The researchers report that hominin teeth, especially molars, became smaller and longer over millennia to accommodate a growing diet of tough grass-like plants known as graminoids and their underground storage organs. They found that the turn toward grasses began about 3.8 million years ago with the distant human relative Australopithecus afarensis (left). About 2.3 million years ago, the early human Homo rudolfensis (center) gained regular access to carbohydrate-rich underground plant organs such as tubers, bulbs, and corms. But this dietary shift outpaced tooth evolution until about 2 million years ago, when species such as Homo ergaster (right) exhibited a spurt of change in tooth size and shape better suited to eating and breaking down cooked plant tissues to derive their nutrients.

How quickly did Abel’s teeth evolve so he could eat meat from his flocks?

[DuncanWaring]

The branching of early hominids leading to modern humans was driven by a diet of (sometimes rancid) meat and fat. That’s why our stomachs are only slightly less acidic than full-time scavengers like buzzards and vultures.

Cows eat grass.

I eat cows.

So I eat grass, in a roundabout sort of way.
