Document Summary

More bodies needing stuff for survival than there is available e. g. food, water, mates: competition for resources occurs among individuals within populations, results in differential survival and reproduction, more poetic way of putting it: in the stuggle for existence and resources (such as food), individuals with favourable biological diversity and traits are more likely to survive and reproduce (reproductive success). And therefore: favourable (heritable) genetic traits are passed onto offspring: if a population is isolated, the passing of these genetic traits (in responding to different selective pressures) can lead to the development of a different species e. g. galapagos finches; strains of bacteria that have become resistant to standard antibiotics; among humans: malaria in plasmodiun faciparum mosquito and sickle cell anemia (greater chance to survive to a reproductive age if carry sickle cell allele and have malaria) and salt retention gene" in african and non african human population.
