Evolution

In summary: Pilus thing to happen, the two bacteria need to be of the same species, and the pilus needs to be there. And even then, its not very common.In summary, while DNA can get into other bacteria, it usually doesn't result in anything happening between the two species. There is a chance for bacterial sex to occur, but its not very common.

Mutation is any change in DNA, and yes, there are beneficial mutations, there are also lots of mutations that have no effect whatsoever known as "silent" mutations.

There are not as many gaps in evolution as you believe, you simply do not know enough about evolution to judge it. Nothing is science is ever proven, but evolutionary theory remains sound and valid and has not been disproven. I'm not going to get into much of a discussion of a thread that you just ressurected from 3 years ago. There are plenty of things for which we do not know the function, but it would be hard to claim it's useless when we don't really know that. Your judgement of something being too perfect, when indeed, there are plenty of mistakes that happen (mutations), is really not good refutation of a theory.

What is the proof of evolution?

The proof of evolution is a collection of logical evidence that supports the theory of evolution, which states that all living organisms on Earth share a common ancestor and have gradually changed over time through the process of natural selection.

What are some examples of logical evidence for evolution?

Some examples of logical evidence for evolution include the fossil record, comparative anatomy and embryology, DNA and genetic similarities, and observed instances of natural selection in action.

How does the fossil record provide evidence for evolution?

The fossil record shows a progression of different species over time, with simpler organisms appearing in older layers and more complex organisms appearing in more recent layers. This supports the idea of gradual change and common ancestry among species.

What is comparative anatomy and how does it support evolution?

Comparative anatomy is the study of anatomical similarities and differences among different species. It provides evidence for evolution by showing that closely related species share similar anatomical structures, while more distantly related species have more differences. This suggests a common ancestor and gradual changes over time.

How does DNA and genetic similarities support the theory of evolution?

DNA and genetic similarities between different species provide evidence for evolution by showing that closely related species have more similar DNA sequences than distantly related species. This supports the idea of common ancestry and gradual changes over time through genetic mutations.
