Genetics & Evolution: Speciation 🦋 GCSE Biology Learning & Revision
Manage episode 482340340 series 3139280
In this episode, we discuss speciation.
Speciation, the development of new species, occurs when populations of the same species become geographically isolated.
Over time, genetic variation within these separated groups, coupled with natural selection acting differently on each due to environmental pressures, results in genetic divergence.
Eventually, these populations become so genetically distinct that they can no longer interbreed and produce fertile offspring, thus forming two distinct species.
