Solution

Modern humans emerged in Africa during the past two hundred thousand years and developed from their most probably recent common ancestor, Homo erectus. In fact, in Africa, there is more genetic diversity than in the rest of the world.

Homo erectus extinct, between 1.9 million and 135,000 years ago human species.

Modern man (Homo sapiens) has evolved from ancestors which were common to both apes and humans.
Dryopithecus is considered to be the common ancestor of apes and man.
Dryopithecus evolved into Ramapithecus.
then a series of ancestors were present. like
Australopithecus, homo habilis, Homo erectus, java man, Peking man, Heidelberg man, Neanderthal man, and lastly cro-magnon man.
cro - magnon man then evolved to become the modern man.
In evolution, we can observe the main difference in the cranial capacity. the cranial capacity increased with the evolution of man.
we can also observe the development of culture, hunting habits, and tool-making skills.
Dryopithecus and Neanderthal man are not considered to be in a direct line of evolution of the modern homo sapiens ( modern man)

Compared to the genome of Neanderthal, human genomes are closer to each other than each of them is similar to the genome of Neanderthal.
