Is eviromenntal changes drive reprodution a natural selection?
Environment IS natural selection, so a change in environment is a change in selection pressure.
Why is natural variation important when it comes to evolution?
Only in the sense that natural selection needs variations in organisms to select from. Evolution could take place by random processes, such as genetic drift, or geographic processes, such as gene flow, but only natural selection causes the adaptive change that results in speciation.
What is the name of this type of evolutionary change?
Natural selection
What did Charles Darwin call his mechanism of change?
Natural Selection.
What are other evolutionary mechanisms besides natural selection?
A very important mechanism of evolutionary change besides natural selection is geneticc drift.
Is eviromenntal changes drive reprodution a natural selection?
Environment IS natural selection, so a change in environment is a change in selection pressure.
Which of the following is the most powerful evolutionary force in large populations over time?
Only natural selection could be the answer here as natural selection is the main driver of adaptive change leading to evolutionary change and speciation in large populations.
Was it absolutely necessary for natural selection to take place?
Genetic change is necessary for natural selection to take place
Why is natural variation important when it comes to evolution?
Only in the sense that natural selection needs variations in organisms to select from. Evolution could take place by random processes, such as genetic drift, or geographic processes, such as gene flow, but only natural selection causes the adaptive change that results in speciation.
What is the name of this type of evolutionary change?
Natural selection
Can rocks change what they are?
No, but they can be changed by natural process acting on them.
What drives the rate of diversity change?
Natural selection, Evolution, Artificial selection, disasters
What is true about nature selection?
Natural selection usually causes a species to change gradually
Is natural selection a process or a result of a process?
Natural selection is only the result of changing environments, mutation and the variation resulting therein. Natural selection is the process of adaptive change and the main mechanism of evolution that leads to speciation. Natural selection is a process as mutation and variation are grist to the mill of natural selection.
What type of natural selection causes no change in the population?
If a population exists in an environment that changes very little, then natural selection may not provide any pressure to change. However, even under these conditions genetic driftoccurs, introducing random change within the parameters set by natural selection.
Is natural selection a cause of speciation?
Yes. Without natural selection there might probably still be change, but it would produce a fine gradient of diverging morphologies in every 'direction' of change. Natural selection limits the 'directions' of change, thereby producing distinct morphologies and thus distinct species.
What term is defined as natural change that occur in communities over time?
Natural selection
