Question

Close 120% When testing kin-selection theory, we use this holistic measure of an organism's survival and reproductive benefits - - to determine the costs and benefits of cooperating with relatives. Question 23 1 pts Which of these factors most strongly drives the evolution of individual recognition signals in offspring? large number of reproductive attempts per lifetime large number of reproductive attempts per season few mates per breeding bout per individual female large number of offspring raised per breeding bout per group few offspring raised per season per group

Answer 1

Large number of offsprings raised per breeding about the group

The life history of a species is the pattern of survival and reproduction events typical for a member of the species (essentially, its lifecycle).

Life history patterns evolve by natural selection, and they represent an "optimization" of tradeoffs between growth, survival, and reproduction.

One tradeoff is between number of offspring produced and the amount of energy (both physical resources and parental care) put into each offspring.

Timing of first reproduction is another tradeoff. Early reproduction lowers the chance of dying without offspring, but later reproduction may allow organisms to have more or healthier offspring or to provide better care.

Members of some species reproduce only once (semelparity), while members of other species can reproduce multiple times (iteroparity).
