Evidence of Evolution Exam

Front

Which statement about the ancestry of the lizards from the genus Gallotia is best supported by this information?

Back

The common ancestor of the lizards first colonized the island of El Hierro.

Front

When looking at the fossil record above, what conclusion can be made based on the evidence? Options: None of the organisms are related, Tulerpeton is related to living tetrapods, but not to Tiktaalik, All of the organisms have a common fish ancestor, Ichthyostega are more closely related to living tetrapods than to Tulerpeton.

Back

All of the organisms have a common fish ancestor.

Front

Based on your understanding of anatomical homologies, which organisms most likely have a recent common ancestor? Options: 1 and 2 are homologous structures, 1 and 3 are homologous structures, 1 and 3 are analogous structures, 2 and 3 are analogous structures.

Back

1 and 3 are homologous structures

Front

How can evolutionary relationships among organisms be determined by comparing embryonic development?

Back

Embryos of more closely related organisms show greater similarities in development.

Front

Factors to compare to determine how closely species are related: Number of genes, Sequence of amino acids, Location of chromosomes, Physical similarities in body structure.

Back

Sequence of amino acids

Front

Which statement is best supported by the information in this dendrogram (cladogram)?

Back

Lesser pandas are more genetically similar to raccoons than they are to giant pandas.

Front

Which conclusion about the relatedness of the lizards do these data support? Options: G. atlantica and G. stehlini are the least closely related, G. simonyi and G. bravoana are the most closely related, G. galloti eisentrauti and G. galloti palmae are the most closely related, G. galloti eisentrauti and G. galloti galloti are the least closely related.

Back

G. simonyi and G. bravoana are the most closely related.

Front

Both these mammals incubate their immature offspring in a pouch. What does this provide evidence for?

Back

are descended from a common ancestor

Front

What best explains the existence of mammals, lizards, and birds on the islands of Maldives?

Back

The ancestry of the animals can be traced back to the nearby continent.

Front

The diagram above shows a model of species divergence among some primates. If this model is correct, the greatest genetic differences would be found in the DNA sequences of which two species? Options: Tarsius bancanus and Cebus albifrons, Macaca sylvanus and Macaca mulatta, Hylobates lar and Pongo pygmaeus, Pan troglodytes and Lemur catta

Back
