The theory says that all life evolved from 1 cell. Now we have observed that cells can multiply but the theory collapses because a cell can only multiply itself. For example a whales liver cell can only produce more whale liver cells. It most definitely has not been observed to spawn completely new and different cells. As for mutations that only occurs when information is missing from the DNA. So a mutation cannot introduce new information. Biologists cannot call their practice a science. Physics and chemistry is science. Biology the way it operates on evolution and the big bang is a philosophy. Simply put unless a cell is observed multiplying into new cells then the theory collapses. The theory is also made redundant unless several fossils of an evolutionary man in transition can be found. As for creationists don't get too excited because this does not automatically mean that your theory is correct either
Ok lets simplify things as much as possible then. The theory of evolution claims that all life originated from 1 cell. Has a cell ever been observed to create a totally different cell? Seeing that would have been required to produce such different types of life forms.
Ok you are describing reproduction in animals which is not what im talking about. From what I understand a cell can only multiply itself. This being the case how can all life on earth have originated from only 1 cell? So now some of you are saying that life did not originate from 1 cell. So Richard Dawkins must be incorrect then.
