The scientific concept of evolution holds that each species on Earth developed from a process of natural selection acting on random genetic mutation.
Obviously there's loads of scientific evidence that supports evolution. But we wanted to understand the main contentions.
First, there are several different varieties of creationists.
A separate theory, called Intelligent Design, does not dispute the definition of evolution as "change over time" or, for the most part, that living things are related by common ancestry. However, this group does believe that the natural world is too complex and diverse to have occurred through random processes.
