We understood that human beings evolved and adapted over the years. But can we say evolution means progress?

Not really! Let’s see why:

  • At each stage of evolution, there are multiple branches.
  • Emergence of a new species does not mean old species are wiped out , both might exist.
  • It is not necessary that the new form of the organism is better adapted than the old form; as we discussed, the new organism may be a result of genetic drift (accident) or natural selection.
  • Human beings did not evolve from Chimpanzees . Instead both humans and chimpanzees have a common ancestor. Thus chimpanzees and humans exist at the same time.
  • On the other hand, ‘progress’ could be seen in the complexity of these evolved organisms .
  • But even then it is interesting to see how less complex organisms like bacteria are present in all kinds of environments but not complex organisms like humans.

Human evolution

Of all organisms, we would be most excited to know about how human beings evolved over the years.

  • The scientific name of human beings is Homo sapiens .
  • The earliest members belonged to Africa .
  • Some continued to live there while some migrated to other countries.


  • These humans who migrated did not just move out , they went back to where they came from as well. 
  • Sometimes humans who migrated to different countries also mixed with each other.

Like all other organisms, we are also a result of accidental evolution accumulated over the years and we are successfully thriving on this planet.
