Question

Although most naturalists acknowledged that "things change," Darwin and Wallace gained support for their proposed hypothesis because

a. they proposed that organisms remained static for a long period of time, and then underwent rapid changes to adjust to a new environment.

b. they proposed that organisms modified themselves during their lifetimes, and passed on traits to offspring.

a. they proposed that organisms remained static for a long period of time, and then underwent rapid changes to adjust to a new environment.

Explanation / Answer

c) They proposed that the organisms that survived were better adapted to the environment, and favorable variations were able to be passed on to future generations. This is called Survival of the fittest.

For example; In an ecosystem, some giraffes have long necks and others have short ones. If something caused low-lying shrubs to die out, the giraffes with short necks would not get enough food. After a few generations, all the giraffes would have long necks.
