How about you start at the beginning?

So it seems traits get passed on from parents to children. But how?

Oh, chromossomes cleverly hiding in our cells, huh? What else is there?
http://en.wikipedia.org/wiki/Genetics
Genes... nice... and what's in a gene?
http://en.wikipedia.org/wiki/DNA
Oh, DNA.... but that's just a Nucleic acid.
And, sometimes, the sequence gets a mistake or a hundred in and change occurs.
Sometimes, it gets added stuff and new traits appear.
Oh, then you have the fossil record. Tons and tons of bone turned into rock, attesting to past life forms in ever changing patterns, From older marine life, to younger terrestrial plant life, to even younger terrestrial animal life, to even younger avian life and mammalian life.
Go through all those links... those should get you started.
