Did man evolve from a group of apes, or from just one ape?

The basic unit of biological evolution is the population, and a single biological individual will encounter many accidental factors that cannot pass on the genes, such as accidental death and congenital infertility, only the population can maintain a variety of genes and provide sufficient genetic materials for evolution.

The theory of biological evolution in Darwin's time and soon after has attached great importance to the role of biological populations, emphasizing three aspects:

A certain organism that (based on population) has a strong reproductive capacity and has enough biological individuals to adapt to changes in the environment;

Environmental changes will eliminate a group of people who are not adapted to the environment, and the rest will be more adapted to the environment and continue to reproduce;

Over a period of evolution, the external characteristics and internal genetic attributes of organisms will change, which may lead to the formation of new species.

A single biological individual will be due to a lot of accidental factors so that genes can not be inherited, so the basis of the existence and reproduction of organisms in nature is the population, some endangered species in the final stage of population extinction, usually can also leave both male and female individuals, but can not maintain the population, and even some animals still refuse to mate, there are too few mates to choose from, and artificial technology often fails to assist their reproduction.

The modern theory of biological evolution is still based on natural selection, but with the addition of genetic influences, which were inherent in Darwin's time. Natural selection causes the death of individuals who are not adapted to the environment, and the corresponding assemblage of genes with better adaptability can be retained, which leads to changes in gene frequencies in the gene pool of the population, which in turn leads to changes in the evolutionary defense line of organisms.

From the evidence of human evolution that has been obtained (fossils, ancient charcoal piles and other things with civilization attributes), it can be inferred that human beings were not human beings before, and have experienced evolutionary stages such as Homo sapiens, Homo erectus, and Homo sapiens, and from the perspective of modern human characteristics, they are not human beings, but they belong to intermediate species or branch species that evolved to humans, and there were several ancient human branch species such as Neanderthals and Heidelberg people, who have a certain kinship with modern humans, and also have activities with civilization attributes. It's just that they haven't been able to continue to reproduce to this day, but they once had a genetic exchange with humans, creating humans outside of modern Africa.

According to the study of gene mutation rate and gene diversity, modern humans originated in Africa tens of thousands of years ago, and they have no essential difference from modern humans, but they are still far away from now, and there will be relatively large differences between genes and modern humans.

Personally, I think that it evolved from a group of apes, and the ape that exists alone cannot reproduce on its own in the first place, how to pass it on to the next generation, and how to evolve.

It's a really hard question, but I think it evolved from a group of apes, after all, we are social animals, and at that early on, a single person simply could not survive.

A pack of apes. Because the evolution of organisms is generally based on populations, not individual cases, humans evolved from a group of apes.

Man evolved from a group of apes. And then slowly multiply on the earth, and all the current human beings are formed.
