An excerpt from an OUPblog article published on 7th July 2016, written by the Oxford Reference marketing team.
'Mammals are defined as warm-blooded vertebrates that are distinguished by the possession of hair or fur, of which the females secrete milk for the nourishment of their young, and typically birth live young (except five known species, including the duck-billed platypus). Small mammals evolved from reptiles about 200 million years ago and have diversified rapidly after the extinction of dinosaurs, but they’ve been roaming the planet for an incredibly short amount of time compared to the other classes of animals.
It is only in the last 30,000 years our species (Homo sapiens) have inhabited the world. Did we outsmart our mammalian cohabitants, or did we pick up any of their characteristics in order to survive? Can these be traced back in our personalities today?'
