EOC Review - Evolution

Front

What conclusion can be drawn about vertebrates based on the fossil record?

Back

Vertebrates appeared in the oceans before they moved on to land.

Front

What indicates that speciation has occurred in related organisms?

Back

Two groups cannot interbreed successfully.

Front

What defines a species in biological terms?

Back

Animals are classified as the same species when they can interbreed to produce fertile offspring.

Front

What is sympatric speciation?

Back

Sympatric speciation occurs when new species arise from a single ancestral species while inhabiting the same geographic region.

Front

What role does sexual selection play in speciation?

Back

Sexual selection can lead to speciation when females prefer males with certain traits, leading to reproductive isolation.

Front

What are antibiotics effective against?

Back

Antibiotics are most effective in killing bacteria.

Front

What is the significance of the fossil record in understanding evolution?

Back

The fossil record provides evidence of the historical sequence of life and the evolution of species over time.

Front

What is the difference between allopatric and sympatric speciation?

Back

Allopatric speciation occurs when populations are geographically isolated, while sympatric speciation occurs without geographic isolation.

Front

What is a common example of natural selection?

Back

The peppered moth's color change during the Industrial Revolution is a classic example of natural selection.

Front

What is the role of mutations in evolution?

Back

Mutations introduce genetic variation, which is essential for natural selection to occur.
