Welcome!

This website aims to tell you nearly everything you need (and may ever want) to know about convergent evolution. It allows y ou to explore the way that similar adaptive solutions have repeatedly evolved from unrelated starting points on the tree of life, as though following a metaphorical ‘map’.


We have identified hundreds of examples of convergence, so if you want to learn about convergence in sex (e.g. love-darts), eyes (e.g. camera-eyes in jellyfish), agriculture (e.g. in ants) or gliding (e.g. in lizards and mammals) then this is your best port of call.

What could be more different from us than the alien-like octopus? Hold on. Look it in the eye and think again.

“Specializations of the Chorioallantoic Placenta in the Brazilian Scincid Lizard, Mabuya heathi: A New Placental Morphotype for Reptiles”

D.G. Blackburn & L.J. Vitt 2002, Journal of Morphology, volume 254, pages 121-131.

Female skinks of the genus Mabuya provide almost all the nutrients their developing embryos need through a placental structure. The Brazilian species Mabuya heathi exhibits an extreme placentation type with several specialisations that converge on those of the eutherian mammal placenta.
