Multiple Choice

The occurrence of the same blood protein in a group of species provides evidence that these species:

exhibit convergent evolution

have identical environmental adaptations

are members of the same genus

share a common ancestor

Verified step by step guidance

Understand that the presence of the same blood protein in different species suggests a genetic similarity, which is often due to inheritance from a common ancestor rather than independent development.

Recall that convergent evolution refers to unrelated species independently evolving similar traits, so the presence of the same protein is less likely due to this process.

Recognize that identical environmental adaptations might lead to similar traits, but the exact same blood protein implies a genetic link rather than just similar environmental pressures.

Note that being members of the same genus is a taxonomic classification and does not necessarily explain the presence of the same protein across species from different genera.

Conclude that the most scientifically supported explanation is that these species share a common ancestor, which passed down the gene coding for the blood protein.
