Molecular and cellular function and grouping refer to which of the following characteristics of life?

Russian scientists have discovered fossil evidence of a group of “dwarf” mammoths on an island in Siberia. Carbon dating indicates that these mammoths were alive 6,000 years after other mammoth species became extinct.

• Some scientists think these “dwarf” mammoths survived because the island was isolated from humans.

• Other scientists think the milder climate on the island allowed them to survive longer.
