Question

what conclusion can you draw from this data?
a. rattlesnakes evolved from bakers yeast.
b. bakers yeast and cauliflower are the same species.
c. humans are more closely related to chimpanzees than garden snails.
d. cauliflower evolved from garden snails.

Explanation:

Evolutionary relationships are often indicated by genetic or molecular similarities. Here, the percentage difference values likely represent genetic or molecular differences (though the exact molecule isn't specified). A smaller percentage difference implies a closer evolutionary relationship.

• Option A: Rattlesnakes and baker’s yeast are very different organisms (one is an animal, the other a fungus). There is no data suggesting a direct evolutionary lineage from baker’s yeast to rattlesnakes.
• Option B: Baker’s yeast (a fungus) and cauliflower (a plant) are different kingdoms of life. They cannot be the same species.
• Option C: Chimpanzees are primates (like humans), and garden snails are mollusks. The percentage difference (assuming it's for a relevant molecule like a protein or DNA) for chimpanzees (0% difference compared to humans) is much smaller than for garden snails (10% difference), indicating a closer evolutionary relationship between humans and chimpanzees.
• Option D: Cauliflower (a plant) and garden snails (mollusks) are different kingdoms. There is no data to support an evolutionary lineage from garden snails to cauliflower.

Answer:

C. Humans are more closely related to chimpanzees than garden snails.
