Answer:
1. Molecular evidence: similar proteins and genes found in closely related species, even if those genes are not used by an organism.
2. Fossil evidence: organisms changing form over time through the fossil record.
Direct observation. We can directly observe small-scale evolution in organisms
with short lifecycles (e.g., pesticide-resistant insects).
Explanation:
The correct answer is option C, that is, mammals were able to diversify to make use of the variety of habitats that were previously occupied by dinosaurs.
Adaptive radiation refers to the comparatively fast evolution of various species from a single common ancestor. Adaptive radiation usually takes place when a species enters a novel area and distinct traits influence its existence. An illustration of adaptive radiation is the progression of mammals after the annihilation of dinosaurs.
Answer:
The history of the human evolution can be studied by the fossil and DNA evidence. The similarities and advancement in certain characters has revealed the human evolution.
Different evidences like change in the diet, locomotion, brain size, walking ability as compared with the present species and species appeared 6 million years ago. The human genetics evidence and different paintings explain the culture of earlier homo species.The H. sapiens species has highly advance character that help them to survive than any other hominid species. The neanderthals extinction might occur due to their aggressive behavior, low social ability and their large cranial size.
