EVOLUTION
- Darwins theory
- Darwin's theory of evolution explains how life on Earth has changed over
geological time. Scientists believe this is the reason why all living things on
Earth exist today. The theory is supported by evidence from fossils, and by
the rapid changes that can be seen to occur in microorganisms such as
antibiotic-resistant bacteria. Many species have become extinct in the past
and the extinction of species continues to happen.
- Darwin’s theory conflicted with religious views
that God had made all the animals and plants on
Earth
- Darwin did not have enough evidence at the time to convince many scientists
- it took 50 years after Darwin’s theory was published
to discover how inheritance and variation worked.

- Unlike Lamarck's theory, Darwin's theory of evolution
accounted for the continued presence of simple organisms.

- Lamarck’s
theory
- theory involved two ideas: A characteristic which is used more and more by an organism becomes
bigger and stronger, and one that is not used eventually disappears. Any feature of an organism that
is improved through use is passed to its offspring.
- Lamarck's theory cannot account for all the observations made about life on Earth. For instance, his
theory implies that all organisms would gradually become complex, and simple organisms disappear.
Anmerkungen:
- THE BIG PROBLEM
