Human Evolution Jans
| Question | Answer |
|---|---|
| Classification (by thing) | Kingdom, Phylum, Class, Order, Family, Genus, Species |
| Paleoanthropologist | study human evolution (Richard Leaky, Mary Leaky, Raymond Dart) |
| Evidence for human evolution | DNA, skeletal fossils, cultural evidence, protein sequences, mtDNA |
| Animal Kingdom | multicellular, Eukaryotic, ingestive heterotrophs |
| What Phylum are we? | Chordata |
| Chordata | throat pouches, tail beyond anus, dorsal nerve cord |
| Our subphylum? | Vertibrates |
| Our class? | Mammals |
| Mammals | hair, warm blooded, beathe air, 4 chambered heart |
| Our order? | Primates |
| Primates | 5 digits, sensitive flat nails, 3D binocular vision, social |
| 2 types of Primates | Prosimians, Anthropoids |
| Which type of primate are we? | Anthropoids |
| Our family? | homonid |
| Homonid | biped, good climbers, sexual dimorphism, opposible thumbs, large brain |
| Anthropoids evolved into 3 groups? | New World Monkeys, Old world Monkeys, Homonids |
| Hominoid | superfamily (apes + humans) |
| Hominid | family, Homo Sapien only one left |
| Different theories for human migration? | multiregional model and out of Africa model |
| Sahelanthropus tchadensis | mix of ape and human, "toumai", v FIRST |
| Ardipithecus ramidu | mix of human and ape, last common ancestor of chimps and humans, first bipedal, v SECOND |
| Australopithecus afarensis | "Lucy", lactoli footprints, brains same as chimps but more developed, bipedal human like pelvis + leg bones, v THIRD |
| Australopithecus africanus | bipedal, protruding face, v FOURTH |
| Homo habilis | used tools, "Handy Man", culture, v FIFTH |
| Homo erectus | "upright man", used fir and lived in caves, sophisticated tools, "Thinking Machine", carnivores, v SIXTH |
| Homo sapiens neanderthalensis | larger than human brain, robust, 27 DNA differences with modern humans |
| Homo sapiens sapiens: Cro-Magnon | modern human, coexisted with neanderthals, more migration due to ice age, artwork is milestone separating old from new |
| Does evolution happen on demand? | no |
| 2 categories of what creatures become when environments change | specialist and generalist |
| what did the Homo erectus sound like? | a baby |
| what 3 homonids lived simultaneously? | neanderthals, Homo erectus, Homo sapiens |
| stereoscopic vision | 3d vision |
