question 2 (1 point)
above is the image of the fossil of a dorudon, an aquatic mammal that lived over 40 million years ago. the dorudon was a whale - like animal that had small, underdeveloped hind limbs.
which of the following best explains how fossils like the dorudon can support the theory that life on earth has evolved over time?

a they demonstrate that animals that dont evolve will die out

b they suggest that animals evolve from previous species.

c they confirm that some animals will not evolve

d they show that only animals evolve from previous species.

Explanation:

• Option a: The fossil of Dorudon doesn't show that non - evolving animals die out. It's about the evolution of species, not the fate of non - evolving ones.
• Option b: Dorudon is a whale - like animal with underdeveloped hind limbs. This suggests a link to previous species (like land - dwelling ancestors), supporting the idea that animals evolve from previous species.
• Option c: The fossil shows evidence of evolution (the hind limbs' development), so it doesn't confirm that some animals don't evolve.
• Option d: The fossil only gives evidence for animal evolution from previous species, but it doesn't mean only animals evolve from previous species (plants etc. also evolve). So this is an over - generalization.

Answer:

b. They suggest that animals evolve from previous species.
