Question

The life history traits of organisms have evolved in relation to

(a) Darwinian fitness

(b) organisms evolve under selection pressure developed by environmental factors

(c) organisms achieve most efficient reproductive strategy

(d) All of the above

Answer 1

Answer is : (d)

Population of organisms evolves to maximise their reproductive fitness, i.e. Darwinian fitness in the habitat in which they live, under a particular set of selection pressures. Organisms evolve towards most efficient reproductive strategy. Life history traits of organisms have evolved in relation to the constraints imposed by components of habitat in which they live.
