How did Darwin in the 1800s explain the origin of species?
Species originate through adaptation by natural selection. Strange thing really, Darwin didn't even believe in evolution.
Is natural selection same as survival of the fittest?
According to evolutionary theory, natural selection is the principle that directs evolution.
Can natural selection occur in an individual organism?
No, its a group thing.
Besides Darwin the theory of evolution by means of natural selection was also independently proposed by who?
Alfred Russel Wallace.Wallace was a naturalist who independently came up with the idea of natural selection while traveling in what is now Malaysia and Indonesia. He sent a letter outlining his ideas to Charles Darwin, to whom it came as a great shock.Darwin had been working on his theory of natural selection for at least 20 years and did not know what to do. His friends Charles Lyell and Joseph Hooker decided that the fairest thing to do was to present Wallace's essay and Darwin's own writings jointly to the Linnean Society in 1858.Meanwhile Darwin rushed to complete a shorter version of his intended book, which was published in 1859 as 'On the origin of species'.You can see the letters at www.linnean.org/index.php?id=380
What made the Galapagos Islands special to Charles Darwin for evolutionary study?
The key thing that Darwin realised soon after arriving at the Galapagos was that the islands had been formed relatively recently. Because of this, a relatively small number of species had arrived at the islands and variations on these species had arisen on the different islands. This made Darwin ask how the variations had occurred; leading, eventually, to the theory of Natural Selection.
How do natural selection cloning and selective breeding lead to evolutionary change?
The only thing that causes evolution is Mutations due to forced natural selection of desired alleles.
How does population change as a result of natural selection?
Natural selection is not a thing that acts on populations, it is a tendency for harmful genes to not be passed on (die out) and useful variations to thrive and become common.
Natural selection allows a species to change in response to its environment. What is the process by which a species becomes better suited to its environment called?
Adaptation (I'm studying the same thing ;)
How does non sexual natural selection affect the appearance of male guppie?
Because their population grows and their thing grows ;)
Was evolution around before natural selection?
These two things are both theories that are pretty much the same thing.
Did Charles Darwin admit that evolution didn't occur?
No. There was a rumor circulating that Darwin recanted evolution on his death bed, but that rumor has no foundation or plausible evidence. And even if Darwin ever had said such a thing, it would be meaningless. Galileo recanted is heliocentric theory, under pressure from a religious group. That in no way alters the fact the earth orbits the sun, and not the other way around.
What is the only thing that natural selection can act on?
The phenotype or genome of the individual organism. Remember, individuals are selected, populations evolve.
