Adaptation and Heredity. Jean Baptiste Pierre Antoine de Monet, Chevalier de Lamarck (1744-1849) proposed new ideas about evolution. Lamarck believe that “use and disuse” would determine how species changed over time. Athletic training increases muscle size
But he did propose that species evolve over time in response to their environment, and changes are passed on over generations.
Charles Darwin began tracking observations in 1837, collecting data which he would use to create his theories on evolution.
Remote islands provided him a unique area to study, finding animals with unique behaviour and no fear of humans.
Divergent Evolution – two or more species become increasingly different due to environmental pressures.
Coevolution – the evolution of one species as a response to the evolution of another species.
