The surface and cave forms of the Mexican tetra have proven powerful subjects for scientists studying evolution. [28] When the surface-dwelling ancestors of current cave populations entered the subterranean environment, the change in ecological conditions rendered their phenotype—which included many biological functions dependent on the presence of light—subject to natural selection and ...
The totoaba or totuava (Totoaba macdonaldi) is a species of marine fish endemic to the Gulf of California in Mexico. It is the largest member of the drum family Sciaenidae [4] and is the only extant species in the genus Totoaba.

Evolutionary theory says all animals that are walking on land actually evolved from sea-dwelling creatures at some point in the ancient past. To study this further, scientists from McGill ...
