Can you give me awesome evidence of evolution?

So I've been given an assignment for my intro to biology class. I haven't taken science since high school, and im a senior in college and an art history major-so most of this is review/new knowledge. This class is focused on evolution and plant life. While I know of evolution and its theory, I was wondering if you in /softscience have any really cool evidence of evolution.  Vestigial organs are pretty awesome, as is the concept of adaptation to food resources, but I want to be wowed with new information I haven't heard of before.  Can you help me out? I'm not trying to cheat on this assignment, but rather expand my thinking of life/living things. Also, if you have web sources that can give me examples, it would be greatly appreciated.

Richard Lenski watched some populations of E. coli for like 30000 generations, and eventually they developed **a whole new freaking gene** that allowed them to metabolize citrate.

Apes have 48 chromosomes while humans have 46. If a common ancestor had 48, then it's expected that two of them would have merged to allow us to have two less. If that had happened, then we'd expect one of our chromosome to have vestigial centromeres and telomeres. Human chromosome 2 has vestigial centromeres and telomeres, and each half of it is similar to two chimpanzee chromosomes.
