Discovery of Mammals
There are 225 million years, reptiles
mammalian
gave birth to the group Pantothériens,
the current strain of Mammals.
LIGHTING
They then proliferated in the early Tertiary,
there were 65 million years, with the disappearance of the dinosaurs.
The most advanced, man (Homo erectus),
is published there are only 3 million years
Position in the animal world:
The mammals are the most advanced
of the animal world
Despite their small numbers: about 5 900 species
- In comparison:
The Reptiles = 9 080 species
Birds = 10 030 species
Fishs = 31 300
Insects = more than 1 million species
Features:
They differ from other animals by certain characters:
- Method of reproduction specific
the growth of embryos is provided by a placenta in the womb (except among Monotrèmes)
- Breast-feeding their children
- Internal temperature constant, and coat more or less developed

MORE ABOUT
Discover species by Group resemblance
This selection list introduced mammal species, grouped by the principle of comparative anatomy, morphological similarity and geographical location.
(See the menu Taxinomy, for more information on the classification of mammals).
Knowing all mammalian species
Scientists consider that a species is distinct by the fact that it can not reproduce with each other.
This list shows all the species listed by their common name.
Recognize mammalian
Mammalian species have a wide variety of morphological differences due to factors such as mode of reproduction, diet, mode of locomotion, habitat,....
single species may include several sub-species, which differ by physical criteria (coat, size ,...), often related to the geographical area in which they live.
