population genetics and evolution
population genetics
factors that cause the gene pool to change
mutation
changes in alleles
accidents
events unstoppable
earthquake
volcanic eruption
Antarctic ice shifting
artificial selection
human interference
selecting strong genes
breeding
natural selection
survival of the fittest
situations in which natural selection does not operate
abundant growth
no competition
multiple selection pressure
possible die out from missing allele
rates of evolution
could be rapid
few generations
normally takes time
normally observed phenotypically
speciation
phyletic speciation
pollen transfer
full haploid genome
seed deispersal
birds
winds
island rafting
floods
feathers
vegetative propagation
divergent speciation
abiological reproductive barriers
geographic speciation
#
biological reproductive barrier
prevention of gene flow
flower no longer visited
adaptive radiation
rapid changes in species
catalyst
radiation
convergent speciation
species conjoining
like alleles
adaptations
evolution and the origin of life
chemicals produced chemosynthetically
cloud experiment
amino acids
sugars
lipids
nitrogen bases, ect.
conditions on earth before the origin of life
second atmosphere
H2S
NH3
CH4
energy sources
heat from light
gamma
formation of polymers
light energy
absorption of clay particles
aggregation and organization
lipids
on top of water
early metabolism
heterotrophs
absorbing molecules
from the ocean
oxygen
aerobic respiration
rust
lack of could have lead to over oxygenation
death of everything
oxidizing atmosphere
the presence of life
are aggregates alive?
living and nonliving
physics are identical
allopatric
