What is the only evolutionary mechanism that consistently leads to adaptive evolution?

Natural selection
Because natural selection has a "sorting" effect, it consistently increases the frequency of alleles that improve the match between an organism and its environment.

Natural selection is the only mechanism of evolution that will lead to?
Adaptive change and speciation.
What is the evolutionary concept that those with adaptive genetic traits will live and reproduce?
Natural selection, a theory by charles darwin
What is the radiant evolution in Darwin's theory?
Better known as "adaptive radiation", it is independent evolution from a population of a species that has become geographically isolated from its parent population.
The bodys most specific defense mechanism is the what?
The adaptive or specific defense mechanisms: lymphocytes, antibodies, and macrophages.
Evolution is the gradual change in phenotype frequency of a species what process causes evolution?
Mutation, genetic drift, gene flow and the driver of adaptive change, natural selection.
What process is a mechanism of evolution?
Natural selection is a mechanism of adaptive change in evolution.
The mechanism of evolution is?
The main mechanism of adaptive change is natural selection. There are other mechanisms of evolution though Google ' mechanisms of evolution. '
What is the mechanism of Darwin's proposed theory?
The mechanism and main driver of adaptive change in evolution is natural selection.
Natural selection is the only mechanism of evolution that will lead to?
Adaptive change and speciation.
What is the mechanism of evolution?
The main driving mechanism of evolution is natural selection. Though genetic drigt and gene flow can also cause evolution.
Evolutionists often make the distinction between evolution as a fact and evolutionary theory What does this mean?
Evolution is descent with modification. Or, change over time. And formally as the change in allele frequencies over time in a population of organisms. This is an observed and a observable fact. The theory is; the theory of evolution by natural selection, which explains the fact of evolution. Natural selection is the main mechanism ( there are others ) that drives the adaptive change in organism that can lead to speciation, or just simple evolution.
What theory is concerned with the adaptive value of behavior and its evolutionary history?
Ethology
Do evolutionists believe in natural selection?
" Evolutionists? " Believe in? " Two words/phrases that are ideological in nature and have no place in a scientific discussion. Evolutionary scientists accept the overwhelming and convergent evidence for the theory of evolution by natural selection. This is the best explanation we have for the adaptive changes seen in evolution.
Evolutionary psychologists emphasize that environmentally adaptive behaviors are those that have promoted?
Environmentally adaptive behaviors are those that have promoted reproductive success.
Divergent evolution is also known as?
Adaptive radiation
Compare and contrast natural selection and evolution?
Natural selection is the most powerful driver of evolution and it is the only mechanism of evolution ( genetic drift and gene flow are two other mechanisms ) that leads to adaptive change. Natural selection is the nonrandom survival and reproductive success of of randomly varying organisms. Evolution is the change in allele frequency over time in a population of organisms.
How is adaptive radiation and convergent evolution similar?
They both employ the same mechanism: adaptation. The difference is that in one case, subpopulations diverge to adapt to differing circumstances, and in the other, separate species adapt to similar circumstances.
