TV-Guide. com. web about each specific episode and the topic it covers. Lecture 10 - Kingdom Animalia: Vertebrate Phylogeny and Diversity 1.5 lectures I. Phylum Chordata A. Characteristics (Fig 34.1) 1.

Notochord 2. Dorsal, hollow nerve cord 3. Pharyngeal slits 4. Muscular postnatal tail.

Protochordate 1. Cephalochordate - Lancets (Fig 34.3) a. Adults - chordate characteristics persist b. Filter food through pharyngeal slits 2. Urochordata - Tunicates (Fig 34.2) a. Larvae - have chordate characteristics b.

Adults - sessile filter feeders, lacking some chordate characteristics (no post anal tail, notochord, spinal cord) C. Vertebrata 1. Vertebrae - segmented cartilaginous or bony protection around the nerve cord (spinal cord) 2. Greater cephalization a. Skeleton includes cranium and vertebral column i. replaces notochord as main axis of body ii. may be bone or cartilage b.

Support greater mobility and activity II. Chordate / Vertebrate Phylogeny (modify Fig 34.6) A. Split #1 - bearing or lacking vertebrae 1. Lacking - protochordate's (Urochordata &) 2. Bearing - vertebrata B. Split #2 - bearing or lacking jaws (Fig 34.8) 1. Lacking - ag nathans (lampreys) 2. Bearing - all other a.

Jaws evolved from gill arch skeletal elements. Split #3 - bony or cartilaginous skeleton 1. Cartilagenous - 2. Bony - all other. Split #4 - fins or limbs 1. Fins - Osteichthyes (bony fishes) 2.

Limbs - tetrapods a. Evolution - from lobe finned fishes, tetrapod condition may have evolved prior to lungs (Fig. 34.14) E. Split #5 - bearing or lacking an amnion 1. Lacking - amphibians a. eggs lack shells b. Gas uptake and water remove is accomplished at the interface of the water and the egg 2. Amnio tes - all other (Fig. 34.17) a. Shelled eggs or placenta b.

Extra-embryonic membranes - form from embryo side of egg - eliminate wastes and carry out gas exchange. Amnion- one of the extra-embryonic membranes, surrounds the embryo in a fluid buffer, keeps it moist and acts as a shock absorber. F. Split # 6 - scales (& feathers) vs. hair 1. Split within reptiles 2. Reptiles, birds, dinosaurs - scales &/or feathers - which are modified scales 3. Mammals - hair. Vertebrate diversity (good summary in Table 34.1) - each trait only mentioned at the level at which it first appears, unless so noted, the trait exists in following groupsA.

Ag nathans - hagfish es and lampreys 1. Characteristics a. Lacking jaws 2. Groups a... lampreys. Chondrichthyes 1.

Characteristicsa. Jaws b. Cartilagenous skeleton c. Multiple gill slits 2. Groupsa. sharks - fusiform b. skates and rays - dv compression, adapted to life on the bottom. Osteichthyes - primitive and advanced fishes 1.

Characteristicsa. Bony skeleton b. Fins. Operculum covers gill arches 2. Groupsa. Ray finned fishes - perched, trout, tuna, eat. b.

Lobe finned fishes i. Lungfishes - bearing a lung, but lacking strong fins ii. Coelacanth - lacking lung, bearing strong fins. Amphibia 1. Characteristicsa. Eggs are unshelled - tied to water.

External fertilization - tied to water. Some entirely aquatic (bearing gills and limbs) 2. Groupsa. Salamanders - walking movement is undulatory, similar to fish swimming. Frogs and toads i. Most effective terrestrial locomotion ii.

Metamorphosis of tadpole tied to water. Tadpole very fish-like: gills, tail, no limbs c. Caecilians - snake like amphibians - lacking limbs. Reptilian 1.

Characteristicsa. Amnionic, shelled eggs b. Scales containing keratin c. Internal fertilization d. Cold blooded 2.

Groupsa. Turtles - protected by shell, very little change over time. Lizards and snakes i. Lizards - most small, ectothermic, not as active or lg. as dinosaurs ii. Snakes - evolved from burrowing lizards c. Crocodiles and alligators i.

Large, predatory, confined to warm climates F. Aves 1. Characteristicsa. Reptilian characteristics: amnionic eggs, scales on legs. Feathers - adapted scales, perhaps originally as insulation. Light, honeycombed bones. Adaptation to make them lighter i.

Honeycombed bones ii. Reduced organ systems (only one ovary) . No teeth. Endothermic - warm blooded, metabolic rate important to flying 2.

Groupsa. Flightless - walking & swimming. Flying. diving & swimming ii. carnivore, insectivore, herbivore, nectar feeders, etc. Mammals 1. Characteristicsa.

Hair - not modified scales, mammals diverged from reptiles very early. Endothermic c. Lactation. Tooth differentiation 2. Groupsa. Montre me - echidna, platypus i.

Egg layers ii. Maintain other characteristics (lactation & hair) b. Marsupial - op possums, kangaroos, koalas, tasmanian wolf, etc. i. Young born early in development ii.

Crawl to pouch to finish development during lactation. narrow pelvic opening b / c young born small / immature iv. Convergent evolution of forms common (echidna and spiny anteater, wolves, etc.) c. Eutherian (placental) - all other. No egg, prolonged internal maturation ii. Have a placenta, special organ that connects fetus to mother. Wide pelvic opening b / c young born mature iv.

Eutherian diversity - Orders of placental mammals - Table 34.2 (1) Artiodactyl a - even toed (sheep, deer hippos) (2) Perisodactyla - odd toed (horse, rhino) (3) Proboscoidea - long nose (elephant) (4) Edentata - have no teeth (sloth, anteater, armadillo) (5) Rodentia - chisel-like growing front teeth (squirrel, beaver, rats) (6) Insectivore - insect eating (shrews, moles) (7) Lagamorpha - designed for hopping, incisors not growing (8) Chiropteran - flying mammals (bats) (9) Cetacean - fish-shaped bodies, no hind limbs, carnivores (dolphins, whales) (10) Sirena - herbivores, no hind limbs (sea cows, manatees) (11) Carnivora - pointed canines, carnivorous (dogs, bears, cats, weasels, otters, seals, walruses) (12) Primates - opposable thumb, well developed cortex, omnivorous (monkeys, apes, man).
