Question

Which one of the following supports the ‘multi-regional’ hypothesis of the origin of mode humans from archaic Homo sapiens?
(A) The high variability of nuclear DNA in some modern Africans.
(B) The uniformity in mtDNA among modern human populations.
(C) The oldest known fossils of modern Homo sapiens have been found in Africa.
(D) The existence of distinctive human races.

Answer 1

Hint: Animal species, plant species, or insect species gradually change some of their physical qualities over the course of many generations as a result of the process of evolution.
Step by step solution:
The protracted process of change that separated humans from their apelike forebears is known as human evolution. According to scientific research, the physical characteristics and behavioural features that all humans share have their roots in apelike ancestors and have been evolving for almost six million years. We can solve biological problems that have an influence on our lives by understanding evolution. The realm of medicine is full of fantastic examples of this. Understanding the evolutionary patterns of disease-causing organisms is crucial for researchers who want to keep one step ahead of deadly diseases. The theory of human evolution explains how extinct monkeys on Earth gave rise to current humans. Homo sapiens, an upright, ground-dwelling species, is what we are known as when seen from a zoological standpoint. It is believed that this species originally appeared in Africa about 315,000 years ago.
The development of Homo sapiens as a unique species within the hominid family, which also includes great apes, was the result of the evolutionary process that took place within the history of primates. The process of evolution that transformed ancient H. sapiens into modern humans in various parts of the world is known as gene flow. Gene flow refers to the evolutionary process that changed prehistoric Homo sapiens into modern humans in various places of the world.
So, option (D) is correct.
Note: Charles Darwin established the basic theoretical foundations for the field of human evolutionary research as it is performed today, together with his younger colleague Alfred Russel Wallace.
