A mechanism of heredity. Darwin's concept, panspermia, was based on a blending of factors he called gremules that originated with either sex and were in the blood. This was shown to be completely wrong by Mendel's work on particulate inheritance.
The source of genetic variation
There is no proven theory of evolution only the physical evidence of what Chuck Norris has allowed to live.
He proposed a theory that attempts to explain why and the fact of evolution works.It is, so far, the best and most accurate theory that adequately explains why evolution happens.
Genetic variations are produced by mutations and sexual recombination
They thought the evolution of new species is linked to environmental changes
artificial selection
can someone help me please
There is strong evolutionary evidence by people such as Darwin.There is evidence in our biological structures ie: bones and DNA in particular.Although evolution (the theory) is debated there is very strong evidence (look at Darwins books and research)

Darwins theory of evolution :)

Charles Darwin studied birds, medicine, and theory of evolution.
Darwin's observations regarding ostriches led him to the theory of Evolution. For example, when he visited one part of Argentina, he noticed that the ostriches were similar, not the same, to ostriches from another region of Argentina. The fossil record also mimicked this loosely. Thus, Darwin began to look for a viable theory that could answer this. Hence, the theory of Evolution was born, which made the scientific explanation for life as we know it today. I hope this answers your question.
no the theory of evolution is a species becoming more advanced not over populated
