PHL357H5 Lecture Notes - Lecture 18: Mate Choice, Mutation, Group Selection
Document Summary
The issue as far as hull is concerned: according to aristotle there"s a different between individuals and characteristics. Classes are defined by things that never change. A particular independent (lump of clay) may be a triangle one time or a square another. Squareness and triangularity are forever, but they can be made by different things. Hull wants to say that species are individual and not charcteristics: put into biological terms. On one hand you can say chimps evolve, but this isn"t a conclusive consideration. Does not show an individual or a class. 2 arguments: 1) if characteristics don"t change and chimp changes; therefore chimp is not a, 2) against argument #1 characteristic. Consider a population or class (population of brampton)we can say that the population has become richer over the last 20 years. All we say here though is that there were 2 different groups tht occupied the different times, not individuals but populations.
