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.

How did Darwin's theories differ from his predecesors?
By proposing a mechanism for evolution, natural selection, that explained much better than his predecessors how evolution came and comes about.
Is it true that there is no variation between racial and gender groups when it comes to sexual activities?
No it is not
What is hardy weinberg law about?
The Hardy-Weinberg law is about, basically, the constraints on evolution. Small population size, not gene glow, no natural selection and so on. This leads to no evolution, but is not seen in the wild. It is a metric for measuring whether evolution takes place by having such artificial constraints. This polynomial comes out of the law. p2 + q2 = 1 and determines allele frequency change/amount. Google Hardy-Weinberg.
Is there more information for or against evolution?
On almost a monthly basis, more data comes to light in the form of new fossils and other finds, that further support the Theory of Evolution.Charles Darwin (1809-1892) was not the first to study evolution, but he developed the Theory of Evolution by Natural Selection after observing the evidence for evolution during his voyage in HMS Beagle, and followed up by decades of research. This theory says that species evolved over time in response to changes in the natural environment, and was seen by scientists as the best explanation for the facts.There is ample evidence of the transition from one species to another, demonstrating that evolution really did occur. Conversely, there is no real evidence that evolution has not occurred. Those who debate the facts of evolution are left with unsupported hypotheses, often claiming that the world is too young for evolution to have occurred, or that the Laws of Thermodynamics disprove the theory. A third viewpoint is offered by a minority of creationists, such as Willian Dembski. As a qualified scientist, he accepts the immense age of the earth and the reality of evolution, but believes that there may be natural systems that cannot be explained entirely in terms of natural causes and that exhibit features characteristic of intelligent design.For more information, please visit: http://christianity.answers.com/theology/the-story-of-creation
What is the mechanism for determining evolution of life?
The mechanism for determining evolution of life were fossils, egg, scales and footprints. Most of the knowledge comes from fossils. They tell us about the shape and size of that animal.
What is variation in evolution?
A variation of a gene is called and allele. Different alleles are caused by mutations.
What comes first mutation or natural selection?
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
How do paleontologists help with evidence of evolution?
Palaeontologists uncover, examine, categorize and publish about fossils. An important part of what we know of the natural history of life on Earth comes from fossil evidence.

Who invented natural selection?
Evolution is what happens when organisms reproduce with variation of traits, and those variant traits are inherited by further offspring. It is the observed effect of the differential reproductive success of variants. Therefore, in order to have evolution, one single condition needs to be met: that autonomous replicators exist that reproduce with variation. The question therefore becomes: where did life originate from?
What does Victreebel evolve on HeartGold?
Victreebel does not have an evolution. It is the second and final evolution of Bellsprout. Nothing comes after Victreebel.
Are you in favor of Darwin's theory of evolution?
It does not matter to the truth whether I am in favor of it or not. The theory of evolution by natural selection is not only no longer Darwin's it is supported by myriad line of converging evidence and explains much about the fact of evolution. No other explanation comes close. The question is ill posed and smacks of religious thinking that does not understand science or even logical analysis.
Why is evolution important in biology?
As far as scientific investigation has been able to determine, evolution is the means by which life as we know it has come about on our world. It is the fundamental process which underlies all of biology.
Is it true that there is no variation between racial and gender groups when it comes to sexual activities?
No it is not
Is hair color continuous or discontinuous variation?
Hair colour is continuous because there is a continual range of values when it comes to hair colour
