CP UNIT 7 REVIEW

The species of finches that Charles Darwin found on the Galapagos Islands displayed different structural adaptations. One of the adaptations that Darwin noticed was the

• Similarities of the birds’ embryos

• Birds’ different shaped beaks

• Length of the birds’ necks

• Number of eggs in each bird’s nest

Which of the following is NOT an evidence for evolution proposed by Charles Darwin

The similarity among the blood proteins (amino acid sequences)  of all mammals may be taken as evidence for evolutionary relationships based upon

• comparative anatomy

• comparative geographic distribution

• comparative embryology

• comparative biochemistry

According to Charles Darwin’s theory of natural selection, the individuals that tend to survive are those that have

• Characteristics their parents acquired by use and disuse

• Characteristics that plant and animal breeders value

• The greatest number of offspring

• Variations best suited to the environment

Charles Darwin’s theory of evolution suggests that

• Species change over time

• Extinct species are not related to living species

• Different species can interbreed

• Animals that look alike are the most closely related

The table shows the amino acid present at ten positions in the myoglobin protein in five different organisms. Based on this evidence, a researcher could conclude that

• The zebra and Gorilla are closely related.

• The closest relatives are the human and chimpanzee

• The closest relative is Horse and Zebra

• No amino acids at any position of the myoglobin protein remained unchanged across all animals.
