Answer:
Step-by-step explanation:
statement is not accurate. The evolution of cynodonts and the appearance of the first mammals occurred during different periods of geological time.
Cynodonts were a group of therapsids, which were synapsid reptiles that lived during the Permian and Triassic periods, approximately 299 to 201 million years ago. Cynodonts were important in the evolution of synapsids towards a more mammal-like morphology, including features such as a secondary palate, differentiated teeth, and a more erect posture.
The first mammals, on the other hand, appeared during the Mesozoic Era, specifically in the Late Triassic period, around 220 million years ago. These early mammals were small, shrew-like creatures that likely lived in a nocturnal lifestyle and were likely insectivorous.
Therefore, the evolution of cynodonts towards a more mammal-like form and the appearance of the first mammals occurred during different periods of geological time, with cynodonts appearing earlier in the Permian and Triassic periods and the first mammals appearing later in the Late Triassic period of the Mesozoic Era.
