Evidence for evolution, cladograms, natural selection

This type of evidence for evolution shows us, through remains of organisms, how life has changed.

• fossils

• homology

• embryology

• dna

This type of evidence for evolution suggests that organisms with similar structures are related.

• Fossils

• Homology

• Biogeography

• DNA

This type of evidence for evolution says that if an organism looks like another in the early stages of development then they are more related.

• Embryology

• Fossils

• DNA

• Homology

Recently, scientists have been able to use ___________to find common proteins and amino acids to determine how closely related species are.

• DNA

• Vestigial structures

• Fossils

• Homologous structures

Which of the following do scientists not use as evidence for evolution?

• Fossils

• Vestigial Structures

• Embryology

• Radiation

If two modern organisms are distantly related in an evolutionary sense, then one should expect that

• they live in very different habitats.

• their chromosomes should be very similar.

• they shared a common ancestor relatively recently.

• they should share fewer homologous structures than two more closely related organisms.

What are the evidences for Evolution?

• Fossil Records
• Embryology
• Similar body structure
• All the above

This type of evidence for evolution explains why organisms around the world that are not directly related may have the same features and traits.

• homology

• dna

• biogeography

• vestigial structures

The ability of an organism to survive in an environment and then successfully reproduce makes that organism more _______ for its environment.

• strong

• better

• fit

• tall

In a population of lizards the ones with longer tails seem to survive because birds think the tails are snakes.  Small tail lizards are almost nonexistent and there are only a few of the medium tail lizards. 

What type of natural selection is this?

• stabilizing

• directional

• disruptive
