You need to specify a time period for the question to be answered. Synapsids, therapsids, and cynodonts could all be called the early ancestors of mammals, but each at a different stage in the evolutionary history of mammals.
The evolutionary precursor to feathers is believed to be structures known as "dino-fuzz" or proto-feathers, which were likely simple filaments or hair-like appendages found on the skin of some theropod dinosaurs. These structures may have originally served insulation, display, or other functions before evolving into more complex feather forms. The transition from these primitive structures to the sophisticated feathers seen in modern birds illustrates an example of evolutionary adaptation and diversification.
Not actually. There were several different marine reptiles that had mammalian characteristics, notably the group known as pelycosaurs. The earliest mammals appeared early in the Age of Reptiles (Mesozoic Era), but were uniformly small in size. The group called synapsids took an evolutionary path to mammals while the sauropsids became today's reptiles and birds.
A giraffe has 7 cervical vertebrae, which is the same as us.
A giraffe, which is likely what you meant by "daraf," has the same number of bones in its neck as humans do. Both species have seven cervical vertebrae; however, each of a giraffe's neck vertebrae is much longer, contributing to its height. In total, a giraffe has about 206 bones in its body, similar to other mammals.
Extinction events, such as the Permian extinction and the KT extinction event. You have adaptive radiation driving evolutionary change after such events. Google " the rise of the mammals. "
An evolutionary biologist is least likely to collect data by doing controlled experiments. Evolutionary biologists study living organisms through the lens of evolutionary theory.
evolutionary forces is most likely to decrease variation between populations
