This question is incomplete. However, the answer to this question is Continental Drift. Approximately 300 million years ago, there were not separate continents, only one giant super continent that we call Pangaea. Over time, scientists realised that the Earth's outer shell slides over the inner mantle through plate tectonics. Around 200 million years ago, Pangaea began to break up through the process of continental drift. Gondwana, incorporating present-day <span>Africa, South America, Antarctica, India and Australia, split from Laurasia (Eurasia and North America). Approximately 150 million years ago, Gondwana started to break up into the present day continents</span>

Answer:
The correct answer would be - biological species concept.
Explanation:
The biological species concept is a concept of speciation or how a species forms in nature. According to this, a species is the group of the population that can naturally or potentially interbreed with each other, not on the basis of their physical similarities or habitats.
The physical appearance could be useful as recognizing a species but not defining it. As neanderthals show very little or no gene flow with a modern human it means they do not belong to the same species as modern homo sapiens.
Thus, the correct answer is- biological species concept.
