Evolutionary Theory

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.
