Applied Bio 16.1 & 16.2

Multiple Choice

The process of change over time is

• fossilization

• biodiversity

• evolution

• geology

Multiple Choice

Darwin's ideas are relevant today because

• they help us understand how disease organisms change over time

• they give us clues to Earth's biological past

• they help us understand relationships between living things & the natural world

• all of these

Multiple Choice

During his voyage on the HMS Beagle, Darwin noticed that similar habitats in different parts of the world contained

• the same plants & animals

• different but ecologically similar plants & animals

• ecologically different plants & animals

• the same fossils

Multiple Choice

Darwin noticed that within a local area, different but closely related species

• lived in different habitats

• lived in the same habitat

• competed for food

• competed for mates

Multiple Choice

Darwin drew support for his theory of evolution from the observation that fossils

• belong to ancient species that are now extinct

• of dinosaurs prove that dinosaurs once existed on Earth

• share a common ancestor

• of some extinct animals are similar to living species

Multiple Choice

Hutton and Lyell's research suggested that Earth

• is only a few thousand years old

• changes slowly over long periods o ftime

• now has geological processes that are different than from those in the past

• has not changed much over time

Multiple Choice

Darwin's observations of fossils of marine animals found several thousands of feet above sea level can be explained by

• ancient people moving the fossils to higher ground

• marine animals adapting to live far from the sea

• geological events causing the ancient seafloor to move to a higher elevation

• Darwin's misidentification of fossils

Multiple Choice

Lamarck proposed that species change due to

• competition for food

• use or disuse of organs

• differences in survival

• genetic mutations

Multiple Choice

Darwin realized that Malthus' ideas about human population growth applied even more to other organisms, such as how

• oysters produce millions of eggs but only a few survive

• mammals carefully raise one or two young per year

• elephants are overpopulating the earth

• insect populationsgrow unchecked each year

Multiple Choice

Selective breeding by humans to enhance the useful traits of domesticated organisms is known as

• natural selection

• artificial selection

• evolution

• Lamarck's hupothesis
