What is the necessary conditions for evolution to occur?
Variation must exist.
What conditions would be necessary for evolution of resistance to the toxic protein to occur in the corn borer?
the factors that are necessary for natural selection by evolution to occur are: 1)variation in characteristics;different individuals in a population must have different characteristics. 2)differencies in fitness different characteristics of different individuals must contribute to differences and fitness. 3)heritability of characteristics characteristics that affects fitness must be heritable.... example:passed by genes from one generation to the next)
How is variation within a species allowing different phenotypes to be selected important for evolution to occur?
Convergent Evolution-Evolution toward similar characteristics in unrelated species, resulting from adaptions to similar environmental conditions. Divergent Evolution- Evolution of one one or more closely related species into different species, resulting from adaptions to different environmental conditions.
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.
