Explains how and why life changes through time. Problems with models: often a confusion between models and reality, constrain our mental conceptualizations of the natural world, limit how we experiment with a biological system. Illustrates correlations: strong associations are not evidence of causation, ex: having a mutation and having a disease; lung cancer and smoking. Individuals, populations are compared that differ in one or more condition: no controls, ex: seedlings growing in a forest in high vs. low sunlight, significant differences between groups in comparison studies are not evidence of causation. Thought experiment: using our brains to test a hypothesis using only pre-existing knowledge, ex: richard alexander predicted what a eusocial vertebrate would be live if it did exist.
