Why are primates considered the most intelligent mammals?

Answer 1

Mammals are considered the most advanced as they evolved "last" as it were. This meant that the best genetic and phenotype adaptations could be slowly passed on, creating a different species, class and eventually a kingdom.

Mammals posses several aspects that distinguishes them from any other kingdom:

Tooth replacement shared with a few reptiles as well, most mammals have two sets of teeth (though others, such as rabbits have one set, yet these continuously grow) Most mammals also have the enamel that coats the teeth for extra protection.

All mammals can are "warm-blood" which means they can keep homeostasis. Homeostasis is the constant internal temperature despite maybe different external temperatures. For example, if you were to have a mouse and a lizard under a heat lamp, the mouses temperature would be steady as the body is cooling and keeping it at a constant temperature, whilst the lizards internal temperature rises and keeps rising. Lizards and animals that cannot keep homeostasis solely rely on their environment to keep them warm and cool. Because of this, most mammals live in places were reptiles could simply not exist.

Mammals (female) also secrete milk from the mammary gland and nurse there young. This is specialized for mammals- colostrum (first milk) gives young animals a kick-start in life, while milking itself increases offspring and mother bond. Compared to the reptiles or fishes why of breeding, even though lots of offspring (in certain species of fish, millions of eggs) are produce most of them die. This is not as a waste as one would think: these eggs provide vital nutrients for the food chain and ecosystem. However, mammals "look after" there young and protect them: thus prolonging their life.

The largest group of mammals have placentas when they are pregnant, which gives nutrients to the offspring when growing. This is a vital bodily function, and helps with all aspect of the foetus growth. However, many disease can be contracted through the placenta, whilst reptiles do not usually past diseases on through eggs (only through what condition the mothers body is in, i.e.if calcium levels are low, the eggs have soft shells)

Mammals also have the neocortex, which is involved in "high" though processes, such as language, sensory perception, generation of motor commands and conscious thought. In humans the neocortex is relatively big, but you just need to consider the amazement of the human body to understand that.

Answer 2

Mammals are thought to be the most intelligent animals on earth as a result of their brain structure. Squids are the most intelligent invertebrates.

Answer 3

They steal brains.
because they dont worries like we do..

Answer 4

Mammals have a highly developed nervous system. Their developed brain makes them smarter than other animals.
