Proteins extracted from fragments of prehistoric eggshell found in the Australian sands confirm that the continent’s earliest humans consumed the eggs of a two-metre tall bird that disappeared into extinction over 47,000 years ago.
Burn marks discovered on scraps of ancient shell several years ago suggested the first Australians cooked and ate large eggs from a long-extinct bird – leading to fierce debate over the species that laid them.
Now, an international team led by scientists from the universities of Cambridge and Turin have placed the animal on the evolutionary tree by comparing the protein sequences from powdered egg fossils to those encoded in the genomes of living avian species.
Humans were hard on charismatic megafauna on the North American continent as well. Over-hunting to extinction. Mammoths are one NA example.
