Study Notes
Evolution Misconceptions
- Evolution is not a random or chance process; natural selection is a selective process that leads to better adaptation to the environment.
- Genetic drift, although a chance process, contributes to evolution.
- Evolution involves some chance processes, but it is not a chance process as a whole.
Falsifiability of Evolution
- A complex adaptation that couldn't be broken down into small, adaptive steps would disprove evolution.
- A complex adaptation in one species that benefits only another species or a Precambrian rabbit would also disprove evolution.
Predictive Power of Evolution
- Darwin predicted that fossils from early human evolution would be found in Africa, and his prediction was later confirmed.
- The discovery of the naked mole rat, an underground, inbred population of rodents, confirms the predictive power of evolution.
- The Sleeping Beauty transposon was developed using predictive logic, reconstructing a functional transposon from broken copies in vertebrate genomes.
Rate of Evolution
- Evolution can occur rapidly, as seen in bacterial resistance to antibiotics, which can evolve in a patient over the course of treatment.
- The differences between a pug and a wolf can evolve in a few thousand years of selective breeding.
Evolution of Novelty
- The Lenski experiment refutes the idea that evolution cannot produce novelty; mutations can alter old things to make new ones or combine them in novel ways.
- Snakes evolved venom as a modification of existing enzymes, an example of evolutionary novelty.
Goals and Direction of Evolution
- There is no end point to evolution; natural selection has no foresight and can only work with variants within a population at any one time.
- Evolution can lead to loss of complexity, as seen in the degeneration of cave fish eyes and the reduction of parasitic animals' complexities.
History of Evolutionary Thought
- Erasmus Darwin, Buffon, Lamarck, and Zhuangzi all contributed to the idea of evolution before Charles Darwin.
- Darwin's work has been built upon, improved, and refined since his time.
