George Bauer; Georgius Agricola (DE) wrote the first book on physical geology, , which is important because of its descriptions of wind and water as powerful geological forces, and for its explanation of earthquakes and volcanic eruptions as produced by subterranean vapors and gases heated by the Earth's internal heat. His book (), also published in 1546, is considered his most important contribution to paleontology. This book is not restricted to what we call fossils today: the Latin word meant anything dug out of the ground, and Agricola's book included descriptions of all kinds of minerals, gemstones, and even gallstones, in addition to what we would call fossils now. Agricola's work summed up what the ancient Greek and Roman authors had written about minerals, and included a list of a hundred ancient authors whose works Agricola had consulted -- but Agricola was not afraid to contradict the ancients' opinions if they did not fit with his own experience. His work represented a major advance over previous writings on rocks and minerals in that it classified them, not alphabetically or by their supposed mystical powers, but by simple physical properties: "Thus minerals have differences which we observe by color, taste, odor, place of origin, natural strength and weakness, shape, form, and size." Agricola gave standardized names to various minerals, and not only recorded their appearance but the localities where they could be found. He also noted how the same fossils might have different colors and appearances in different places. Although Agricola's work included no pictures, his descriptions of fossils are often instantly recognizable. In his book () Agricola noted that rocks were laid down in definite layers, or strata, and that these layers occurred in a consistent order and could be traced over a wide area. This observation of Agricola's was one of the first contributions to stratigraphic geology, and one that would become important in understanding the arrangement and origins of the rocks of the Earth.

The most widely accredited explanatory model, the heterozygote superiority overdominance hypothesis, makes the assertion that individuals with trichromatic vision females heterozygous for the LM opsin have a fitness advantage relative to homozygous genotypes, since redgreen chromatic discrimination is useful in foraging for reddish, conspicuous fruits – or young leaves for sociosexual signaling via pelage color or patterns of blood flow or for detecting items of importance in the environment, including sympatric primate species and predators such as tropical felids , . Indeed, we have shown that trichromatic females in a population of wild whitefaced capuchins Cebus capucinus are more accurate in selecting ripe, reddish fruits than are males or dichromatic females . However, that improved accuracy did not translate to a net increase in feeding rate, perhaps because dichromats used behavioral compensation, had improved color perception in certain light environments or increased their reliance on other sensory modalities, such as olfaction –. Similar results for a sympatric population of polymorphic spider monkeys, documenting no difference in fruit feeding rates between dichromatic and trichromatic monkeys, are reported by Hiramatsu etal. , , and by Vogel etal. in their study of a neighboring population of whitefaced capuchins.

Thomas Young (GB) was the first to insist that force can no longer be expressed as a simple mathematical formula of mass times velocity squared and suggested in its place the term for this arithmetical product, adding that some method must be discovered to define the proper relation between work and heat. In the same lecture series he suggested that Dalton’s color blindness was probably due to the absence of the retinal resonator for red (). : The seeds of the theory of specific nerve energies can be found in Thomas Young’s work. This theory, which would blossom within the next few decades, stressed the importance of stimulating specific receptors and nerves for perception. Unfortunately, it is believed that Young never realized the full significance or the implications of his theory. Still, it was Young who may have been the first to explain three primary colors on the basis of visual physiology as opposed to the physics of light. As he put it, trichromatic theory is based “not in the nature of light, but in the constitution of man.”

Francis Bacon, a philosopher and Lord Chancellor of England, popularized the scientific method and thus lead a scientific revolution. One should begin with data, not faith, and then propose a testable hypothesis to explain those facts. This method of reasoning from the particulars to the general is known as induction. He emphasized the importance of experimentation as a way of testing ideas. Bacon also warned that to achieve accurate thinking we must guard against belief systems (Idols) common in or culture. He characterized the idols as: the Idol of the Tribe (community beliefs), the Cave (individual beliefs), the Marketplace (semantic communication problems), and the Theatre (deduction from believed but unproven premises) ().

The leading explanatory model for the widespread occurrence of color vision polymorphism in Neotropical primates is the heterozygote superiority hypothesis, which postulates that trichromatic individuals have a fitness advantage over other phenotypes because redgreen chromatic discrimination is useful for foraging, social signaling, or predator detection. Alternative explanatory models predict that dichromatic and trichromatic phenotypes are each suited to distinct tasks. To conclusively evaluate these models, one must determine whether proposed visual advantages translate into differential fitness of trichromatic and dichromatic individuals. We tested whether color vision phenotype is a significant predictor of female fitness in a population of wild capuchins, using longterm 26 years survival and fertility data. We found no advantage to trichromats over dichromats for three fitness measures fertility rates, offspring survival and maternal survival. This finding suggests that a selective mechanism other than heterozygote advantage is operating to maintain the color vision polymorphism. We propose that attention be directed to field testing the alternative mechanisms of balancing selection proposed to explain opsin polymorphism nichedivergence, frequencydependence and mutual benefit of association. This is the first indepth, longterm study examining the effects of color vision variation on survival and reproductive success in a naturallyoccurring population of primates.
