Why Are FPs Important? “….in seeking regularity and focusing on the most salient features in their environment, in order to endure and thrive, animals have empirically discovered the laws of nature.” Kalmijn, A.

Philosophical Transactions of The Royal Society of London series B, 355(1401), 1135-1141.
