- In the 18th century people began to accept
that two organisms evolve into one.
- In 1859 Darwin Published a book
- Genetic Variation
- Characteristics of individuals vary due to differences in genes
- Environmental change
- Conditions
in an area
change, lack
of resources
(food)
causes more
competition
between
organisms.
- Natural Selection
- By chance, the variation of some
individuals make them better at
coping than others
- 'Survival of the fittest'
- Inheritance
- Survivors breed and pass on their variations, to their
offspring, so the next generation contains more individuals
with better adapted variations
- Evolution
- If enviornmental conditions
remain changed, natural
selection occurs over and
over again, and a new specie
evolves with all the
individuals having the better
adapted variations
- Darwin (1809-1832)
