|
Definition
kingdom phyla class order families genus species
every single life form can be categorized
categories are NONCHANGING
humans were put into "animal" kingdom |

|
|
Term
| darwins premises of natural selection |
|
Definition
theres variation within living pop #'s
variation can be inherited from parents
organisms tend to overproduce
theres a struggle for survival
only the fittest survive
over time there will be an accumulation of favorable traits that will lead to a new species |

idea of survival of the fittest
believed that pop. increase our resources dont ..etc
only intellectual ppl should be allowed to survive
sterlization of poor and insane |

SCIENTIFIC ARGUMENT about behavior and reproductive capacity
large group of organisms that have similarities
must be able to reproduce
DEF: A NATURALLY INTERBREEDING POPULAATIOIN CAPABLE OF PRODUCING VIABLE OFFSPRING
species CAN change over time |

| ppl are dying at dif rates bc too much pop,too little resources, threfore theres a struggle for survival |

Term
| imp concepts of natural selection |
|
Definition
n.s. is capable of changing over time
ns works upon phenotypes of individuals, which in turn affects the proportion of alleles within the gene pool
ns cant introduce new alleles into a pop, it can only remove alleles |

Definition
| happen independently of eachother |
|

Term
|
Definition
chnges in frewquency of alleles over time within a pop(ev olution) due to migratio or due to exchanges of alleles between populations
HAS NOTHING TO DO WITH NATURAL SELECTION |

passed to offspring
becomes more numerous due to gene drift |

Definition
at least 1% of pop
start as individual, but through gene drift and natural selection this spreads to over 1% of pop |
|

Term
|
Definition
random changes in the frequency of alleles over time within a population due to CHANCE(happens more in small pop and profound change happens)
(cant introduce new alleles, only take out) |

acting on individual
selects for "advantageous" phenotype
measured by individuals reproductive success |

through ns, changes take place gradually ovevr time
BUT its not the only way change takes place...it can take place quickly thorugh punctuated equilibrium (the pace and pattern that evolutoinary change might take) |

Definition
(kin selection)
many behaviors denying explanation
behaviors that are harmful for individuals, but better for group relies upon selectipon of families rather than individuals
notion of selfish genes (sacrificing urself is selfish cuz ur saving others juss like u)
(this is against darwin's ns) |
|

Term
|
Definition
probability that a gene in 1 individual will occur in another
mom-> .5-> 50%
grandparent-> 25%
sister -> 50%
(specific allele is all or nothing so allele is guestimated at 50%) |
