What can scientists determine about the evolutionary relationship between species by comparing amino acid sequences for hemoglobin?

Back

It can provide evidence about the relatedness of the different species: if they are more similar they have a more recent common ancestor.

Front

When comparing amino acid sequences for hemoglobin in humans, horses, and gorillas, which two were most closely related? Options: horses and gorillas, horses and humans, humans and horses, humans and gorillas

Back

humans and gorillas

Front

List the 4 closest human relatives based on the biochemical comparison of Cytochrome C protein differences.

Back

chimpanzee, gorilla, rhesus monkey, horse

Front

List the 4 most distant relatives based on this biochemical comparison. Options: bread mold, snapping turtle, gorilla, fruit fly, bread mold, tuna fish, rhesus monkey, rattlesnake, bread mold, gorilla, horse, chimpanzee, bread mold, fruit fly, tuna fish, snapping turtle

Back

bread mold, fruit fly, tuna fish, snapping turtle

Front

Which of the following would NOT be considered a fossil? Imprints of claws in dried mud, teeth found on the jaw of an extinct dinosaur bone, a Wooly Mammoth preserved in ice, an x-ray of a fractured arm

Back

an x-ray of a fractured arm

Front

How do fossils provide evidence that evolution has happened on Earth?

Back

Fossils show how life forms present today are different than those from the past

Front

How does comparing homologous structures provide evidence of evolution?

Back

The genes for the body plan and forelimb layout were present in a common ancestral species vertebrates share, thus passed onto all vertebrates.

Front

A fossil of an extinct dinosaur is found and the anatomy of the fossil shows similarities to that of a bird. What could this mean?

Back

The extinct dinosaur and modern bird share a common ancestor

Front

The diagram above shows an embryo of different vertebrates at different stages of development. Which field of study would support the similarities in development as evidence for evolution? Options: comparative biochemistry, paleontology, comparative biogeography, comparative anatomy

Back

comparative anatomy

Front

What can we deduce from the evidence of animals with similar characteristics living in similar environmental conditions on different continents? (e.g., Anteater/Armadillos of the Americas and Pangolin of Africa)

Back

Living things can adapt similarly to similar environments over time.
