1 Bird Vocab Quiz- Study Vocab!!!!

2 Kingdom Animalia Phylum Chordata Subphylum Vertebrata Class Mammalia SZ2- Students will explain the evolutionary history of animals over the geological history of Earth. Mammals evolved from early synapsid reptiles

3 3 Primitive Chordate

4 4 Fish Two Chambered Heart

5 5 Amphibian Heart- 3 Chambers

6 6 Reptilian Heart – 3 chambers Crocodile- incomplete 4

7 7 Fig. 48.28

8 8 Synapsids Animals with one skull opening behind eye socket Located in the temporal region

9 9 Pelycosaurs Synapsid reptiles from Pennsylvanian and Permian – 300-245 MYA Body close to ground Legs away from body Canine like teeth Dimetron

10 10 Therapsids Before dinosaurs Evidence suggests Mammals evolved from therapsids Body raised off the ground Limbs more under the body Teeth differentiated into 3 types Lystrosaurus

11 11 Cynodonts “dog tooth” Lumbar ribs reduced or absent Well developed secondary palate Lower jaw reduced to one bone Cynognathus Thrinaxodon

12 12 Transitional Fossil Thrinaxodon 250-245 mya Body divided into lumbar and thoracic regions

13 13 Transitional Fossil Cynognathus 245-230 mya May have been endothermic and gave birth to live young Smaller than a wolf

14 14 Mammals Cynodonts Therapsids Pelycosaurs Canine like teeth Limbs under body, different types of teeth Reduced ribs, 1 jaw bone Molars, hair, glands Synapsid reptiles Cladogram of Synapsids

15 15 Early Mammals Triassic – 225 MYA Small Megazostrodon

16 16 Repenomamus robustus Ate Dinosaurs

17 Kingdom Animalia Phylum Chordata Class Mammalia 1.Have fur/hair 2.mammary glands 3.Viviparous- Give birth to live young (except monotremes) 4.Length of time in uterus - gestation period 5.Extended parental care 6.4 chambered heart 7.endothermic

18 1.Muscular Diaphragm 2.Specialized teeth 3.Seven cervical(neck)vertebrae 4.Outer ear 5.Well developed brain- Largest cerebrum 6.Sweat glands 7. Diphyodont teeth Two sets 8. Heterodont teeth Different shapes and functions Mammalian Anatomical Adaptations

19 19 Basic Mammal

20 20 Lion

21 21 Rhinoceros

22 22 Gorilla

23 23 Chimpanzee

24 24 Chimp and Human

25 25 Bat

26 26 Same bones, different stance

27 27

28 28 Incisors

29 29 Canine

30 30 Premolars

31 31 Molars

32 32 Mammal Circulation

33 33 Fig. 31.12

34 Humans Reunite with Animals They Raised /today-today_pets_and_animals/t/hugging- lions-ex-owners-reflect-his-legacy/ /today-today_pets_and_animals/t/hugging- lions-ex-owners-reflect-his-legacy/ sciences/gorilla-reunites-with-the-man-who- raised-him-video.html sciences/gorilla-reunites-with-the-man-who- raised-him-video.html

35 35 Mammal Classification 14 major orders Over 4,000 species About half are rodents

36 36

37 37 Monotremes “cloaca” Lay eggs Incubate 12 days Lick milk from mothers fur Transitional species Ex. Echidna, duck-billed platypus

38 38 Marsupials Pouched mammals Birth to tiny embryo Embryo attaches to mother’s nipple to complete development DQ8

39 39 Marsupials and Monotremes in Australia Triassic Period – Mammals evolved – Pangea Jurassic Period – Monotremes and marsupials migrated to southern pangea Cretaceous Period – Pangea breaks up

40 40 Placental Mammals Placenta nourishes embryo Long gestation period – 22 months for elephant Most successful group of mammals

41 41 Placental Mammals Competitive advantage over monotremes and marsupials – Better nutrition from placenta – Less vulnerable to predators More advanced at birth

42 42 Evolution of Placenta from Amniotic Egg Reptile Chorion – Oxygen from air Amnion – Provides private pond Yolk Sac – Food for embryo Allantois – Store urinary waste Mammal Chorion – Form placenta to get oxygen & food from mothers blood Amnion – Provides private pond Yolk sac – Temporarily make RBCs Allantois – Form umbilical cord

43 43

44 44 Placental: Order Insectivora Sharp-snout Small Burrow underground Eat insects

45 45 Order Chiroptera Only Flying mammals Elongated fingers Echolocation Ex. bats Importance- Seed dispersal Pollination Control insects

46 46 Echolocation underwing-moth.html animals/dolphins-and-porpoises/narwhals.html

47 47 Smallest Mammal Kitti’s hog-nosed Bat Bumble bee size 1.5 grams

48 48 Order Xenarthra Toothless or peg like teeth

49 49 Order Carnivora Large canine teeth Teeth adapted to shear flesh

50 50 Order Rodentia Chisel-like incisor teeth Continuously grow Largest order

51 51 Order Cetacea “large sea animal” Front limbs modified into flippers No hind limbs Marine

52 52 Whales Blue whale 100 feet long, 120 tons – 9 story building Loudest animal– 188 dB Sound travels 100’s of miles

53 53

54 54 Blue Whale Baleen whale Eats krill – Tiny crustaceans – 400 pounds/day Heart weighs 1000 pounds – Size of a Volkswagen Endangered species

55 55 Grey Whale

56 56 Migrates 12,500 miles

57 57 Grey Whale 50 feet long 35 tons Baleen whale – Sift mud Endangered species

58 58 Killer Whale

59 59 Breaching

60 60 Killer Whale 12,000 pounds Eat fish, squid, seals and whales – 200 pounds/day Swim 30 mph

61 61 Humpback Whale

62 62 Order Pinnipedia “fin feet” Limbs modified for swimming Marine carnivores Seals, sea lions, walrus

63 63 Order Proboscidea Tusks Largest living land mammal

64 64 Order Artiodactyla “even toe” Two or four toes Giraffes, impalas, moose, bison, cows

65 65 Order Perissodactyla “odd toed” One or three toes Horses rhinos

66 66 Order Primata Opposable thumb Binocular vision Fingernails usually Mammary glands reduced to one thoracic pair Most intelligent group of animals

67 67 The End

68 Evolution Change over time Which Chordate class do you think has more advantages/adaptations to survive changing times? Which classes have disadvantages? Which Chordate classes can you see evolutionary similarities in so far?
