Which of the following is not a requirement for natural selection?

a.individuals in the population with different traits


b. genetic inheritance of traits


c. an environment unable to support all the potential offspring of a population


d. shared characteristics


e. a constrained population size





I think it is d, but I'm not sure.

Which of the following is not a requirement for natural selection?
I say D or E both seem correct but I would choose E because natural selection is survival of the fittest so it would require a huge population.
Reply:It is difficult tosingle out any of these factors as being not responsible for natural selection. All these factors to more or less degree assist inthe process.Unless there are individuals with different straits there would be a dominant straits which make one species fitter for living and others lacking it liable to slowly dieing out. The inheritance of such straits is essential for the contiunance of initially existing or acquired straits. If the environment was salubrious for supporting all the potential offspring- e.q. wider space, adequate food etc. even for the comparatively weaker sections all the species would have survived and the only contigency of their extinction would have been their dying out or being killed by others creatures or natural disasters.An environment unable to support all would be a prerequisite of weakers dieing out. Then shared characteristics is a requirement for communal survival e.g. flocks of wolves out for hunting. Last but not least unless there were to be constraint on population size God would have been in Heaven and all would have been right with the Garden of Aden.In short all these factors contribute to evolution and hardly any one of them could be single out as superfluous., though the contribution of each factors would less or more.





If there were no Garden of Aden,and if there was not the Tree of fruit bearing Knowledge tree, neither Adam nor Eve and last but not least not The Serpent there was have been no Exodus ,no Christ, no Bible.
Reply:d, maybe e but not a b or c
Reply:i also believe d. im sure its not a b or c though.





it cant really be c, because if there is no competition, all the population has equal chance of survival, which means that no traits are really needed.
Reply:Its D and E. Natural Selection is a process by which environmental pressures "select" the most fit individuals in a population by making them the most able to survive and have offspring. Thus a is required, to ensure that some individuals are different in a way that my confer survival advantage. Genetic inheritance is also required (so b is out), and competition between individuals for finite resources (so c is out).





e is a difficult one. The way its worded, it would appear required, but its not. All that is required for natural selection is competition for natural resources. The most fit will be the most able to exploit the available resources; their genes will be "selected" because they will be the most likely to have offspring that survive. There is no need for "constraint" of the population size; although as they become more and more successful, and the population grows, they may deplete the resources they need to survive, and then start to die off.
Reply:i just took a bio test that i kicked *** on, so i can 100% say that the three requirements for natural selection are:





trait must be heritable





trait must vary





trait must confer differential reproductive success.





so i'm gonna have to say E.
Reply:Funny we used to jokingly say " natural selection" when some one did something soooo stupid. natural selection is the process of favorable traits becoming prominent while useless traits become weeded out. I believe it is c.
