Evolution Test Review

The part of Lamarack's work that proved to be CORRECT was that

• evolution is linked to an organism's environmental conditions

• evolution relies on the use and disuse of physical featuresss

• changed traits are passed down to offspring

• changed traits develop slowly and gradually

The forelimbs of vertebrates

• serve the same function

• contain the same kinds of bones

• have different kinds of bones

• evolved from wings

There is clear evidence from fossils and other sources that the species now on Earth

• have evolved from ancestral species that are extinct

• have reached the ultimate in evolution

• will eventually evolve into the same species

• have always been the way they are now

Which of the following is a factor in natural selection?

• Individuals of a population overproduce

• All populations are genetically diverse

• Individuals better abel to adapt to changes leave more offspring

• All of the above

Darwin developed the theory of evolution by natural selection rom

• Malthus' ideas of population growth

• the observations he made during the voyage of the Beagle

• years of reflecting on his ideas

• All of the above

The fossil recored provides evidence that

• older species from the past gave rise to more recent species

• all species were formed during Earth's formation and have changed little since then

• the fossilized species have no connection to today's species

• fossils cannot be dated

Fossils have been found that provide a link in the evolution of whales from

• two-legged mammals

• legless amphibians

• four-legged mammals

• flightless birds

Species have changed over time, and their genes

• are less complex

• are not important in their evolution

• have changed as well

• All of the above

The fossil recored seems to provide evidence for

• intermediate forms

• extinction

• natural selection

• all of the above

The evolution of beak shapes in Galapagos finches is a response to

• the bodies of water present

• the types of food available

• whether the populations interbreed

• the nutritional content of seeds
