Study Notes
Evolution
- Evolution is the change in life on Earth over long periods, with living things adapting to environmental changes.
- Charles Darwin, known as the "Father of Evolution", proposed that all living things share a common ancestor and that species evolve over time.
- His theory is called "descent with modification".
- Species are groups of similar organisms that can reproduce and produce fertile offspring.
Darwin's Observations
- Darwin's ideas were based on global observations, from his travels on the HMS Beagle (1831-1836).
- Stops in South America, Australia, and Africa provided opportunities to study diverse life forms.
- Darwin observed finches on the Galapagos Islands, with distinct beak types suited to different food sources (e.g., nuts or insects).
Galapagos Finches
- Finch beak variations were observed across different islands, suggesting adaptation.
- Finches adapted to specific foods, leading to different beak shapes over time.
- Island isolation drove the development of new species, through gradual changes over generations.
Species Formation
- Darwin proposed that new species arose from pre-existing species, sharing a common ancestor.
- Heritable traits (genes) gradually accumulate differences as organisms adapt over many generations in response to their environment.
