Mammals are considered as most complex of all the vertebrates. The reason is very simple! Man belongs to this category. Man is supposed to be most evolved of all. (Supposed to be. For that man has done most of the damage to the earth.) Man has got the most intelligent brain. Most of the mammals are more or less intelligent. Human brain is the most complex of all the organs.
In terms of brain capacity, the most complex mammal is a human. In order to answer your question fully, you need to clarify what you meant by "complex."
They produce milk for their young, give live birth, and have a diaphrgam. Those are the 3 main things.
why mammals are the most complex vertebrates
Mammals are ectothermic (warm blooded), have a 4 chambered heart, specialized teeth, body covering of fur or hair, and suckled their young.
Vertibrates.
A mammal is a type of animal.
Cats are vertebrates.
fish
Yes, mammals are vertebrates.
Of course. It's a mammal; mammals are vertebrates; all vertebrates have backbones.
A raccoon is a mammal and is a vertebrate.
No it's a bird
It's a vertebrate, it has a backbone. In fact, it's a mammal, and all mammals are vertebrates.
The vertebrate group in which humans belong to is the mammal group.Humans belong to the Mammal group.
They have a backbone
Except for the brain, humans have a body that is as complex as any other mammal's.
All but the insect are vertebrates.
