And, the answer for the the question is :
Explanation:
The shrew-like morganucodontids are the earliest mammals discovered, and they are the ancestors of all modern mammals. About 210 million years ago, they coexisted with dinosaurs. There were other mammalian lineages at the time, but only the morganucodontids survived to give rise to the dominant group of animals on Earth.
Mammals are a diverse and fascinating group of animals that are characterized by a number of unique traits, including the presence of hair or fur, the ability to produce milk to nourish their young, and the possession of a four-chambered heart. The first ancestors of mammals were small, shrew-like creatures that lived over 200 million years ago during the Late Triassic period.
These early mammal ancestors, known as therapsids, were a diverse group of reptiles that were characterized by a number of mammal-like traits, including a more advanced jaw joint and the ability to chew their food more efficiently. Over time, these therapsids continued to evolve and adapt, eventually giving rise to the first true mammals around 150 million years ago during the Jurassic period.
The first true mammals were small, mouse-like creatures that were adapted to a wide range of environments, from the forest floor to the treetops. They were able to produce milk to nourish their young, which allowed them to care for their offspring more effectively and to colonize new habitats.
Over time, mammals continued to evolve and diversify, giving rise to a wide range of different species with unique adaptations and lifestyles. Some mammals, like bats and flying squirrels, evolved the ability to fly or glide through the air, while others, like whales and dolphins, adapted to life in the water and became fully aquatic.
all mammals share certain common characteristics, including the presence of hair or fur, the ability to produce milk to nourish their young, and the possession of a four-chambered heart. These traits, along with their evolutionary history and unique adaptations, help to distinguish mammals from other groups of animals and make them one of the most fascinating and successful groups of organisms on the planet.
the first ancestors of mammals were small, shrew-like creatures that lived over 200 million years ago during the Late Triassic period. Over time, these early mammal ancestors continued to evolve and adapt, eventually giving rise to the first true mammals around 150 million years ago. Today, mammals are a diverse and fascinating group of animals that are found in nearly every corner of the globe, from the depths of the ocean to the highest mountaintops, and have adapted to a wide range of environments and lifestyles.
