The Lenski experiment with Escherichia coli is a classic here. Over twenty years natural selection selected a bacterium that could digest citrate, something wild type E. coli can not do, with the usual random mutation and selective process going on against the immediate environment. Google Lenski experiment.
What else can I help you with?
Natural selectionwhat are some of the similarities and differences between artificial and natural selection?
Natural selection is more efficient ad more precise.
What are some natural selection for deer?
Natural selection will see to it that genes from the strongest and more fertile bucks and does are passed down susequent generations.
Some science expirements for children?
Why don't you do a egg in a bottle?It is a very easy thing to do.
How natural selection help few species to survive and how few others got extinct?
how natural selection help some species to survive and few got extinct
How does the Black Rhinoceros develop?
By natural selection. (Some natural obstacle prevent the other rhinceros to mix with the black.)
What level does natural selection occur at?
natural selection occurs when animals need it
Which is more likely to be true natural selection or evolution?
Evolution, of course. Evolution can happen without natural selection in some cases; drift, flow. Generally though, natural selection causes evolution and then, by definition, would come first.
What are some objections to natural selection?
Natural selection does not respect the rights of the individual. If you care for the rights of the individual - your own, for instance - you should avoid being naturally selected against. Fortunately, humans have expanded their control over their environment to such a degree that natural selection no longer has the role in our development that it has for 'wild' life forms. This makes it somewhat easier for us to consider the phenomenon of natural selection from an objective stance.
Explain how natural selection is at work when a species becomes extinct?
According to science, natural selection chooses the best features for the best survival. When those processes do not occur for some reason, the species does not survive.
Which force of evolution makes a population more alike?
Stabilizing selection occurs when the extreme forms of some trait are selected against by natural selection. It is a force of natural selection which causes evolution (definition: change of allele frequency in a population divided by time).
When lions prey on a herd of antelope some antelope are killed and some escape which part of Darwins concept of natural selection might be used to describe this situation?
Survival of the fittest would be used to describe this situation.
What is the relationship between Natural selection and Genetics?
Natural selection ' selects ' from among variations. Some organisms are better suited to their immediate environment and survive and out reproduce other organisms. All these organisms are genetically variant. That is the simple connection between natural selection and genetic variation. ( that variation coming about by mutation and recombination )
