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 |
