Genetic and Evolution

Theory of evolution
mid 1800's, how the mind works, nonmat­erial mind
Charles Darwin
natural selection and fitness
Natural selection is a theory deveopled through Darwins observ­ations of the fitness of species charac­ter­istics to its enviro­nment
mind = produce of the nervous system
evolution is a slow process
fitness = organisms that are going to survive
natural selection ability for a species to adapt to their enviro­nment, find food and water, and mate in order to stay alive long enough to pass on genetic traits favorable to that setting

First Brain Cell

first brain cell: 700 mya
cell moving towards heat or light
starts getting collection of brain cell to work together and produce basic brain function
first brain cell: 250 mya
first primate brain: 7 mya
 

Evolut­ionary Adaptation

survival adaptation
reprod­uctive adaptation
intras­exual compet­ition
inters­exual selection
obtain food for yourself
passing on genes to the next genera­tions
passing on genes with a greater frequency due to their associ­ation with greater mating success
in this process if member of one sex are attracted to certain qualities in greater numbers, simply because their possessor mate more often
physical traits
some genes less useful, but are needed for reprod­uction
males competing with other males to win female over
female can select the winner
camo
make an animal more desirable to the opposite sex
pressure on males
which one has the better genes/­traits
 
example: peacock lowers their rate of survival but attrack female
not always a physical deal
   
example: satin bird
