The fitness of a variant is expressed in terms of the average number of offspring.
Theory of evolution by natural selection. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms. That simple.
The theory of evolution by natural selection. Evolution is a fact explained by the theory. Short explanation. Natural selection is the nonrandom survival and reproductive success of randomly varying individuals.
Adaptive change is the province of natural selection and natural selection is one of the main drivers of evolution. Natural selection selects from the individuals variations in a population of organisms on, basically, reproductive success and this adaption is passed on to progeny which changes the allele frequency in the population which is evolution.
mechanisms that maximum lifetime reproductive success.
Darwin developed The theory of evolution by natural selection.So, to answer you question, all of it!You need to make a distinction between evolution, the change in allele frequency over time in a population of organisms, and natural selection, the nonrandom survival and reproductive success of randomly varying organisms. Natural selection is the main driver of evolution.
A simplified explanation. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms who by this reproductive success change the allele frequency over time in populations of organisms, which is evolution.
Theory of evolution by natural selection. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms. That simple.
Natural selection is most closely related to Darwin's theory of evolution.
The theory of evolution by natural selection. Evolution is a fact explained by the theory. Short explanation. Natural selection is the nonrandom survival and reproductive success of randomly varying individuals.
Differential reproductive success of variant replicators.
It wasn't! The theory of evolution by natural selection has nothing to do with social Darwinism and to posit such a connection is ill posed. The theory of evolution by natural selection is about individual selection of organisms and has nothing to do with group to group success in economic terms.
Adaptive change is the province of natural selection and natural selection is one of the main drivers of evolution. Natural selection selects from the individuals variations in a population of organisms on, basically, reproductive success and this adaption is passed on to progeny which changes the allele frequency in the population which is evolution.
Darwinian evolution is descent with modification and natural selection, or, in other terms, reproductive variation and differential reproductive success.
mechanisms that maximum lifetime reproductive success.
The book, On The Origin Of Species, " suggested " that organisms evolve through the process of natural selection. The nonrandom survival and reproductive success of randomly varying organisms

Individuals suited to the struggle for existence will survive and reproduce better than individuals not so suited. Differential reproductive success is just another name for evolution by natural selection.
