4.2 Naturalism and reductive explanation

There is a widespread commitment among contemporary philosophers and scientists to a naturalistic view of the world. In broad terms, naturalism is the view that everything is scientifically explicable – to put it crudely, that there are no miracles. (Note that I am using ‘naturalism’ here for a metaphysical position – a view about the nature of the world.

Summary of Section 5

  1. The stability of DNA makes it suitable as a store of genetic information.

  2. The susceptibility of DNA to chemical damage allows mutations to arise.

  3. DNA damage can occur due to chemical interactions with reactive molecular species or irradiation. If not repaired, such damage results in base loss or mutations due to mispairing in replication.

1.6 Conclusion

This course has presented an overview of the ways in which organisms living in temperate habitats are adapted to survive the winter. The course has shown how a limited set of environmental changes associated with the onset of winter can lead to a diversity of adaptations and therefore a large diversity of species.

On the basis of the examples discussed in this course, we can identify four factors that contribute to the diversity of adaptive strategies for coping with winter.

These are three words that mostly evoke warm and positive feelings. In Activity 1 you're asked to think about opposite points of view.
