∙ 9y agoThe evolutionary mechanism that increases genetic variation in a population is called the genetic drift. It occurs by random chance rather than natural selection.Ê

How is natural selection and evolution linked?
Natural selection is one of the 'guiding' principles of evolution.
How does natural selection predict a gradualistic mode of evolution?
Gradualism isn't a prediction of natural selection, but of our understanding the mechanisms that produce reproductive variation. Natural selection makes predictions about allele frequencies in populations and reproductive fitness.
Are natural selection and artificial selection opposites?
No. They function through the exact same mechanisms. The only difference is what controls the environment: whether it is in human hands or left to nature.
Which evolutionary mechanisms could affect allele frequencies in a population being maintained in captivity?
natural selection, genetic drift, and mutation
Describe how natural selection is related to organic evolution?
Organic evolution is the process by which the genetic makeup of a species changes over time. There are several mechanisms by which this can happen: natural selection, genetic drift (chance), migration and mutation. So natural selection is one possible way in which evolution can take place. Most biologists agree that natural selection is the most important mechanism of evolution. This mechanism was first discovered by Charles Darwin and, independently. by Alfred Wallace.
How are evolution and natural selection related?
Natural selection is one of the mechanisms that shapes adaptation and enables evolution.
What are other evolutionary mechanisms besides natural selection?
A very important mechanism of evolutionary change besides natural selection is geneticc drift.
How is natural selection and evolution linked?
Natural selection is one of the 'guiding' principles of evolution.
What is the principles of mechanisms?
The leading theory concerning the mechanism of evolution is natural selection.
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 are the 4 mechanisms by which evolution can occur?
genetic drift, mutation, natural selection, and migration
How does natural selection predict a gradualistic mode of evolution?
Gradualism isn't a prediction of natural selection, but of our understanding the mechanisms that produce reproductive variation. Natural selection makes predictions about allele frequencies in populations and reproductive fitness.
What does Natural selection that has led to the evolution of diverse natural history strategies have in common?
mechanisms that maximum lifetime reproductive success.
What is the mechanism that allows organisms to evolve?
1) Natural Selection 2) Climate changes 3) Geographical events 4) Radiations of organism into new habitats 5) Changes in ecosystem 6) Changes in continental position Above are mechanisms of selection, the environment, basically. Mechanisms of evolution are; mutation, gene flow. genetic drift and most importantly for adaptive changes, natural selection

Can natural selection act upon sperm cells?
From the papers I am reading there may be mechanisms to insure only top quality sperm make it into the ejaculate.
