Answer 1

1. Coelurosaurian dinosaurs are believed to be the nearest relatives of aves, truth be told, birds are viewed as coelurosaurs. This is proved on the basis of Gauthier's and others' cladistic investigations of the skeletal morphology of these creatures. Bones are utilized in light of the fact that bones are the only proof protected in the fossil record.

2. Different lines of evidence that proves the existence of evolution theory are:-

Molecular biology

Comparative embryology and anatomy

Biochemistry and Biogeography

Radioisotope dating

3. The procedure by which types of life having attributes that better empower them to adjust to explicit ecological weights, as predators, changes in atmosphere, or rivalry for nourishment or mates, will in general endure and replicate in more prominent numbers than others of their sort, in this manner guaranteeing the propagation of those good qualities in succeeding generations.
