Four scenarios for human evolution
| |
Posted on Sunday, November 29 2009 @ 13:07:24 CET by Thomas De Maesschalck |
National Geographic takes a look at four ways the human species may evolve in the future. The first scenario is that human evolution may be dead, while the second possibility is that human evolution may be far from over. The third prediction deals with electronic immortality, and the fourth scenario is that space colonization may split us into more than one species.
Despite up to 30,000 years of partial isolation among populations in places such as Australia and Papua New Guinea, human speciation did not occur, he noted.
But if, in the far distant future, habitable planets beyond our solar system were colonized by Earth migrants, that could provide the necessary isolation for new human species to evolve.
"If we had spacefaring people who went on one-way voyages to distant stars, that might be enough to trigger speciation," Hawks said.
