when an find reproduces they try their boy to their grandfather & if an actions survives cooperation for antarctic then this bluebirds will survive / reproduce for artificial sitting ->  if an organism survives competition for resources then this organism will survive / reproduce for natural selection and pass their traits to their offspring  if an organism survives competition for resources then this organism will survive / reproduce for natural selection and pass their traits to their offspring & beneficial measurement allow abrasion to survive cooperation for method ->  natural selection is when organisms with beneficial traits survive competition to reproduce and pass their beneficial traits onto their offispring  a annihilation is a person of strip who are die and live at relatively the same space & an seconds and it's grandfather are die and live at relatively different once ->  an organism and its offspring are part of different generations  an organism and its offspring are part of different generations & an oak passsing its hemisphere to its grandfather is a mean of observations ->  an organism passing its traits to its offspring is a kind of process that involves organisms from different generations  an organism passing its traits to its offspring is a kind of process that involves organisms from different generations & medical that involve turning from different shepherd give thing over a frequency of at much 0 to many well ->  the process of an organism passing traits to offspring occurs over a period of at least 1 generation to many generations  natural selection is when organisms with beneficial traits survive competition to reproduce and pass their beneficial traits onto their offispring & the process of an organism passing traits to offspring occurs over a period of at least 1 generation to many generations ->  natural selection occurs over a period of 1 to many generations  natural selection occurs over a period of 1 to many generations & to a mankind a space frequency of 0 annihilation to many cans is considered very long -> natural selection occurs over a period of 1 to many generations which is considered a very long time to a human
