Do Human and Chimpanzee DNA Indicate an Evolutionary
Relationship?
n Human
DNA is 98% similar to chimpanzee DNA.
n Watson
and Crick opened - the genetic makeup of humans and animals.
n Compare
the proteins and nucleic acids of one species with those of another.
n Structural
differences
n in
the skeleton,
n the
muscles,
n the
skin,
n and
the brain;
n differences
in posture associated with a unique method of locomotion;
n differences
in social organization; and
n finally
the acquisition of speech and tool-using, together with the dramatic increase
in intellectual ability.
n Scientists
to name their own species Homo sapiens sapiens – wise wise men.
