Alfred russel wallace
Darwin publish theory of?
On origin on species by means of natural selection in 1859.
note: natural selection in action
-mechanism of adaptation: individual with the most suitable traits "selected": population slowly reshaped.
Austrian monk-spent 7yrs hybridizing pea plants. he discovered way traits passed on.
Genes: units of hereditary information, code for traits
Note: Darwinian-natural selection
gradual genetic change due to:
selective pressure-natural selection, sexual selection.
operates at individual level:
-those with the most suitable traits survive and pass on genes.
incremental genetic changes reshape population(evolution)
Note: Homo habilis or handy man
few Homo habilis fossils show variation in morphology
Note: Homo erectus or Upright man
-Bi-facial hand axe
Note: Homo neanderthalensis
-ice age europe
their cranium: long, low and wide. large nasal aperture. occipital bun.
Note: emergence of homo sapiens arose in Africa.
selective pressure- drove behavioral and social changes.
anatomically modern human-high cranial vault indicates COGNITIVE changes
Means of adaption:
are all homo sapiens migrated from Africa?
Notes: human in the upper paeolithic
40k to 10k in ice age europe
-homo sapiens "cro magnon"
