An overview of the lessons included in the Mammals 101 online course.
An Introduction to Mammals (Mammals 101 - Topic 1)
To understand mammals, it first helps to understand how they fit into the classification system of all animals. Mammals, as a group of animals, belong to the Class Mammalia.
Mammal Adaptation (Mammals 101 - Topic 2)
Mammals have successfully adapted to and colonized a wide variety of habitats including land, air, and water. Their widespread success is largely due to their ability to regulate their own body temperature.
Mammal Classification (Mammals 101 - Topic 3, Part I)
Animals are classified into groups (such as kindom, phylum, class, order, family, genus, species) that reflect how they are related to one another. In this classification system, mammals are grouped into their own class (Class Mammalia) which belongs to the Kingdom Animalia and the Phylum Chordata.
Mammal Classification (Mammals 101 - Topic 3, Part II)
Animals are classified into groups (such as kindom, phylum, class, order, family, genus, species) that reflect how they are related to one another. In this classification system, mammals are grouped into their own class (Class Mammalia) which belongs to the Kingdom Animalia and the Phylum Chordata.
Mammal Classification (Mammals 101 - Topic 3, Part III)
Animals are classified into groups (such as kindom, phylum, class, order, family, genus, species) that reflect how they are related to one another. In this classification system, mammals are grouped into their own class (Class Mammalia) which belongs to the Kingdom Animalia and the Phylum Chordata.
Mammal Evolution (Mammals 101 - Topic 4)
Early mammals shared the planet with the dinosaurs. Some of the primitive mammals (which included early marsupials and insectivores) that lived during the latter part of the Cretaceous period (144mya-65mya) survived the global catastrophe that brought about the extinction of the dinosaurs.
Mammal Research and Conservation (Mammals 101 - Topic 5)
Mammal research and conservation is a vast subject. Studies and protection efforts are often aimed at a single species or a small number of species. Below, you will find information about various areas of mammal study such as primatology, marine mammal research, carnivore research and many others.
