Solution:

Irrespective of their races, all humans are a single species. We can notice features like:

  1. A common body plan, structure, physiology and metabolism.
  2. A constant chromosome number, i.e., 46.
  3. Genetic makeup is also similar, almost 99.9% DNA is same in all humans.
  4. Can freely inter-breed to produce off-springs.

Evolutionary events indicate the origin of humans from a common African ancestor. Homo sapiens (earliest members of the human species) can be traced there. On the basis of above information, we can conclude that all human races seem to have common ancestor.
