Answer:
(A) Bioaccumulation
Explanation:
When the concentration of certain substances in the bodies of the organisms of various trophic levels keeps on increasing as they pass through the food chain, the process is called bioaccumulation or biomagnification.
Most of the organic non-biodegradable pollutants/chemicals exhibit bioaccumulation. Being insoluble in water, these chemicals are accumulated in the fat tissues of the organisms.
As the predator feeds on the prey having a non-biodegradable chemical in its tissues, the chemical enters the body of the predator.
As these chemicals pass through the food chain, there is a gradual increase in their concentration stored in the living tissues of the organisms. Therefore, the top consumers exhibit maximum bioaccumulation of contaminants in a food chain.
Taphonomists would probably conclude that hominins had scavenged meat from an animal carcass, they did not kill if fossil animal bones; did not contain stone cut marks, which are easily distinguishable from tooth marks.
Some characteristics that have distinguished hominins from other primates, living and extinct are their erect posture, bipedal locomotion, larger brains, and behavioral characteristics such as specialized tool use, and in some cases communication through language.<span />
