Homoplasy Definition:

  • Multiple substitutions and convergence at individual positions obscure the estimation of the true evolutionary distances between sequences.

Homoplasy Explanation:

A homoplasy is a shared trait between set of species in separate lineages i.e. that trait does not found in their common ancestor. Often, a homoplasy will occur when same function is performed by different species. It is termed as convergent evolution. The two reasons for homoplasy are selection pressures and genetic drift. For example, the eye that is independently present in many species.
