Natural selection leads to changes in a population over time as individuals with advantageous traits survive and reproduce, passing those traits to their offspring. If these changes accumulate and lead to reproductive isolation between populations, new species can form through a process called speciation. This can occur through geographical isolation, reproductive isolation, or genetic mutations that create barriers to interbreeding.
What else can I help you with?
Can RNA undergo a natural selection and cause evolution or change?
no
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.
Evolution is the gradual change in phenotype frequency of a species what process causes evolution?
Evolution is primarily driven by natural selection, which occurs when heritable traits that provide an advantage for survival and reproduction become more common in a population over time. Other processes that can cause evolution include genetic drift, gene flow, and mutations. These processes interact to shape the genetic makeup of a population and lead to changes in phenotype frequency over generations.
Is natural selection a cause of evolution?
No, natural selection is believed to result in evolution.
Which mechanism of evolution can cause adaptation?
Natural selection.
Can RNA undergo a natural selection and cause evolution or change?
no
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.
What is the relationship between evolution and natural selection?
Evolution is the process of change in species over time, while natural selection is a mechanism by which evolution occurs. Natural selection acts on genetic variation within a population, favoring traits that increase an individual's chances of survival and reproduction in a given environment. Over time, these advantageous traits become more common in the population, leading to evolutionary change.
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.
What mechanism did Charles Darwin believe caused evolution?
Charles Darwin proposed that natural selection was the mechanism responsible for evolution. This idea suggests that organisms with advantageous traits are more likely to survive and reproduce, passing on those traits to future generations, leading to gradual changes in populations over time.
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.
What is the slow process that results in new species?
The slow process that results in new species is called speciation. This occurs when a population of a species becomes isolated from the rest of its species and over time, genetic mutations and natural selection cause it to evolve into a distinct species. This process can take thousands or even millions of years to be completed.
Can someone help you compare and contrast natural selection and evolution any help would be great?
Evolution is simply genetic change within a poulation. That change can occur in several ways. One is immigration/emigration: individuals moving in or out of a population bring in or take out their alleles with them. Another is genetic drift, or chance events which cause the frequencies of alleles in a population to fluctuate. New mutations can change the allelic frequency as well. Finally, natural selection can cause some alleles to become more common at the expense of others. In short, natural selection is one of several mechanisms that can bring about evolution.
