Primate evolution

Primates are a relatively new species and first appeared in the fossil record nearly 55 million years ago. They may have originated as far back as the cretaceous period. Their fossils were observed in North America, Asia, and Europe. Long before the first monkeys and their prosimian relatives developed, most animal species thrived and died. The first primates did not exist until about 50-55 million years ago, even though the planet is 4.54 billion years old and the first life goes back at least 3.5 billion years. Dinosaurs had been extinct for 10 to 15 million years when this happened.

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. A greater number of winged dinosaurs of the early Cretaceous period become extinct as fewer winged dinosaurs with greater body mass evolve to take over their niche. The extinction of long-necked herbivores in the late Jurassic period provided a greater amount of habitat and food resources for early Cretaceous…
