eohippus

Tanımlar (İngilizce)

1. isim An extinct early Eocene mammal (Hyracotherium leporinum), ancestral to the modern horse.

   “An eohippus may "evolve" into a horse, but when we say that a society of hunters and gatherers evolves into a farming village, we are using the word "evolves" as a metaphor for a process of directional change.”
