the extinction of most dinosours
Their habitat has forced some mammals to live that way.
no
Adaptive radiation is usually caused by the appearance of a very useful adaptation or the appearance of a new niche in an ecological community. Both contributed to mammals' adaptive radiation. They evolved molars with four cusps, which increased their potential diet. They were insulated by fur, allowing them to survive colder areas and colder times. And the non-avian dinosaurs became extinct, allowing mammals to take their place as the (on average) largest and most dominant organisms in many ecosystems. ---------------------- PLATO USERS D) Both A and B
because they have the same flesh daaaaaaaaaaaaaa:)
No.
No, penguins are not marine mammals. They are birds that are adapted to living in aquatic environments. Marine mammals include animals like whales, dolphins, seals, and sea otters.
The ones who adapted to i.e. Mammals, Birds, Reptiles, Amphibians, Insects.
Mammals have adapted to live in many different environments on the planet. They can be found at the poles, in the deserts, in the oceans, flying in the sky and many others.
Humans are very unique among all the numerous mammals. So far, we have evolved and adapted the most. Hope this helped! :)
Two key theories that explain why some marsupial mammals are only found in Australia are the "Isolation Theory" and the "Adaptive Radiation Theory." The Isolation Theory suggests that Australia has been geographically isolated for millions of years, allowing unique marsupial species to evolve without competition from placental mammals. Meanwhile, the Adaptive Radiation Theory posits that after the extinction of dinosaurs, marsupials rapidly diversified and adapted to various ecological niches in Australia, leading to a rich variety of species that are now endemic to the continent.
In this context, radiation means divergence: the emergence of multiple populations, each adapted to their particular niche or otherwise changing relative to their ancestors and siblings, from a common ancestor.
Yes. They're mammals, and are adapted for life in cold weather.
