Evolution... 10Points 4 BA + Only Serious Answers Wanted!?

Question

What is the main evidence for evolution?

Oh and please don't just copy and paste from another website.. I'd like it in you own words.. That'd really help!

Only serious answers please and 10points for best answer!

Thanks in advance! =]

Answer 1

<<What is the main evidence for evolution?>>

There's far too much evidence for any to qualify as "the main evidence".  The entire science of biology presently only makes sense from an evolutionary perspective.  It's the only theory, for example, that accounts for baby koalas being born with vestigial egg-"teeth" on their jaws for helping them work through parchment egg shells that never actually developed.

From among other fields, evidence for evolutionary theory comes from comparative anatomy, genetics, the fossil record, stratigraphy and embryology.  If you want transitional fossils showing the development of mammals from non-mammalian predcessors, then check out /Thrinaxodon/, /Cynognathus/, /Probainognathus/, /Pachygenelus/ and /Morganucodon/.  (Normally, those generic names have to be written in italics.  This system doesn't allow that to be done, thus the back-slashes as substitutes.)

The link is to a website that's in my own words already, seeing as I've written all of it myself (quotations excepted).

If a subject is serious, then it's worth making jokes about it.

Answer 2

protohumans found in asia and the skeletal structures found.

Answer 3

There are several branches of evidence for evolution:

[1] fossil evidence - such as the almost-complete record of the evolution of the horse, the fact that different organisms appear and then disappear at different times through the fossil record (no rabbits in the precambrian era, and no veloceraptors nowadays)

[2] comparative genetics - organisms have genes that are closer in sequence to more closely-related organisms; even "junk DNA" shows evidence of the "relatedness" of organisms

[3] comparative biochemistry - all life-forms use the same 5 nucleotides, and the same 20 amino acids; organisms that are more closely related will have similar biochemical pathways (Old World primates have 3-colour vision, New World primates only have 2-colour vision)

[4] geographical distribution - organisms which are more closely related are often found closer to each other (marsupials in Australia, for example), historical migration patterns, etc.

[5] comparative anatomy - the pentadactyl limb, insect mouthparts, snakes with atavistic hindlimbs, etc.

[6] observed evolution - emergence of antibiotic resistance in bacteria and pesticide resistance in mosquitoes, industrial melanism of the peppered moth, diversification of Cichlid fishes in African lakes; also actual observed speciation events like reproductive isolation of laboratory strains of Drosophila fruitflies, and emergence of the ability to metabolise citrate in a long-term E. coli evolution study.

In all seriousness - there is *far* too much evidence to sensibly list in one answer here. Check the links below for some more evidence.

the different evolving structure of monkeys?
