Chapter 10 : The Origins and Diversification of Life on Earth

classification MARKERS for MNEMONIC Perissodactyla=odd toes rhino tapir; even=deer/pig, hippo/whale. Order PRIMATES Family Hominidae
Equidae: horse (E. ferus), donkey, zebra! Aristotle genera: Plants/blood animals: mammals, reptiles, birds, whales, fish. Binomial.
speciation-allopatric SPECIATION means how arise? Certhidea olivacea warbler-finch; dull-colored grassquit (tanager)
speciation-sympatric strawberries, oysters, cotton, cacoa; Tragopogon=goatsbeard SUNFLOWER family Triploid Watermelon: artificial selection with Colchicine Triploid Oysters Tragopogon: Understanding the evolution of polyploidy Polyploidy everywhere 3:00-4:40 sugar cane, banana, cotton, cacoa, wheat, strawberry; oysters
tree Video exercise is from PHELAN. APPEARANCE deceiving! How are ancestors related to Linnean levels? TRICK q: bird & mammal=tetrapods 4 limbs!
phylogeny Phylum Chordata -> Class Mammalia; milk must have 4 legs, can lose legs! I have white hair.
HAIR; keratin/skin. Humpback bumps tubercles -> follicle sweat/sebaceous glands, nipples.
WHALE is a mammal, sings. Milk: prolactin; oxytocin let-down. Explore the tree of life PBS-YourInnerFish InnerMonkey 43:10 3 month-old Pig-tailed Macaque Monkey object permanance: human long childhood
clade Bring BIRD skeleton in 1305. Gotta invite all to reunion! Reptiles + turtles, snakes. Archaeopteryx the feathered dinosaur grows like a dinosaur, not a bird
analogous Afrotheria 100 MYA in Africa - I just learned myself of THIS convergent example.
BIOGEOGRAPHY where do Asian elephants come from (Forest/Savannah)? Mammoths had MOLARS like bats; Beringia 15 KYA. Asian-American Land Bridge (Beringia) - for mammoths and humans
domains No PROKARYA; 3.6 BYA (Earth 4.6) MAP animals! What's WRONG with picture? 3 Protists!
Play Phelan video on micro/macro evo -> Woes rRNA domains, horizontal gene transfer, viruses
