Students fail to recognise that natural selection refers to changes in the distribution of certain traits at the population level, the collective, resulting from interactions between individual organisms and their environment at the next lower level in the system. Processes like selection are emergent ...
constrains on nature selection Constraints on Nature Selection Introduction •Nature selection refers to the process by which the environment, through various mechanisms, determines which traits are advantageous and allow organisms to survive and reproduce. •However, there are certain constraints that ...

Conversely, group selection refers to the idea that natural selection sometimes acts on groups of organisms as a whole. This results in the evolution of traits that may be disadvantageous to individuals, but advantageous to the group. As Darwin put it, “A tribe including many members who… ...
In reference to natural selection, what selective pressures cause the change in the organisms' gene pool? Gene pool The gene pool of an organism refers to all the genes found in every individual of an existing population. The size of the gene pool can influence...
Therefore, being 'fit' only refers to special prevalent conditions. In each generation the individuals thus being 'unfit' will be eliminated together with the 'unlucky' ones. All other individuals will survive and reproduce, notwithstanding their properties. Hence, natural selection results in the '...
Theory shows how sexual selection can exaggerate male traits beyond naturally selected optima and also how natural selection can ultimately halt trait elaboration. Empirical evidence supports this theory, but to our knowledge, there have been no experime
This is where one of the bestnatural selection examplescame into play. Some species of fish that lived near the coast developed a strange mutation: the ability to push themselves along in the mud and sand on the shore with their fins. ...
