In recent years, there has been controversy among biologists about whether Neanderthals should be placed within the same species
as modern humans or into a separate species of their own. Most DNA sequence data analyzed at this point indicated that there was probably little or no gene flow between Neanderthals and Homo sapiens. Which species concept is most applicable in this example?
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.

The main natural carbon sinks are plants, the ocean and soil. Plants grab carbon dioxide from the atmosphere to use in photosynthesis; some of this carbon is transferred to soil as plants die and decompose. The oceans are a major carbon storage system for carbon dioxide.
Higher oxygen levels means animals can grow larger and still maintain the supply of oxygen to their muscles. Falkowski and colleagues calculated fluctuations in the atmosphere's oxygen levels from cores of deep-sea rocks dating back 205 million years.
E) The rock squirrel, spiny lizard and fennec fox are all primary consumers.
Explanation:
Fennec fox is omnivore and they usually live in underground holes. They dig the holes with the help of their feet. They usually consume insects, some plants, eggs and small animals.
