Reef-building corals were
confined to relatively shallow depths because
many of these corals have microscopic algae
called zooxanthellae living inside their soft tissues.
These algae
are often important for the corals’ nutrition and
growth, but require sunlight for photosynthesis. There is no sunlight deep in the water.
Answer:
<em>The correct option is B) Darwin</em>
Explanation:
Darwin was the scientists who studied similarities between species all around the globe and believed that all the species came from a common ancestor. Hence, Darwin was the scientist who proposed the idea of studying humans as groups rather than as individuals.
Other options, like option C, are false because Lamarck believed in the theory that organisms acquired traits from the environment as they grew and they could pass these traits to their children. Hence, these studies did not involve the grouping of individuals.
