Process by which organisms acquire and pass on novel traits through generations?
evolution or natural selection
What is the most important force in shaping evolution?
Evolution has two key driving forces without which it would not occur, but with which it must occur: The first is reproductive variation: this basically asserts that each organism is slightly different from both its parents and its siblings. The second is differential reproductive success: this asserts that features that allow their bearers to reproduce more successfully than members of the same species with different features are likely to be present in a greater part of the population in coming generations. In other words: the key driving forces behind evolution are variation and selection.
Who founded the modern theory of evolution?
There are several different theories of evolution. The most successful is by Charles Darwin through natural selection.
How can Darwinain evolution be true if more than 99 percent of genetic mutations are retrogressive?
Darwinian evolution works very slowly over hundreds of generations. Though 99percent of mutations may be lost through natural selection the remaining 1 percent positive mutations will eventually, given sufficient time, improve the fit of the species to it's environment.
What are the mechanism evolution called?
Natural selection. The process of minor mutations causing an individual with a slightly better chance of survival to be the one whose genetic material influences future generations.
Which concept is part of the theory of evolution by natural selection?
New generations are better suited to survive than previous generations.
Process by which organisms acquire and pass on novel traits through generations?
evolution or natural selection
The hypothesis that the evolution of different species occurs?
natural selection
Is natural selection same as survival of the fittest?
According to evolutionary theory, natural selection is the principle that directs evolution.
How does sexual reproduction speed up the evolutionary process?
Evolution can only be seen through generations. Natural selection allows those that have the advantageous genes to live, and others to die out. Therefore, it takes many generations to see the effects of evolution on a species. Increasing sexual reproduction allows the turnover of generations to be quicker. Since we can only see the changes in future generations of a species, more reproduction will let those generations get here quicker, and therefore evolution can occur faster.
Why did Darwin state that you could never watch natural selection in action?
The smallest unit that can evolve is the population, not the individual. In other words, you can't evolve, but over generations, the population can be subject to natural selection and different traits can be selected. In addition, the evolution of a population will take generations of fluctuating gene frequencies, something you can't just watch in action. Of course, the speed of evolution is entirely dependent on the environment; some populations will evolve quicker than others.

Is natural selection a cause of evolution?
No, natural selection is believed to result in evolution.

How is natural selection and evolution linked?
Natural selection is one of the 'guiding' principles of evolution.
Can natural selection exist with out evolution?
Perhaps not, but evolution can exist without natural selection.
