Human evolution




  • as per their living conditions.
  • Evolutionary relationships between species can be traced easily by using fossils, DNA sequences, excavation, etc. which help us to know about human evolution as well.
  • It is said that human evolution began in Africa and humans are descendants of members of a human species called Homo sapiens that stepped out of Africa and traveled all around the world.
  • They mingled with the new and the old ones to produce a diversity of human species that we see around us.


Acquired and inherited traits

The traits which are acquired by an organism during its lifetime are called acquired traits. These traits are not inherited as these traits develop as a result of changes in the non- reproductive tissues of the organisms. Only the variations in the reproductive cells can be passed on to the next generation.

  • Natural selection, genetic drift, and speciation shaped the biodiversity.
  • Thus, the creation of a huge biodiversity can be attributed to evolution.
  • The new species never mated with the previous ones but reproduced in their own way with their own group members leading to the branching of species i.e., a common ancestor diverges into two or more different lineages.

Human evolution is not from chimpanzees but they share a common ancestor because both the species of human and chimpanzee evolved in their own way from a common ancestor
