A.
Climate Change

B.

D.

Expert Solution
Step 1: Answer:- Thus the answer for the above is as follows:-

Neanderthals were an ancient human species that lived in Europe and parts of western Asia around 400,000 to 40,000 years ago during the Middle Paleolithic period. They are named after the Neander Valley in Germany, where the first remains were discovered in 1856. 

Key characteristics and aspects of Neanderthals include:

  1. Physical Appearance: Neanderthals had a robust build, with a stocky and strong body adapted to cold climates. They had a large brain, similar in size or slightly larger than that of modern humans, along with a distinctive skull shape with a prominent brow ridge. They were well adapted to their environment, with physical features such as a large nose and barrel-shaped chest. 

  2. Culture and Tools: Neanderthals were skilled toolmakers and used stone tools, creating handaxes, scrapers, and other implements. They also made use of bone and antler tools.They were capable hunters and are believed to have used a range of hunting strategies to acquire food, including ambush hunting and close-range attacks on large prey. 
  3. Interaction with Homo Sapiens: There is evidence that Neanderthals and Homo sapiens coexisted for a period, with some limited interbreeding. Genetic studies have shown that non-African modern human populations have some Neanderthal DNA, indicating some level of interbreeding between the two species. 
  4. Extinction: Neanderthals went extinct around 40,000 years ago. Various theories attempt to explain their disappearance, including climate change impacting their habitats, competition with Homo sapiens for resources, and potential difficulties adapting to changing environments. 


Thus , the factor which is less commonly considered in disappearance of Neanderthals 

Aquatic Predators (C): This factor is less commonly considered in discussions about Neanderthal extinction. There's limited evidence to suggest that aquatic predators had a direct impact on Neanderthals' decline.
