DNA suggests that, like most other European hunter-gatherers of the time, he had dark skin combined with blue eyes. Genetic analysis shows that the Neolithic farmers, by contrast, were paler-skinned with brown eyes and black or dark-brown hair.

Q. Can humans survive an ice age?

Many people believe animals and plants can adapt to modern day climate change because they did so during the Ice Age.

Will humans go extinct from climate change?

Extinction risk is increased under all RCP scenarios, with risk increasing with both magnitude and rate of climate change. Many species will be unable to track suitable climates under mid- and high-range rates of climate change during the 21st century. Lower rates of climate change will pose fewer problems.

Q. When did humans almost go extinct?

Genetic bottleneck in humans According to the genetic bottleneck theory, between 50,000 and 100,000 years ago, human populations sharply decreased to 3,000–10,000 surviving individuals.

Q. What year will the earth end?
