For evolution by natural selection to occur, there must be genetic variation within a population, some of which must be heritable. The environment must exert selective pressure on the individuals, favoring those with advantageous traits that increase their chances of survival and reproduction. Over time, these advantageous traits will become more common in the population due to differential reproductive success.

What is the name for the process where the organism best adapted to their environment to survive?
The process is called natural selection, where organisms that are best adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation.
What proof do we have evolution taking place?
Evidence for evolution includes the fossil record, comparative anatomy, molecular biology, and observed instances of natural selection. These different lines of evidence all support the concept of biological evolution occurring over time.
How can evolution be influenced by natural selection?
Evolution is the change in allele frequency over time in a population of organisms. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms. So, if an organism is selected by having greater reproductive success than it's conspecifics this organism will leave descendents that have the traits for this success and if enough descendents start making up a greater bit of the population then genes( alleles ) will change in frequency and evolution will take place. Natural selection is also the driver of adaptive change leading to speciation.
How does natural selection break h-w assumptions?
One big Hardy-Weinberg assumption is that there is no mutation taking place in the population of interest. Mutation and selection lead to evolution, which the Hardy-Weinberg assumption also does not allow in a population. So, if there is the variation brought about by mutation then there is a chance of natural selection happening and this violates Hardy-Weinberg assumptions.
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 place was Darwin's Theory of Evolution?
natural selection
What did darwin call the process by which evolution takes place?
The book, On The Origin Of Species, " suggested " that organisms evolve through the process of natural selection. The nonrandom survival and reproductive success of randomly varying organisms
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.
Do evolutionists believe in natural selection?
" Evolutionists? " Believe in? " Two words/phrases that are ideological in nature and have no place in a scientific discussion. Evolutionary scientists accept the overwhelming and convergent evidence for the theory of evolution by natural selection. This is the best explanation we have for the adaptive changes seen in evolution.
Why is time an important factor in the process evolution by natural selection?
Because natural selection only preserves incremental beneficial traits to the organism and many different areas of the organism are undergoing mutation and natural selection at the same time against the backdrop of the immediate environment. If a population of organisms, subject to allele change due to natural selection, is not in a changing environment, or split in a allopatric event, then adaptive change will be very slow, or will not happen at all and selection will winnow those variants and stabilizing selection is taking place. Regression to the mean of phenotype.
What is the name for the process where the organism best adapted to their environment to survive?
The process is called natural selection, where organisms that are best adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation.
Was it absolutely necessary for natural selection to take place?
Genetic change is necessary for natural selection to take place
How is evolution taking place in antibiotic and bacteria?
This may not be the answer you're looking for exactly, but evolution doesn't exist. Maybe the organisms have changed slightly over time (natural selection) but they did not completely evolve. God created them as they are.
What proof do we have evolution taking place?
Evidence for evolution includes the fossil record, comparative anatomy, molecular biology, and observed instances of natural selection. These different lines of evidence all support the concept of biological evolution occurring over time.
How and why does natural selection drive the evolution of eukaryotes?
It is often believed that species evolve to become better and become an ultimate organism.This is a misconception. Evolution becomes parallel and takes place simultaneously in different species. Evolution may also be continuous mutation. Evolution takes place simply to ensure better survival in the current habitat.
Where did natural selection take place?
Everywhere where there is life.
Is Genetic diversity is the raw material for evolution?
Mutations occur randomly, and every once in a blue moon, a mutation offers some benefit to a individual of a particular species in a particular place and allows that individual to have more offspring than its peers. If the mutation provides enough benefit to some individuals, they will have a tendency to survive and reproduce (as per the principle of natural selection). Natural selection reduces variability by killing off less fit individuals. It is mutations that increase the variability and allow evolution (successful natural selection, not mass extinction, but controlled deaths) to occur. Without variability there is no evolution.
