Some behaviors, such as nest building in birds, are determined by the genes of an organism. These innate behaviors are inherited from parent to offspring and exhibited even if the offspring does not observe its parent performing the behavior. Nest building behavior was most likely an evolutionary advantage because birds that built nests were more likely to raise their young to maturity and thus increase their reproductive success. That is, birds that laid their eggs in nests had more offspring survive to adulthood than those that did not.
Behaviors that are determined by genes and that give an organism increased reproductive success usually become common in a species due to
A.
natural selection.
B.
asexual reproduction.
C.
random chance.
D.
autosomal mutation.
