Describe 5 major lines of evidence that demonstrate that evolution is a fact.?

Answer 1

1. Fossil records
2. Anatomical records (vestigial organs, embryos)
3. Molecular records (DNA, RNA)
4. Convergent and Divergent Evolution (comparing marsupial and placenta mammals)
5. Natural selection (Industrial melanism=peppered moths, Darwin's finches=peaks size) and Artificial selection (domestication=dogs,cats, agriculture=corns, cabbages)

These maybe key evidences suggesting evolution did occur. However I'm not sure if we can use the word "fact". It is to some, but it is not to others. It's debatable and controversial.

Answer 2

1. I woke up this morning and noticed my arms were very much like a chimpanzee's. 2. I went down to the museum and had a look at their "horse evolution" exhibit. I can't tell which of those old models are the ancestors of horses, and which are "also ran" cousins, but the story is fairly compelling. A long time ago, there were no horses, then there were small creatures that were a bit like horses, and then... well, over time, creatures that were more and more horselike. 3. It turns out that it's not just my arms that are like a chimpanzee's. My DNA is too. And, my DNA is more like a chimpanzee's than it is like a more distant relative such a bunny's. 4. I saw a miniature dachshund. I noticed that while it is very wolflike, it isn't a wolf. There are a couple of mutations, and a lot of selection separating a miniature dachshund from its wolf ancestors. This is an example of "intermediate evolution." There is no known mechanism which would prevent intermediate evolution, over a long period of time, from generating speciation events, and indeed, becoming macroevolution.
