Respuesta :
Explain how we know that there are no races (biological subspecies) in modern humans?
Answer:
The correct answer is:
•There is no evidence from any morphological or genetic measures that supports the division of modern humans into subspecies.
Explanation:
Biologists have always defined 'race' on the basis of their ecological, geographical, climatic, physiological and even seasonal criteria. But they've always neglected this classification on the basis of their biological rank.
Question.
Explain how we know that there are no races (biological subspecies) in modern humans
Answer:
There is no evidence from any morphological or genetic measures that supports the division of modern humans into subspecies.
Explanation
The answer is definitely NO!. This is because generally in order for an organism to be subdivided into subspecies, with molecular evidences,
1. The lineage must not overlap with one another, that is they must be separated.
2. The territories occupied by such organism must be clearly marked out,, with no mixing or interbreeding between them so that no gene flow exits.
Evidently these are not possible in , homo sapiens. Homo sapiens had for years migrated and interbreeded with continuous gene flow within the population. Thus division into subspecies is not possible. No doubt mutations leading to variation has made man to have changes in phenotype, these phenotypic changes are not substantiated enough to classify man into subspecies.
