EOC Review Part 1

A bumble bee has just enough weight to open up the snapdragon flower and get the nectar/pollen inside.  Other insects cannot do this. This adaption is an example of........

• convergent evolution
• co-evolution
• divergent evolution
• speciation

Which of the following is required for a population to diverge into two separate species?

• The two populations must have evolved different physical appearances.

• The two populations must have mutated at least 10 times.

• The two populations must have become reproductively isolated.

• The two populations must have evolved analogous structures.

The palmarus longus tendon, pictured here, no longer serves a purpose in humans, but provides evidence of our species descendance from tree-dwelling ancestors. The palmarus longus tendon is an example of:

• a vestigial structure

• a homologous structure

• bipedalism

• convergent evolution

Which of the following means "genetic changes in a species over time"

• natural selection

• speciation

• evolution

• fitness

The emergence of new rivers or streams is a type of ____________ isolation.

• Temporal

• Mechanical

• Behavioral

• Geographic

Speciation that caused by breeding occurring at different time of the day is called

• behavioral isolation

• temporal isolation

• ecological isolation

• habitat isolation

The evolution of a new species from an existing species is ____.

• natural selection
• isolation
• speciation
• genetic variation

What type of speciation is this?

• Geographical

• Temporal

• Behavioral

What type of speciation is this?

• Geographical

• Temporal

Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called survival of the fittest.

• Extinction
• Speciation
• Natural Selection
