Question

Mammals are most adapted among the vertebrates. Elaborate.

Answer 1

Mammalian adaptations are the best among vertebrates.

The following are some of the adaptations that animals have shown: 

1. Mammals may be found in a wide range of habitats, including mountains, deserts, grasslands, plains, and even aquatic environments. 
2. Insulation is provided by skin hairs. 
3. Mammals have two sets of limbs that allow them to run, leap, stroll, fly, climb, and burrow. 
4. They are warm-blooded creatures, meaning they can regulate their body temperature. 
5. Sexual dimorphism is well established and serves as a critical survival mechanism. 
6. Sweat glands are found on mammalian skin and aid in osmoregulation and temperature regulation. 
7. External ears aid in the effective capture of sound waves. 
8. The four-chambered heart allows for more effective double circulation than single circulation. 
9. The majority of mammals are viviparous. 
10. This contributes to animals living longer lives.
