuff

Okay guys, please don't make a mockery of my OP 🙁

I was just curious, that's all - because evolutionary biology is more historical, and the questions that came from my bio 2 exam where also mainly historical in nature.

So far, I can only think of Taxonomy, Population genetics; Hardy-Weinburg, cladograms maybe (monophyletic), homologous structures vs anaologous structures. Anything else?

Oh, thanks! I just made a post, but i should have waited longer for your response 🙂

Can I ask you a question, xylashllx?

what is the difference between homologous structures and analogous structures,

I know analogous structures is the result of convergent evolution (which means different species evolving in different areas, but under the same enviormental stress), and because of the same enviromental stress have simliar (analogous) structures

However, homologus structures - does it specifically mean similar structures SHARING a common lineage?

Hope this question makes sense, if not, i hope you can clarify the difference/similarities or whatever between homology and analogy

thank!

correct me if i'm wrong, but,

convergent evolution: (see above post)

divergent evolution: a single ancestral species giving rise to two differen species (is that an example of cladogenesis)

directional evolution: the favourable reproductive success of a particular species 'having' a particular trait (and that trait is a quantitative charactar, such as height), which is present in one of the two extremes (favourable reproductive success of darker species for better camoflauge), and the result is more darker individuals in the next generation?

THIS STUFF IS GIVING ME A HEAD ACHE !!!!!!!!!!!!!

Homologous structures are of the same ancestry but serve a seperate function. They can be determined through gene studies. Analogous structures are structures of no related ancestry, yet those which have developed over time to perform similar function. Hope this is right.

homologous structures are of same ancestry but serve a separate function? Is that neccessarily ALWAYS THE CASE, or CAN they serve the same function?

As far as i know (and i'm just another kid posting on the internet), that description is dead on. That's the way i learned it/remember it. Good talk.
