Natural selection is the driving force for evolution. Evolution was not first proposed by Charles Darwin. There had been many observations found pointing to the idea long before Charles Darwin. His grandfather, Erasmus Darwin, had proposed evolution 75 years before Charles Darwin first Published his book, "On the Origin of Species by Means of Natural Selection or the Preservation of Favoured Races in the Struggle for Life". Before this, it has been thought evolution took place as a conscious effort by species to adapt to their environment. Charles Darwin gave us the driving force to evolution, "Natural Selection". Natural selection needs several things to occur. First, there must be a variation within each species. Second, there must be a high enough Death Rate to prevent the variations which are not well adapted to die before individuals pass their characteristics on to the next generation. A giraffe with a slightly longer neck will survive better and so its offspring will have a slightly longer neck and they will also survive better. Those with slightly shorter necks will find it harder to survive, or will even die, and will not breed so well. In this way, giraffes developed long necks to reach the food they need. The trouble is, there are problems with having really long necks. Blood pressure and supply is one of them so giraffes have evolved a special organ between the blood supply and brain to prevent this. A giraffe's neck has become the ideal length to survive on the plants they eat.
What else can I help you with?
How are evolution and natural selection related?
Natural selection is one of the mechanisms that shapes adaptation and enables evolution.
What is natural selection most closely related to?
Natural selection is most closely related to Darwin's theory of evolution.
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.
What is natural selection How is it related to evolution?
Natural selection is the process of certain animals being more successful than others and thus reproducing more. It is the driving force behind evolution as we currently understand it.
How much natural selection leads to evolution?
All natural selection results in evolution. But natural selection is not necessarily the only mechanism leading to evolution. There are processes at work on a molecular level, such as intragenomic conflict-type processes, that also result in differential reproductive success, but aren't exactly related to the kind of processes Darwin first described.
What is mutation and how is it related to evolution?
A mutation is any change in the DNA. Mutations provide the genetic variation that evolution by natural selection needs to select from.
Which of Darwin's postulates about evolution by natural selection is most directly related to differential reproductive success?
Individuals suited to the struggle for existence will survive and reproduce better than individuals not so suited. Differential reproductive success is just another name for evolution by natural selection.
Is evolution closely related to DNA?
Yes, evolution is closely related to DNA. Changes in DNA, such as mutations, are the raw material for evolution by natural selection. Over time, these changes can accumulate and lead to the development of new species through the process of evolution.
How are organisms related to evolution?
Organisms are related to evolution through the process of natural selection. Evolution is the change in the heritable characteristics of biological populations over successive generations, which occurs as a result of natural selection acting on heritable traits. Organisms that possess advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring, leading to changes in the population over time.
How is directional selection related to the process of evolution?
Directional selection is a type of natural selection where individuals with traits that are better suited to their environment have a higher chance of survival and reproduction. This process can lead to the evolution of a population over time as certain traits become more common in the gene pool.
Where did the theory of natural selection fall short?
It didn't, actually. While natural selection isn't the complete story of evolution, it is the single most important part of it, and all discussions of evolution must inevitably involve natural selection in some form.
Is it malaria related to natural selection?
Yes, natural selection plays a role in the evolution of genetic resistance to malaria. Individuals with genetic traits that provide resistance to the disease are more likely to survive and pass on their genes, leading to a higher prevalence of resistance in populations where malaria is endemic. This evolutionary process is an example of natural selection in action.
