BS Bio Review 5 - Darwin

The species of finches that Darwin found on the Galapagos Islands displayed different adaptations. One of the adaptations that Darwin notes was the

• similarities of the birds' embryos

• birds's different-shaped beaks

• length of birds necks

Based on the adaptations Darwin observed in finches and tortoises in the Galapagos, he wondered

• if species living on different islands had once been members of the same species

• if finches and tortoises had originated form the same ancestral species

• if all birds on the different islands were finches

Hutton's and Lyell's work was important to Darwin because these scientists

• explained volcanoes and earthquakes

• explained geologic events on Earth

• suggested that Earth was old enough for evolution to have occurred

Darwin realized that the economist Malthus's theory of population control

• applied only to humans

• could be generalized to any population of organisms

• could be generalized only when populations lived in crowded conditions

Darwin's observation that finches of different species on the Galapagos have many similar physical characteristics supports the hypothesis that these finches

• descend from a common ancestor

• acquired traits through use and disuse

• all eat the same type of food

When lions prey on a herd of antelopes, some antelopes are killed and some escape. Which part of Darwin's concept of natural selection might be used to describe this situation?

• acquired characteristics

• reproductive isolation

• survival of the fittest

Darwin called the ability of an organism to survive and reproduce in its specific environment

• diversity

• fitness

• common descent

Darwin's concept of evolution was NOT influenced by

• his trip on the H.M.S. Beable

• knowledge about the structure of DNA

• his collection of specimens

The hypothesis that species changed over time by natural selection was proposed by

• James Hutton

• Jean-Baptiste Lamarck

• Charles Darwin

Darwin's theory of evolution suggests that

• species change over time

• extinct species are not related to living species

• different species can interbreed
