The most “advanced” and modern among the

animal kingdom

Mammalia - The young are nourished for a time by milk, or an analogous fluid, secreted by the mammary glands of the mother.

According to scientist at first milk was just used to moist eggs

Domain - Eukarya Kingdom - Animalia Phylum – Chordata Class – Mammalia 

Class – Reptilia (Reptiles)

Class – Aves (Birds)

Class – Amphibia

Humans are primates – one of the orders of the class

The earliest mammal is Eozostrodon – a rodent quite big over a meter long(2)

1) Fur – keeps the body warm – helps for maintaining homeostasis

2) Mammary Glands-these organism feed their offspring with milk – all the nutrients needed by the baby

3) Three middle ear bones- transform sound vibrations into neural impulses(10)

Protection and survivalProtection and survival Immune system - system of

biological structures and processes within an organism that protects against disease by identifying and killing the intruders

› White blood cells -  cells of the immune system defending the body against both infectious disease and foreign materials

Physical adaptations - such as good insulation, and by special forms of behavior such as hibernation and migration – cause of evolution(9)

Armaments made of Keratin - horns, spines, and quills

Camouflage - use their natural coloring to blend in with their surroundings

Some mammals feed in groups in order to avoid predators

Alarm signals - some mammals use different signals in order to inform one another of upcoming danger(3)

Why move? Skeleton – structural

support and movement support

Muscles – strong myofibrils, attached to the bone to move it

Land mammals have 4 legs (or 2 legs and 2 arms)

Water mammals - sleek, streamlined bodies

Mammals need to move to acquire food – plants or other animals–(4)

PredatorsPredators – need to be faster and stronger to be able to kill

“Victims” – need to be faster and smaller to be able to escape

Unique – some have skin formed between their legs or fingers – used for flying(7)

I think therefore I existI think therefore I existMammals have the most complex nervous Mammals have the most complex nervous

system on the planet, with humans being system on the planet, with humans being the most advancedthe most advanced

Central nervous system (CNS)- the part of the nervous system that coordinates the activity of all parts of the bodies› BrainBrain - largest part of the central nervous

system. It regulates many different functions of the body of a mammal. The brain processes all incoming external stimuli, and tells the body what to do in response. In most mammals, these responses are automatic and unconscious.

› Spinal Cord Spinal Cord - linking the brain to the rest of the body(8)

Peripheral nervous system (PNS)- Peripheral nervous system (PNS)-  made up of only connecting nerves

Somatic nervous system-Somatic nervous system-controls both the muscles and the information that is processed by the skin and other receptors

Autonomic nervous system› Sympathetic nervous systemSympathetic nervous system - responsible for

initiating the flight or fight response, which prepares the body to handle dangerous situations

› Parasympathetic nervous system Parasympathetic nervous system - works to regain homeostasis after the body has undergone a flight or fight response(8)

Dolphins are some of Earth‘s most famous mammals

They inhabit oceans worldwide Their natural habitats include bays, lagoons, rivers, and coastal waters Their diet consists mostly of smaller fish(12)

Locomotion: Dolphins normally swim at 23-25 mph

They swim fast and are able to swim on their bellies, backs, and sides; they can also jump quite high

Life cycle: Birth, calf, adult Bottlenose dolphins can detect sound

at extremely high frequencies unnoticeable by human ears(12)

Cheetahs mostly inhabit the savannas of Southern and Western Africa

Their diet consists of calves, impalas, gazelles, antelope, and hares

The fastest land animal – can run at up to 113 kmph in short

bursts due to its light build, large heart, and small amount of stored fat(6)

Cheetahs have special paw pads and retractable claws

Their large nostrils allow them to breathe in a bigger amount of oxygen

The small amount of fat they can store means they have little energy at hand

Life cycle: Birth, cub, adult Often hunted down because of their beautiful fur(6)

Brown bears reside in the mountains and forests of North America, South America, Europe, and Asia

Their diet consists of plants, fruits, nuts, insects, fish, birds, and mammals

Bears move with their metatarsals flat on the ground(11)

Life cycle: Birth, cub, adult Bears possess a sense of smell seven

times as powerful as that of dogs Bears’ powerful memory helps them

relocate old food stashes Bears are popular among children and

are often mascots for various projects, like Smokey Bear(11)
