The process of human evolution

Human evolution originated from forest apes and has gone through four stages: ape humans, primitive humans, sapiens, and modern humans.

Human evolution is a theory gradually developed after Charles Darwin proposed the theory of evolution. It is believed that humans and great apes originated from forest apes and developed step by step from primates through a long evolutionary process. .

This theory is supported by some biologists and archaeologists. Like other theories developed from evolutionary theory, this theory also faces many challenges and difficult-to-explain phenomena. Current biology and archeology circles generally believe that humans originated from forest apes. There are two main theories about the early evolution of modern humans, namely the single-place origin theory and the multi-place origin theory.

Natural selection is not only the core concept in evolutionary biology, but also a key factor leading to biological evolution. From an evolutionary point of view, individuals who can survive are not necessarily the fittest; only those who survive and leave many descendants are the fittest. Stearns, a professor of evolutionary biology at Yale University in the United States, believes that modern humans still cannot escape the process of natural selection.

When genetic mutations occur, life characteristics change. Beneficial mutations are passed down from generation to generation, making relevant traits more and more common in the population, and evolution happens in real time. The revolution in genetic technology has allowed biologists to compare the genetic information of hundreds of thousands of people and explore the processes of natural selection. By tracking the relative increase or decrease of a particular mutation over many generations, it is possible to infer which evolutionary traits are spreading or shrinking.

Scientists are trying to use genetic sequencing and other modern technological methods to study how humans continue to evolve. They believe that humans are acquiring new genes and evolving at an unprecedented rate.
