Evolution

Change in genetic composition of population of organisms; like antibiotic resistance by bacteria

Natural selection

How evolution works using selection pressures (forces that promote success of others) and adaptations (features that enable organism to succeed)

Chimpanzee

The closest relative to humans, ~98.4% same DNA

Evolutionary relationships

Helps us choose animals for biomedical research; rats are used more than chimpanzees

Primates

Order of mammals to which humans, monkeys, and apes belong

Bipedalism

Standing and walking on two legs to help spot predators and carry food, tools, and infants
