Can RNA undergo a natural selection and cause evolution or change?
no
Does natural selection cause variety of life on earth?
Yes, natural selection causes evolution, which results in the variety of life on earth.
Is adaptation a cause of natural selection?
No, it's exactly the other way around: natural selection causes adaptation.
Why does polyploidy not cause speciation or even be associated with speciation?
Actually it is.
What are the advantages and disadvantages of natural selection to an organism?
Natural selection can help creatures adapt to their enviorment. Sometimes this can cause unwanted problems.
Is natural selection a cause of evolution?
No, natural selection is believed to result in evolution.
What is the relationship between evolution and natural selection?
Natural selection is one force that can lead to evolution.natural selection is one cause of evolution
Which mechanism of evolution can cause adaptation?
Natural selection.
Can RNA undergo a natural selection and cause evolution or change?
no
What mechanism did Charles Darwin believe caused evolution?
Natural Selection is what Darwin believed was the cause of evolution.
Does natural selection cause variety of life on earth?
Yes, natural selection causes evolution, which results in the variety of life on earth.
How does natural selection and variation help cause evolution?
because the rocks are pretty
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.
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.
How do variation and natural selection work together to cause evolution?
They help each other by gradually accumulate in a species, while unfavorable ones may disappear. Over a long time, natural selection can lead to changes.
How may natural selection be able to cause evolution to occur?
By selecting the variant organism most suited to the environment the alleles of the population then change in frequency over time and thus evolution occurs.
What mechanisms of evolution appear to cause speciation?
Only natural selection appears to cause the adaptive change that can lead to speciation.Answer 2There are various different sets of circumstances that could lead to speciation. This is one example: consider two populations of the same species that are permanently separated from one another through some geographical happenstance. Both populations will experience genetic drift. And since genetic drift is (limited by natural selection, but still) essentially random, these populations will start to diverge - first genetically, and eventually behaviourally and anatomically. If enough time passes, these populations may have become so different from one another that even if they were put back together again, they would not (be able to) produce fertile offspring between them. At this point, speciation has occurred.
