Dinosaur and ancestral bird fossil data from the Triassic, Jurassic, and Cretaceous time periods were used to estimate body mass. Scientists are examining the connection between body mass, niche saturation, and extinction of species in the Triassic, Jurassic, and Cretaceous time periods. The terrestrial dinosaurs’ neck length and diet are compared to the evolution of the winged dinosaur through the three time periods.   Which of the following statements best states the null hypotheses regarding winged dinosaurs? The greater number of herbivore dinosaurs throughout all the periods inhibited the evolution of winged dinosaurs due to a lack of available resources and habitat.

Marine Evolution

Marine habitat is less explored, and hence, its biological diversity is far less known. The marine habitats are not constant due to their shifting nature, while the terrestrial habitats are more stable. Marine biology is the science that deals with the study of diverse marine species, their interactions, and behavioral characteristics.
