Evolution would not occur if there is no genetic variation within a population, no selection pressure, or if there is no reproduction and passing on of genes to the next generation.
Evolution can occur at different rates depending on various factors such as the generation time of the organism, environmental pressures, and genetic variability. In some cases, evolution can be slow, taking thousands to millions of years for noticeable changes to occur. In other cases, evolution can happen relatively quickly, especially when organisms face changes in their environment that require rapid adaptation.
For a scientist to argue that evolution does not exist based on DNA evidence, her findings would need to demonstrate that genetic mutations do not occur, that species do not share common ancestry, and that there is no evidence of natural selection influencing genetic variation over time. This would contradict the vast body of scientific evidence supporting the theory of evolution.
Without heredity what use would there be to selection and why evolution? Just take beneficial mutations in the germ line for example. No heredity and nothing to enter the populations gene pool and no evolution. No heredity and there would be no variation in populations and the first environmental challenge would carry your population to extinction.
An important mechanism in evolution is natural selection, which allows populations to develop adaptations to changing circumstances based on the fitness landscape of the environment. Nah, still doesn't work. I'm no good at long sentences.
Some would call that microevolution. I would not. Some divide evolution into micro and macro. Evolutionary biologists prefer to use the terms evolution and speciation.
Under what circumstances would it be advisable to borrow money to take a cash discount?
under normal circumstances, she would be your grandmother
Under no circumstances
Evolution cannot occur.
Circumstances are things that are set in place or situations that occur. An antonym would be Volition.
Under the right circumstances, yes.
hi, i am Tran
It would depend on who you are slapping, and under the circumstances of the situation.
Without knowing which Alexander or under what circumstances you are referring to it is not possible to give a definitive answer.It is quite likely he had the same feelings as anyone else would under the circumstances.
If you answer "Other" to the question, "What is your citizenship?"
under circumstances, yes
Under different circumstances maybe.
