Question

A pied kingfisher in its first year of life helps in the feeding of three full siblings who would not have made it without the helper's efforts. in this first year the bird does not raise any of its own offspring. in the second year of its life the pied kingfisher mates and raises two of its own offspring. after the first two years, what is the inclusive fitness of the pied kingfisher?

Answer 1

The correct answer is 2.5.

Inclusive fitness is the number of "offspring equivalents" that an animal raises or helps survive (we use the term "offspring equivalents" because they don't necessarily need to be offspring, as seen with the bird's siblings). Since this bird helps raise 3 siblings in the first year and 2 children in the second year, its offspring equivalent is 2.5 (.5 per sibling and offspring).

Answer 2

Inclusive health is the sum of the equivalents of ancestors maintained because they do not need to be species like their siblings. Kingfisher birds help care for 3 siblings in the first year, and 2 children in the second year, the equivalent species is 2.5 or 0.5 per breed.

Further Explanation

In evolutionary biology, inclusive fitness is one in every of two metrics of evolutionary success as defined by W. D. Hamilton in 1964:

Personal fitness is that number of offspring that a personal begets (regardless of who rescues / rears / supports them)

Inclusive fitness is that the number of offspring equivalents that a personal rear, rescues or otherwise supports through its behavior (regardless of who begets them)

An individual's own child, who carries one-half of the individual's genes, is defined together offspring equivalent.

From the gene's point of view, evolutionary success ultimately depends on let alone the most number of copies of itself within the population. before Hamilton's work, it absolutely was generally assumed that the genes only achieved this through the amount of viable offspring produced by the individual organisms they occupied. However, this overlooked a wider consideration of a gene's success, most clearly within the case of the social insects where the overwhelming majority of people do not produce (their own) offspring.
