Are human races like dog breeds?
Population structure of human races and dog breeds. A key assumption of the race-breed analogy is that both human “races” (i.e. U.S. census groupings) and dog breeds are formed and structured in similar ways, with each representing distinct groups within each species.

There are multiple theories around what might ultimately cause human extinction — everything from alien invasions to catastrophic asteroid strikes. But among those investigating this question, there’s a general consensus that some risks to human life are more plausible than others.
What Year Will the Earth die?
Four billion years from now, the increase in the Earth’s surface temperature will cause a runaway greenhouse effect, heating the surface enough to melt it. By that point, all life on the Earth will be extinct.
