What is Interdemic selection?
What is Interdemic selection?
Definition: A type of natural selection which acts upon populations within a species. Interdemic selection occurs when populations die out or give rise to new populations at different rates, depending on whether they have traits that are beneficial or harmful to the population as a whole.
How does the concept of Interdemic selection inform our understanding of social insects?
How does the concept of interdemic selection inform our understanding of social insects? It shows how “altruism” behaviors can evolve because the colony is the true unit of selection.
What is meant by the concept of species selection?
Species selection is the process responsible for the proliferation of species that have lower extinction and higher speciation rates. Species selection is a reason why macroevolution and microevolution may be uncoupled.
What is Deme in taxonomy?
deme, in biology, a population of organisms within which the exchange of genes is completely random; i.e., all mating combinations between individuals of opposite sexes have the same probability of occurrence.
Which group of organisms has the most species that have been named and described?
Insect species represent the largest percentage of the world’s known species. Beetles make up about one-third of all known insect species. If we look at your question from the point of view of numbers of individuals, the answers is almost certainly insects as well.
Which example shows genetic variation in a species?
An example would be moths of the same species with different color wings. Moths with wings similar to the color of tree bark are better able to camouflage themselves than moths of a different color. As a result, the tree-colored moths are more likely to survive, reproduce, and pass on their genes.
What are r selected species?
r-selected species, also called r-strategist, species whose populations are governed by their biotic potential (maximum reproductive capacity, r). Such species make up one of the two generalized life-history strategies posited by American ecologist Robert MacArthur and American biologist Edward O.
What is an example of a deme?
It is to such clusters that the term deme is usually applied. Thus, the green frogs in an isolated pond, a town of prairie dogs, or a field of wild sunflowers might be examples of demes.
What is kin selection example?
Kin Selection in Social Insects The honeybee and other social insects provide the clearest example of kin selection. They are also particularly interesting examples because of the peculiar genetic relationships among the family members. Male honeybees (drones) develop from the queen’s unfertilized eggs and are haploid.
What is kin selection in social psychology?
Kin selection occurs when an animal engages in self-sacrificial behaviour that benefits the genetic fitness of its relatives. The theory of kin selection is one of the foundations of the modern study of social behaviour. British evolutionary biologist W.D.
