Slide 1

Area Bacteria Domain Archaea Domain Eukarya Common precursor Kingdom: Animals Domain Eukarya Click the "Slide Show" catch at the lower right of the window to begin the show. At that point hit the SPACEBAR to progress.

Slide 2

Animal Characteristics Heterotrophs must ingest others for supplements Multicellular complex bodies No phone walls permits dynamic development Sexual multiplication no shift of eras no haploid gametophyte

Slide 3

Animal Evolution Cnidaria Nematoda Annelida Echinodermata Porifera Platyhelminthes Mollusca Arthropoda Chordata wipes jellyfish flatworms roundworms mollusks divided worms creepy crawlies insects starfish vertebrates body & mind measure,  versatility spine excess, specialization,  portability division  body estimate endoskeleton  stomach related sys coelom outspread body multifaceted nature  stomach related & repro sys body cavity respective symmetry particular body arrange; cephalization tissues specific structure & work, muscle & nerve tissue specialization &  body intricacy multicellularity two-sided Ancestral Protist

Slide 4

pseudocoel coelom depression acoelomate Body Cavity ectoderm mesoderm Space for organ framework advancement increment stomach related & conceptive frameworks increment sustenance limit & absorption increment gamete creation Coelem mesoderm & endoderm associate amid improvement permits complex structures to create in stomach related framework ex. stomach endoderm pseudocoelomate ectoderm mesoderm endoderm coelomate ectoderm mesoderm endoderm protostome versus deuterostome

Slide 5

Invertebrate: Porifera sustenance taken into every cell by endocytosis Sponges no particular tissues or organs do have specific cells no symmetry sessile (as grown-ups)

Slide 6

Invertebrate: Cnidaria Jellyfish, hydra, ocean anemone, coral tissues, yet no organs two cell layers spiral symmetry predators arms encompass gut opening extracellular processing discharge chemicals into gut depression ingestion by cells lining gut polyp medusa

Slide 7

mouth appendages tactile cell released nematocyst stinging cell undischarged nematocyst hydra trigger stinging cell with nematocyst Stinging cells of Cnidarians

Slide 8

ectoderm mesoderm endoderm Invertebrate: Platyhelminthes Flatworms tapeworm, planaria for the most part parasitic respectively symmetrical have right & left & then have head (front) end & back end cephalization = improvement of cerebrum convergence of sense organs in head increment specialization in body arrange Animals now confront the world head on ! acoelomate

Slide 9

Invertebrate: Nematoda Roundworms reciprocally symmetrical body pit pseudocoelom = basic body hole stomach related framework tube going through length of body (mouth to rear-end) many are parasitic hookworm C. elegans

Slide 10

Invertebrate: Mollusca Mollusks slugs, snails, shellfishes, squid reciprocally symmetrical (with exemptions) delicate bodies, generally secured by hard shells genuine coelem builds unpredictability & specialization of interior organs

Slide 11

Invertebrate: Annelida Segmented worms night crawlers, leeches portions increment portability excess in body areas respectively symmetrical genuine coelem fan worm siphon

Slide 12

Invertebrate: Arthropoda Spiders, creepy crawlies, scavangers best creature phylum reciprocally symmetrical divided specific sections permits jointed members exoskeleton chitin + protein

Slide 13

Arthropod bunches 8-legged creature 8 legs, 2 body parts bugs, ticks, scorpions shellfish gills, 2 sets radio wires crab, lobster, barnacles, shrmp bugs 6 legs, 3 body parts

Slide 14

Invertebrate: Echinodermata Starfish, ocean urchins, ocean cucumber radially symmetrical as grown-ups prickly endoskeleton deuterostome loss of two-sided symmetry?

Slide 15

Invertebrate brisk check… Invertebrates: Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Mollusca, Arthropoda, Echinodermata Which assemble incorporates snails, mollusks, and squid? Which gathering is the wipes? Which are the flatworms? … sectioned worms? … roundworms? Which aggregate has jointed extremities & an exoskeleton? Which two gatherings have outspread symmetry? What is the versatile favorable position of reciprocal symmetry? Which amass has no symmetry?

Slide 16

Chordata Vertebrates angle, creatures of land and water, reptiles, flying creatures, warm blooded creatures inward hard skeleton spine encasing spinal segment skull-encased cerebrum deuterostome empty dorsal nerve rope gets to be mind & spinal string gets to be gills or Eustachian tube Oh, look… your first infant picture ! pharyngeal pockets gets to be vertebrae postanal tail gets to be tail or tailbone notochord

Slide 17

450 mya salmon, trout, sharks Vertebrates: Fish Characteristics body structure hard & cartilaginous skeleton jaws & matched extremities (balances) scales body work gills for gas trade two-chambered heart; single circle blood dissemination ectotherms generation outer treatment outside advancement in sea-going egg gills body

Slide 18

Humerus Femur Ulna Pelvis Shoulder Tibia Radius Lobe-finned angle Fibula Femur Pelvis Humerus Shoulder Radius Tibia Ulna Fibula Early land and water proficient Transition to Land Evolution of tetrapods

Slide 19

lung buccal pit glottis shut 350 mya frogs lizards frogs Vertebrates: Amphibian Characteristics body structure legs (tetrapods) soggy skin body work lungs (positive weight) & dispersion through skin for gas trade three-chambered heart; veins from lungs back to heart ectotherms propagation outer preparation outer improvement in sea-going egg transformation (tadpole to grown-up)

Slide 20

weathered shell fetus amnion chorion allantois yolk sac 250 mya dinosaurs, turtles reptiles, snakes gators, crocodile Vertebrates: Reptiles Characteristics body structure dry skin, scales, defensive layer body work lungs for gas trade thoracic breathing; negative weight three-chambered heart ectotherms proliferation inner treatment outer advancement in amniotic egg

Slide 21

lung trachea foremost air sacs back air sacs 150 mya finches, peddle ostrich, turkey Vertebrates: Birds (Aves) Characteristics body structure quills & wings thin, empty bone; flight skeleton body work exceptionally effective lungs & air sacs four-chambered heart endotherms multiplication inside preparation outer improvement in amniotic egg

Slide 22

muscles contract stomach contracts 220 mya/65 mya mice, ferret elephants, bats whales, people Vertebrates: Mammals Characteristics body structure hair specific teeth body work lungs, stomach; antagonistic weight four-chambered heart endotherms multiplication interior treatment inward advancement in uterus sustenance through placenta birth live youthful mammary organs make drain

Slide 23

Vertebrates: Mammals Sub-bunches monotremes egg-laying well evolved creatures need placenta & genuine areolas duckbilled platypus, echidna marsupials pouched warm blooded animals posterity sustain from areolas in pocket brief placenta koala, kangaroo, opossum placental genuine placenta supplement & squander channel vixens, bats, whales, people

Slide 24

Vertebrate fast check… Which vertebrates lay eggs with shells? Which vertebrates are secured with scales? What adjustments do winged creatures have for flying? What sort of symmetry do all vertebrates have? Which vertebrates are ectothermic and which are endothermic Why must creatures of land and water live close water? What regenerative adjustments made vertebrates exceptionally fruitful? What attributes recognize the 3 sub-gatherings of warm blooded creatures?

Slide 25

That's the buzz ! Any Questions?
