Document Summary
Some evidence was available to darwin while some wasn"t. Evidence from various different fields are consistent with evolution and ideas relating to it. Evidence for darwinian evolution would include any sort of evidence that suggests that the lower model [descent with. Modification] is a better explanation for life on earth than the upper model [special creation] Darwin made analogies with artificial selection imposed by humans and natural. He looked at domestic plants and animals [people breeding them for certain traits] The analogy was then that natural selection could work in the same way with ecological conditions/social conditions imposing the selection on the lineages. E. g. dogs = originated from a wolf-like ancestor [for every breed] Somewhere between 15000 or 100 000 years ago, humans started domesticating wolfs: Results are a stunning range of different body forms, physiologies, temperaments, furs, and lifespan. So impressive range of changes in morphology, physiology and etc through artificial selection.
