Check sibling questions

Why are human beings who look so different from each other in terms of size, colour and looks said to belong to the same species?



A species is a group of organisms that have similar characteristics and can reproduce to form fertile offspring.

  • Human beings in different parts of the world look different and have different genetic makeup.
  • But they can still reproduce with each other and produce fertile offspring.
  • Thus, due to the absence of reproductive isolation (inability to reproduce), they belong to the same species, in spite of their differences.
