The human hemoglobin molecule contains a chain of 146 amino acids. The chart below shows how many amino acids in other animal hemoglobin differ from the human hemoglobin. Based on this evidence alone, to what animal are humans more closely related?

• Rhesus monkey

• Mouse

• Chicken

• Frog

Chicks and humans both have gill slits during development. What does this tell us about chicks and humans?

• Their embryos use gills to breathe during development.

• They both evolved from a common ancestor who had gills.

• Chicks are able to breathe underwater.

• They evolved from different ancestors.

Which statement can be best supported by the pictures of the embryos.

• Chickens are more closely related to tortoises than rabbits are.

• Rabbits, chickens, tortoises, and fish are all equally related to each another.

• Fish do NOT share a common ancestor with other vertebrates.

• Fish and chicken are the least closely related.

A ___________ is the trace, or remains, of an organism, usually found in sedimentary rock.

• fossil

• index fossil

• dinosaur

Scientists can determine relatedness among organisms by comparing partial amino acid sequences. The table shows four partial amino acid sequences from four organisms. Which organism is the least related to the other three organisms?

• organism 1
