brainer?.........what are some types of evidence supporting evolution?

Answer 1

The most obvioius example are the fossils found in different layers of rock. Each layer, scientists have determined, was on the surface of the planet at different eras of the earth's development. the oldest layer is deeper within the earth and newer layers are piled above. Scientist have found fossilized bones in the various layers and they can build a timeline describing the changes various species have made throughout the millenia.

The next, and most exciting evidence is what scientists are compiling by studying DNA. they have already established years ago that the chimp is a very close relative to the human.

Also there is the fact that the human has gotten taller, even in the last 100 years. Even in the last 40years! In the US in the 1960s, a 5'5" woman was considered tall. not by today's standards. The human has evolved before our very eyes.

Answer 2

Population's evolve when the genes of that population are altered in some way and the alteration becomes the norm rather than the exception. Most people view evolution on a macro-scale (did humans evolve from apes?), but there is ample evidence at the microscale. You can see examples of this yourself in things like bacterial resistance to antibiotics or pest resistance to agrochemicals. When a modified trait increases the fecundity of an individual, that individual reproduces more and increases the proportion of that gene in the population. This is hard to see in humans because we reproduce so slowly, but easy to see (and test) in organisms that reproduce quickly.

Answer 3

The diversity of life on Earth
Genetics and molecular genetics
The fossil record
