An error sometimes made by beginning biology students is called the "Adaptationist Fallacy" wherin a trait observed in a populat
ion is automatically presumed to be the most beneficial phenotype for that species/population. Why is this presumption not always correct? Describe a scenario where the adaptationist fallacy is incorrect.
The Adaptationist Fallacy can prove very costly to biologist who are assuming it wrong according to the function in the environment. Let us have an example of the phenotype of wheat diploid breed that produces non-bearded grains variety, but we cannot assume it as a beneficial phenotype without further extensive research. After research, we came to know that there is also a major hexaploid bearded variety, that produces more number of grains. That's how, the Adaptationist Fallacy may prove fatal if we have assumed diploid as a major beneficial phenotype.
The chart is a basic molecular design of multicellular organisms.
Atoms, molecules, cells, tissues, organs, organ systems are the building blocks of the human body which combine together on the basis of similar function or structure to achieve various body functions.
Atoms form chemical bonds with other atoms and form molecules.
Molecules combine together to form cells.
Cells are the basic functional and structural units of life.
Cells that perform similar functions combine together to form tissues.
Two or more kinds of tissues that perform similar functions combine to form organs.
Organs, in turn, form organ systems such as the respiratory or cardiovascular systems etc.
