The ‘anticipatory’ behaviors that have been evolved in organisms, such that the organisms use to respond to the events occurring in nature before they actually happen. Introduction: The populations cannot adapt to environmental conditions that have not been experienced by the organisms in a population, in natural selection. Yet, many organisms are able to respond to the events, occurring in their surroundings, even before they actually happen. For example, many birds depart to the southern wintering grounds from temperate zone long before the arrival of winters. Similarly, some mammals hibernate even during the warm conditions.

If natural selection has no foresight,how can it explain features that seem to prepare organisms for future events? For example, deciduous trees at high latitudes drop their leaves before winter arrives, male birds establish territories before females arrive in the spring, and animals such as squirrels and jays store food as winter approaches.

Natural selection occurs when which of the following conditions are met? Group of answer choices a.Variations between individual organisms lead to differential survival chances. b.The conditions in an ecosystem support a wide range of living organisms c.Individual organisms depend on each other to obtain available resources. d. Habitat and nutrient resources in an area are plentiful over a long period of time.

Modern humans over-eat sugar because we love it so much. One might ask, “why are we designed by evolution to love sugar when sugar is so bad for us?” How does the concept of the “environment of evolutionary adaptation” (EEA) help us explain this and some otherwise puzzling behaviors of modern humans? Please explain EEA first.
