Indians may closely resemble Europeans in terms of biological traits due to genetic allele frequencies.

The oldest skeleton from Europe that has been found so far is anatomically modern and dates to between 34,000 and 36,000 years ago. It was found in Romania's Carpathian Mountains. Conclusions drawn from the fossil evidence are supported and expanded by data already available on human genetic variation.

The conventional racial divisions, according to some observers, is biologically and genetically justified by these patterns of variation. According to their claims, the distribution of humans among sub-Saharan Africans, European, West Asians, and North Africans, Eastern Asians, Polynesians and other Oceanian residents, and Native Americans largely corresponds to the grouping of the continents.

<h2>Answer:</h2>

The two reasons are given below:

  • Natural selection.
  • Lack of food
<h3>Explanation:</h3>

Natural selection is the phenomenon of the evolution in which the organisms able to fit in the changing environment survive while other organism died. Hence the survival if the fittest and then these organisms. Further reproduce to give birth organisms more fit to the changing environment.

The long neck giraffe survive but short neck died. So the population of long neck increased while short neck go extinct.

Other reason is the change of food resource. The food resource change from grass to long trees.
