A Stress on a Biological Organism, over time and, an overall balancing this stress, that isn't normally taken care of, by regular day to day, equalizations.
yes.
Organisms are required for evolution to occur. Evolution is defined as something that happens when organisms reproduce.
For a mutation to affect evolution it must occur in the dominant allele. This allele is what is passed on.
The only known instance of evolution occurring is here, on Earth. Logic dictates, however, that evolution occurs wherever there is life.
Biological evolution is the process of changes that occur in living beings that can be passed on to their offspring. Chemical evolution is the process of changes that occur in substances. However, scientists have found that these substances have changed to form organic molecules, meaning that they have created life from nonliving substances.
how variations occur within a species
The key component of evolution is reproduction of the species.
yes.
Because adaptations are an observed effect of evolution. They could not happen if evolution did not occur.
Organisms are required for evolution to occur. Evolution is defined as something that happens when organisms reproduce.
Descent with modification encapsulates the two key ideas central to the theory of evolution. These are that modifications (mutations) occur, and that these mutations are inheritable (passed on to descendants or offspring).
Evolution occurs in population not in an individual.
Yes. Evolution ocurred in all geologic periods.
You do not allow evolution to occur, for you are evolution in selective breeding.
The more variation there is in a group of specimens, the more evolution can occur between them.
Down Syndrome is a the addition of an extra chromosome and not really related to evolution. It is more of a genetic mutation that causes this event to occur.
For a mutation to affect evolution it must occur in the dominant allele. This allele is what is passed on.
