• an adaptation

• an organisms fitness

• a mutation

• artificial selection

Which of the following is the most recent science in terms of supporting Darwin's work on his Theory of Evolution from the 1800's?

• New fossils being discovered every day

• Biogeography supporting how fossils are different and NOT related

• Molecular biology supporting a common ancestor

• Molecular biology supporting several ancestors

According to the phylogenetic tree shown, of the following, who is the most closely related to turtles?

• Amphibians

• Cartilaginous fish

• Jawless fish

What made Darwin unique when comparing his observations to other scientists of his time when specifically defending his Theory of Evolution?

• He explained the mechanism for how evolution happened

• He listed his observations in a notebook

• He used a logical explanation for all of his observations

• He used molecular biology to support his claims

What was the driving force in nature that explains Darwin's finches developing different phenotypes?

• Food availability

• Predator selection

• Artificial selection

• A common ancestor

According to Darwin, which of the following best explains why the mara is more similar to other South American mammals than to the North American rabbit?

• It shares a closer ancestor with the South American animals.

• It shares amino-acid sequences with other South American animals.

• Its genotype is similar to South American animals.

• Its geographic distribution indicated little change over time.

Which of the following is a correct statement about the relationship between natural selection and evolution?

• Natural selection includes evolution as a part of it.

• Natural selection is one of many mechanisms of evolution

• Natural selection results from evolution.

• Natural selection and evolution as the same thing.

What type of adaptation is shown in the picture?

• artificial selection

• mimicry

• camouflage

• homologous structure

Superficially similar features molded by natural selection in very different species are classified as what kind of structures?

• comparative

• homologous

• vestigial

• analogous

How do fossils demonstrate evidence of evolution?

• fossils reveal that many species have remained unchanged for millions of years

• they show that ancient species share similarities with species now on earth.

• they are the primary source of evidence for natural selection.

• They show evidence of species now extinct.
