• Brighter colored fur
• Shorter claws
• larger/stronger teeth

In a hospital people use hand sanitizer and antibiotics all the time. How are they accidentally causing bacteria to go through natural selection?

• Nothing will happen
• Only the weak bacteria survive so they become easier to kill with antibiotics
• Only the smart bacteria survive, so the bacteria will become more intelligent
• Only the strong bacteria survive so the next generation of bacteria are more likely to resist antibiotics

Jean-Baptiste Lamarck proposed that organisms 

• have an innate tendency toward complexity and perfection.
• have an innate tendency to become simpler as time passes.
• inherit all of the adaptations they display.
• belong to species that never change.

The economist Thomas Malthus suggested that

• in the human population, people die faster than babies are born.
• without certain checks on population size, there would soon be insufficient food for the growing human population.
• in the 1700s, England needed more housing.
• the majority of a species’ offspring die.
