Your friend remarks, "The giraffe stretched its neck while reaching for higher leaves; as a result, its offspring inherited longer necks” Which statement is the best response to correct your friend’s misconception?
Overproduction of offspring leads to a struggle for survival.
Only favorable adaptations have survival value.
Characteristics acquired during an organism's life are generally not passed on through genes to its offspring.
Disuse of an organ may lead to its eventual disappearance.
The more closely related two different organisms are, the
more similar their habitats are
less similar their DNA sequences are
more recently they shared a common ancestor
less likely they are to have the same genes in common
According to natural selection theory,
Adaptations beneficial in one habitat should generally be beneficial in all other habitats
Different species occupying the same habitat will adapt to that habitat by undergoing the same genetic changes
Adaptations beneficial at one time should generally be beneficial during all other times
Well-adapted individuals leave more offspring, and thus contribute more to the next generation's gene pool, than do poorly adapted individuals
For some traits (such as birth weight in mammals), natural selection favors individuals that are average and the extremes are selected against. This is known as
directional selection
