with the theory of natural selection, darwin proved that it is all down to "the survival of the fittest" meaning, that the strongest of a species will always be the last to die off, therefore it has more chance of reproducing and handing its genes down.

What is the word for the definition genetic change in population over time?
Long time = evolution. Short time = mutation.
What events may have lead to genetic changes over time?
Mutation can lead to genetic changes over time!
What is meaning of background mutation?
A background mutation is a slow evolving mutation that is not immediately recognizable. The mutation is carried on over generations in reaction to an environmental change.
What will an over population problem lead to?
Over population will usually lead to a lack of employment opportunities.
When does a mutation have the most impact on allele frequency?
There is no gene flow - APEX
Does somatic mutation contribute to evolution?
No. Only germ line mutation can be passed on. Somatic mutations die with the organism that processes them. The change in allele frequency over time in a population of organisms, evolution, can not take place if the alleles can not get onto the population through the organism having progeny; the result of germ lines.
What do sexual reproduction mutation and crossing-over generate in a population?
genetic diversity!:) ur welcome
What process thought to have changed the genetic code over billion years ago?
Basically, random mutation and natural selection. With a little genetic drift and gene flow thrown into the mix. Evolution, the change in allele frequency over time in a population of organisms.
What is micro-evolution?
Microevolution is the change in allele frequencies brought about by mutation, genetic drift, gene flow, and natural selection below the species level. Over time, microevolution can translate into macroevolution, which is larger scale change above the species level.Microevolution is simply a change in gene frequency within a population. Evolution at this scale can be observed over short periods of time.
A random change in a population's allele frequency?
Evolution is the change in allele frequency over time in a population of organisms. By mutation, genetic drift, gene flow and natural selection.
How does mutation lead to evolution?
its called survival of the fittest. if by some chance there is a mutation during a time of change in a living things surroundings and the mutation helps that living thing survive while other living things not "fit" to survive that change will have a lesser chance of surving. If that mutation passes on to the mutated living things children then that is what leads to evolution in living things.
Can evolution explained by science?
Evolution, the change in allele frequency over time in a population of organisms, is explained by science. Natural selection, mutation, genetic drift and gene flow explain just about all of the basics of evolution.
