Humans will suffer a mass extinction because humans are not use to change like ice ages even though we are between ice ages right now.

Where did early humans migrate about 12000 years ago?

Early humans migrated to various regions around the world about 12,000 years ago as part of the process of human expansion and settlement. This period marked the end of the last ice age, leading to the development of agriculture in regions such as the Middle East, China, and the Americas. This migration and exploration of new territories allowed early humans to adapt to different environments and develop diverse cultures.


Homo sapiens that lived during the ice age was called what?

Cro-magnon or homo sapiens sapiens. By the end of the last ice age, we had evolved (as best we can tell) into the form we currently have.


What is the genetic mechanism that may have been responsible for the base sequence changes between humans and gorillas?

Many genetic changes happened. One involved the joining of two "ape" chromosomes (they have 24 pairs of chromosomes) end to end to make human chromosome #1 (we have 23 pairs of chromosomes, but still have about the same amount of genetic material). This would have made it impossible for the "new" humans to successfully breed with their most recent prehuman ancestors, even though both peoples probably had identical appearance and lived together for several generations of both.


Did early humans ride on the backs of animals to get from place to place more quickly?

No, our prehuman ancestors that appeared a million or more years ago through the first modern humans that appeared about 100000 years ago only went from place to place by walking on their own two feet. Humans did not begin domesticating any animals other than dogs until shortly after the end of the last ice age, about 12000 years ago. Dogs were domesticated about 15000 years ago, to assist hunter-gather peoples. But humans cannot ride on the backs of dogs. The first animal domesticated that humans rode on the backs of to get from place to place more quickly was the horse, this did not happen until about 5500 years ago in what is now the Akmola Province of Kazakhstan. These people were fully modern humans (in no way "early humans") that first domesticated and rode horses.


Earliest known humans to live in Maine?

The earliest known humans to live in what is now Maine were the Paleo-Indians, who arrived around 12,000 years ago at the end of the last Ice Age. These nomadic hunter-gatherers were the first inhabitants of the region.
