- 1. 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
- 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)
- Fur keeps the body warm helps for maintaining homeostasis
- Mammary Glands -these organism feed their offspring withmilk all the nutrients needed by the baby
- Three middle ear bones-transform sound vibrations into neural impulses(10)
8. Protection and survival
- Immune system- systemof biological structures andprocesseswithin anorganismthat protects againstdiseaseby identifying and killing the intruders
- White blood cells- cellsof theimmune systemdefending the body against bothinfectious diseaseand foreign materials
- Physical adaptations- such asgood insulation , and by specialforms of behaviorsuch ashibernationandmigration 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 ingroupsin order to avoid predators
- Alarm signals- some mammals use different signals in order to inform one another of upcoming danger(3)
10. Why move?
- Skeleton structural support and movement support
- Muscles strong myofibrils, attached to the bone to move it
- Land mammalshave 4 legs (or 2 legs and 2 arms)
- Water mammals- sleek, streamlined bodies
- Mammals need to move toacquire food plants or other animals(4)
- Predators 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)
12. I think therefore I exist
- Mammals have the most complex nervous system on the planet, with humans being the most advanced
- Central nervous system (CNS)-the part of thenervous systemthatcoordinatesthe activity of all parts of the bodies
- Brain -largest part of the central nervous system . Itregulatesmany different functions of the body of a mammal. The brainprocesses all incoming external stimuli , andtells the body what to do in response . In most mammals, these responses areautomaticandunconscious .
- SpinalCord-linkingthe brain to the rest of the body(8)
- Peripheral nervous system (PNS)-made up of only connecting nerves
- Somaticnervous system- controls both the muscles and the information that is processed by the skin and other receptors
- Autonomic nervous system
- Sympathetic nervous system - responsible forinitiating the flight or fight response , which prepares the body to handle dangerous situations
- Parasympathetic nervous system- works toregain homeostasisafter the body has undergone a flight or fight response(8)
- Dolphins are some of Earths most famous mammals
- They inhabit oceans worldwide
- Their natural habitats include
- bays, lagoons, rivers,
- and coastal waters
- Their diet consists mostly
- ofsmallerfish (12)
- Locomotion: Do lph ins normally swim at23-25 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)
