Darwin amassed evidence in support of evolution, provided the basis of a theory explaining the evidence, and most importantly, came up with a mechanism driving the evolution he observed.I tend to disagree, the only thing Darwin discovered was a diverse set of animals, fish and plants that in some ways had similar characteristics. He then speculated\theorized that their origins must have come from the same source.
There is a vast body of evidence from numerous scientific disciplines. The existence of this body of work is denied by many creationists. I think this is largely out of ignorance, but there are other reasons that it is denied.
I do not understand what you mean by linear here.His thinking is linear which was the flawed point of view.
Seriously?This can be easily debunked by asking one very simple question:
If humans evolved from monkeys, then why are there still monkeys living in the trees today while we are building skyscrapers instead?
-
Humans evolved from an ape or ape-like ancestor that we have in common with other species of ape, including chimpanzees and bonobos.
Much further back, we share a history with monkeys.
In essence, you are claiming that in order for evolution to occur, any ancestral species must go extinct in order for the descendants to exist. The co-existence of putative derived and ancestral groups, following this logic, refutes the theory describing that existence.
This does not make any sense in light of the theory, the evidence or positions in science. There is no reason that ancestral species must go extinct when daughter species evolve. The theory does not demand, hint or imply this.
Using your logic and extending it to existing species, penguins cannot be birds, even though they share all the characteristics that define birds. Ostriches could not be birds either, since they are large and do not fly.
It is not a surprise that related species share commonalities and also have features unique to them. We only recently began creating skyscrapers and the existence of skyscrapers today does not refute our more primitive construction efforts of the past. Using that as a criteria to determine relationships leads to questions like '20,000 years ago, we did not build skyscrapers, were we then related to monkeys?'.
Species are optimized by evolution for the environments in which they exist. We have evolved a large brain and a conscious mind that allows us to do things that other species cannot or do not. This is a question of the degree of difference in our intelligence and not evidence or criteria that defines a relationship. Monkeys and apes have larger brains than most other species. They use tools. They have complex behaviors. They can learn. We just have traits that allow us to take that further. This does not mean that we are not related.
This is a very old and much refuted notion that you repeat here. You have a fundamental misunderstanding of evolution and biology. I think if you look at the evidence and theory carefully, you will see how silly the idea is.
