Chimpanzees
They are not the same species but they belong to the genus Annona. They both are distantly related.
They are descended from extinct species, but are megapodes, distantly related to pheasants, and most particularly closley related to cracids. They are in the family of galliformes.
Well, the common housefly,l the bluebottle fly, and more distantly the deer fly are all related to the horsefly.
These four species are distantly related and share a common ancestor.
Comparative Embryology
It's called convergent evolution
Adaptive convergence is a form of evolution in which two unrelated (or distantly related) species evolve very similar forms due to similar selective pressures.
If you look at the gene sequences of a species, you can see a clear homology among the same species. Distantly related species wont have similarity at DNA level. Hence by knowing the molecular level information one can predict the evolution of a species.
Related species have similar embryos.
