Monarchs and Milkweed Quotes

“Distinguishing between correlation and causation is critical to our understanding of the biology and conservation of monarchs and milkweeds. Turning back to our study of chocolate: countrywide spending on science also correlates with per capita income, the latter of which correlates with chocolate consumption (at least in the Western world). Even so, I would happily participate in a controlled study to determine the influence of chocolate consumption on scientific discoveries.”
