What is 'organic evolution'? How do em brydogical studies provide evidence evolution?

Answer 1

organic evolution is The process by which changes in the genetic composition of populations of organisms occur in response to environmental changes. See adaptation; evolution
The embryology of different vertebrates provide very strong evidence favoring organic evolution. The early embryos of different vertebrates show striking similarities. This indicates common origin and ancestry of different vertebrates. Thus embryological studies provide direct evidence for evolution.
