Divergent evolution occurs when two or more biological characteristics have a common
evolutionary origin but have diverged over evolutionary time. This is also known as
adaptation or adaptive evolution. These characters can be observable structures from different species or they can be
molecular entities, such as
genes or pathways. This is a kind of relationship observed in
evolutionary biology.
