Is there only one ancestor in the world?

The ancestors of human beings were all Australopithecus, and Australopithecus produced many branches due to different environments and regions, including Asian Australopithecus, Southern African Australopithecus, Forest Australopithecus, Rama Australopithecus and other branches, and these Australopithecus eventually evolved into different humans.

No, if there is only one ancestor, then how to reproduce, if inbreeding it is all deformed.

The ancestors of human beings should be the same wave of people, because they were affected by the environment and habits, so there were certain differences, such as differences in skin color, so although there are so many races, they are all the same creatures, and they are now distributed all over the world.

It can be said that it is the same wave of people, but due to the environment at the time, they migrated, so many races have appeared, and they have all developed their own languages and cultures.

The ancestors of human beings are actually the same wave of people, but because of the difference in living environment, the genetic mutation, so the skin color and height of human beings have changed, and the situation is normal.

Because the earth is very large, the environment of each place is different, and many races have been formed, and different races have different living environments. But there are some races that go extinct because they don't adapt to the environment.

Scientists have discovered the earliest ancestors of mankind.

A French team found fossilized bones and teeth of ancient humans in Kenya last year, and after research, scientists found that these may be the earliest ancestral remains ever discovered.

Researchers have shown the fossils to the world, pointing out that they are older than Lucy, an ancient human fossil found earlier, and that they may be more than twice as old as Lucy. This discovery will add more topics to the already fierce debate over the origins of mankind.

The fossils, which include 12 bones and teeth, were discovered last year in central Kenya and prove that Lucy did not have the true ancestor of humans. The latest discovery was announced at a press conference in Paris, and a week later scientists will name the fossil and officially announce the finding.

The oldest human fossils previously discovered were found in Ethiopia, 4.5 million years old, and the 3.2 million-year-old Lucy fossil was found in Ethiopia in 1974 and belongs to another branch of the human ancestral map, but some scientists disagree. Now, these newly discovered fossils prove that the apes were just able to stand up and walk, and that it is likely that Lucy was just a strange-looking ape.
