In Mellars' view, modern humans spread into western Europe around 40,000 years ago and coexisted
with Neandertals for 10,000 years, until the latter species died out.
In Tribute to Madame de Pompadour and the Court of Louis XV, 1985, in which bees and snails coexisted
in a conical "court," activating the systems of water and sugar that determined their survival, was represented here by scented handkerchiefs and etched-glass portraits.
In contrast, many researchers suspect that three or more full-fledged species of human ancestors coexisted
A fossil species often classified as a direct human ancestor survived much longer in Indonesia than previously suspected and may have coexisted
for at least several thousand years with Homo sapiens, according to new age estimates for a fossil site in Java.
A younger date would suggest that knowledge about producing these points coexisted
in Siberia and North America or moved back and forth from one continent to the other, they hold.
But pollen studies indicate the modern boreal forest represents a relatively new community that developed only 8,000 years ago although similar mixes of trees may have coexisted
during previous interglacial periods.
Other researchers have uncovered evidence that humans and the extinct mammals coexisted
in Tasmania 20,000 years ago, with the latter group disappearing 11,000 years ago.
