| + | ===== evolution of intelligence ===== | ||
| + | Why evolve it? | ||
| + | |||
| + | * predation requires movement and sensory ability | ||
| + | * prey need to avoid being eaten | ||
| + | * our strategy dealing with highly variable environment | ||
| + | * | ||
| + | |||
| + | Artemis was Apollo’s twin sister | ||
| + | |||
| + | ===== Evolution of mammalian groups based on DNA sequences ===== | ||
| + | |||
| + | A quick divergence to mammalian biology | ||
| + | |||
| + | Afrotheria | ||
| + | Atlantogenata | ||
| + | Eutheria | ||
| + | Boreoutheria | ||
| + | Xenarthra | ||
| + | |||
| + | Etc. | ||
| + | |||
| + | Where is intelligence found: | ||
| + | * primates | ||
| + | * dolphins | ||
| + | * afrotheria | ||
| + | * octopus - very intelligent | ||
| + | | ||
| + | Ant eating- convergent | ||
| + | |||
| + | ===== using tools like synthetic biology===== | ||
| + | |||
| + | Or eventually, will we make life de novo? | ||
| + | |||
| + | With engineering we can explore things that might happen elsewhere | ||
| + | |||
| + | Can put things in vesicles now, and they can make proteins. Is that life yet? | ||
| + | |||
| + | Average person thinks big gap is microbes to humans. | ||
| + | |||
| + | So back to the original question: is there a universal biology? | ||
| + | |||
| + | Arguments from convergence seems to indicate yet. | ||
| + | |||
| + | Would aliens look like us? | ||
| + | |||
| + | Divergence - organism using tools in the toolkit | ||
| + | |||
| + | Each divergent uses different toolkits to build the same feature | ||
| + | |||
| + | |||
| + | |||
| + | Last universal common ancestor | ||
| + | * there seems to be a branching very early - distinct metabolically | ||
| + | |||
| + | Question: if you have certain complexity in a molecule, left handed and right handed molecules. | ||
| + | |||
| + | One idea is it was an accident that gets the secondary and tertiary structures | ||
| + | |||
| + | Another idea - bias from circularly polarized light, more of one precursor or the other | ||
| + | * predictive power | ||
| + | |||
| + | Question: interstellar panspermia | ||
| + | |||
| + | Rocks can go from planet to planet. | ||
| + | |||
| + | Announced same day as someone won the nomination for Republican Party. Not a coincidence | ||
| + | |||
| + | Interplanetary exchange between mars and earth is known. | ||
| + | |||
| + | Could you get a life form ejected, survey journey, survive impact | ||
| + | * every step possible | ||
| + | * problem is transit time - long time with no metabolism damage just accumulates - interstellar probably not possible | ||
