What is basis for evolution by natural selection?
The basis for all science, be it evolution or the study of how squeaky noises annoy people, is evidence. Darwin's primary evidence for evolution by natural selection was morphological homology; physical similarities between species. Modern evidence for evolution by natural selection is vast and includes a rich fossil record, well understood geologic evidence, radioisotopic evidence, as well as a host of genetic evidence from protein homologies to complex molecular systematics. All evidence for evolution converges on the singular observation that all organisms can be organized in a nested hierarchy much like a family tree; a Tree of Life.
Why evolution of man considered as a complex process?
The evolution of man is considered a complex process because it takes thousands of years for even a small change to occur. It is a result of genetics and physiological changes which take many generations to take hold.
Why evolution should not be equated with progress?
Evolution is simply the generation of diversity and the shaping of the diversity by environmental selection. Species adapt to the conditions available in their environment. Some older and simple species live on quite effectively. The only progressive trend in evolution seems to be that more and more complex body designs have emerged over time. In fact, one of the simplest life forms like bacteria - inhabit the most inhospitable habitats like hot springs, deep-sea thermal vents and the ice in Antarctica. This is the reason why evolution in not equated with progress.
What is inorganic evolution?
Inorganic evolution is the theory of the creation of the universe, not of the species of animals found on earth (ie organic evolution). It does seem to be a point of contention among a few as how this led to complex compounds. There is no connection as no scientific evidence has shown it, yet.
Photosysnthesis is a very complex process which suggests design?
To those who are looking for evidence of intelligent design, all the complex processes of life suggest design. However, they are explicable by evolution. Life has been evolving on the planet Earth for billions of years, which is long enough for complex processes to evolve.
Complex behavioral patterns such as altruism can evolve in a species as the result of natural selection?
Yes. Evolution, especially of the higher functions of the brain, leads to complex behaviour.
What is the correct order of stages which must have occurred in evolutionary history for complex cells to have evolved?
The emergence of the first cell is believed to have occurred 3.8 billion years ago. Atmospheric conditions and the appearance of the macromolecules may have started cell evolution.
What is a Evolutionary Trends?
Evolutionary trends are either progressive or retrogressive. During progressive evolution new structures are created whereas in retrogressive evolution the existing structures are reduced or eliminated.

What is the theory of evolution that complex chemicals are necessary for life that could evolve naturally from simpler molecules known as?
Is it the elemental evolution, a chemical evolution, a nuclear evolution or a molecular evolution? Please choose one of the following.
How is cultural evolution similar to natural selection?
Cultural evolution is the phenomenon whereby cultural ideas, notions, views, etc. propagate throughout populations, like alleles propagate throughout population gene pools in biological evolution.Some propose that the way these ideas propagate throughout populations is similar to the ways of biological evolution, in that cultural ideas (or memes) are subject to a kind of cultural selection, that determines how fast they spread, and to what degree.
Is Genetic diversity is the raw material for evolution?
Mutations occur randomly, and every once in a blue moon, a mutation offers some benefit to a individual of a particular species in a particular place and allows that individual to have more offspring than its peers. If the mutation provides enough benefit to some individuals, they will have a tendency to survive and reproduce (as per the principle of natural selection). Natural selection reduces variability by killing off less fit individuals. It is mutations that increase the variability and allow evolution (successful natural selection, not mass extinction, but controlled deaths) to occur. Without variability there is no evolution.
How has evolution helped life to continue?
Actually, it's life that has helped evolution to continue - or perhaps one might regard life and evolution as parts of the same complex thing. It's certainly impossible to consider one without the other.Evolution has helped life to adapt to changing circumstances, such as shifts in climates, or drifts in geology and geography, through natural selection - the weeding out of less reproductively fit variants.
What are some of Darwin's ideas about evolution?
Darwin's main idea relating to Evolution is that complex beings evolve from simplistic beings naturally over time, beneficial traits are preserved to aid survival and passed onto the next generation. Natural selection: One key part of Darwin's theory of Evolution is natural selection, which is the preservation of a functional advantage that enables a species to compete better in the wild. Natural selection eliminates inferior species gradually over time. Sexual selection: This relates to the attraction a being has to others of the same species. The species uses a particular trait to attract others of the same species and give it a better chance of passing on it's genes. An example of this being the peacock and it's tail.
Define the evolution of quality control?
In the simplest sense, evolution means the slow process of change from a simple, to a more complex structure.
Define cultural evolution?
Cultural evolution is the change of culture from simple to complex form and also from homogeneous qualities t hetrogeneous
