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.

Lamarck’s ideas about evolution include the concept that differences among the traits of organisms arise as a result of

• continual increases in population size.
• the actions of organisms as they use or fail to use body structures.
• an unchanging local environment.
• the natural variations already present within the population of organisms.

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.

• applied only to humans.
•  could be generalized to any population of organisms.
• could be generalized only when populations lived in crowded conditions.
• explained why the number of deaths exceeded that of births.
