Describe natural selection.
A. Individuals that are better adapted tend to survive and produce more offspring, while less well adapted individuals tend to die or produce fewer offspring so each generation contains more offspring of better adapted organisms.
B. Individuals that are better adapted tend to die and produce less offspring, while less well adapted individuals tend to survive and produce more offspring so each generation contains more offspring of less adapted organisms.
C. Individuals that are better adapted tend to survive and produce new species, while less well adapted individuals tend to die or produce fewer new species so each generation contains a larger variety of species
D. None of the above
A. Individuals that are better adapted tend to survive and produce more offspring, while less well adapted individuals tend to die or produce fewer offspring so each generation contains more offspring of better adapted organisms.
