Evolution: The development of complex organisms from simple celled organisams by a process of natural selection over millions of years
Larmarck's Theory: If an animal used a body part, it would get bigger and the bigger organ would be passed on to its offspring
Darwin's Theory: All species of living things have evolved from simple life forms that first developed millions of years ago
Darwin's Observations:
- Living things produce offspring, many of which die before reaching adulthood
- There is variation between the same species
- Variation allows some individuals to survive better when conditions change
- Those with advantageous adaptations are more likely to survive and reproduce, passing on the characteristic. The better genes ( alleles) become more common
