A species is a group of organisms that can interbreed and produce fertile offspring under natural conditions. They share common characteristics and genetic similarities, distinguishing them from other groups.
5 Must Know Facts For Your Next Test
Speciation occurs when populations of a species become isolated and evolve independently.
The biological species concept defines species based on reproductive isolation.
Gene flow between populations can prevent speciation by homogenizing genetic differences.
Adaptive radiation is a process where one species gives rise to multiple new species, often due to different environmental niches.
Phylogenetic trees are used to illustrate the evolutionary relationships between different species.
