If a population of organisms could not react to their physical environment, what would that mean for the concept of natural selection?

The strongest selection in most cases was not for size, but for age of maturity. Guppies under lower predation tended to mature later, and size was sometimes even negatively selected...

Ecosystem is an ecological unit, which consists of a biotic community together with its environment. In the study environment this concept helps to determine remote consequences of a certain activity...

Cannibalism and Natural SelectionIntroduction Also known as anthropophagy, cannibalism is a term that describes an occurrence where a member of a certain species eats another member of the same species....

The fundamental forces behind evolutionary change through natural selection are differences in survival and reproduction among individuals. In many species of animals and some plants differences in reproductive success can...

Kin selection is altruism that helps to increase a relative's fitness and consequently the individual's own fitness. Group selection is a process where an individual's detrimental behavior is beneficial to the population.

Natural selection can maintain balanced polymorphisms. A balanced polymorphism is one in which two or more phenotypes are maintained in fairly stable proportions over many generations. Natural selection preserves balanced...

Yes, you can. This is because every organism in the world is the product of an evolutionary process.

Selection aspects include: offspring from large litters, brilliant muscles and back fat readings. Similarly, reaching adult size by 1 year of age, with no genetic defects, as well as medium...
