El preformismo concibe el desarrollo del embrión a partir de la existencia de un embrión preformado contenido en el espermatozoide o en el huevo; mientras que la epigénesis considera que este se origina a partir del desarrollo de un principio amorfo, como consecuencia de los cambios que se producen con la fecundación.

Comenzando al menos con Aristóteles, los científicos han tratado de ordenar los diferentes tipos de animales y plantas a lo largo de una escala lineal, llamada scala naturae (en latín, “escala de la naturaleza”; Lovejoy, 1936 ). La métrica de esta escala suele ser la similitud entre una especie determinada y el Homo sapiens, de modo que los animales más similares a nosotros se colocan en los peldaños más altos, mientras que las especies progresivamente más diferentes de nosotros se asignan a posiciones sucesivamente más bajas a lo largo de la escala. Un gran problema con esto (p. 11) es que la "similitud con los humanos" es una medida altamente multidimensional, y diferentes dimensiones producen diferentes clasificaciones de especies. Por ejemplo, las clasificaciones basadas en presunta inteligencia podrían colocar a los delfines en lo alto de la escala, mientras que las clasificaciones basadas en el modo de locomoción elevan a las aves no voladoras (por ejemplo, kiwis y avestruces) muy por encima de los delfines y otros mamíferos acuáticos. Independientemente de la medida utilizada, los partidarios del punto de vista de scala naturae tienden a equiparar los aumentos en la similitud con los humanos con el "progreso" evolutivo.

Estamos tan acostumbrados a ver el mundo a través de nuestros magníficos ojos humanos que es difícil imaginar cómo sería el mundo a través de los ojos de cualquier otra especie.
MiOpinion Siempre que se estudia la visión en Biología del color es indispensable considerar el de percepción del organismo estudiado, pues su visión NO es igual a la nuestra y esto generalmente puede ser un problema, porque genera una visión antropocéntrica e irreal del problema.

Cada aspecto de la visión, desde las proteínas de opsina hasta los ojos y las formas en que sirven al comportamiento animal, es increíblemente diverso. Solo con una perspectiva evolutiva se puede comprender y apreciar plenamente esta diversidad. En esta revisión, describo y explico la diversidad en cada nivel y trato de transmitir una comprensión de cómo el origen de la primera ops en hace unos 800 millones de años pudo iniciar la avalancha que produjo la asombrosa diversidad de ojos y visiones que vemos hoy. A pesar de la diversidad, muchos tipos de fotorreceptores, ojos y roles visuales han evolucionado varias veces de forma independiente en diferentes animales, revelando un patrón de evolución ocular estrictamente guiado por limitaciones funcionales e impulsado por la evolución de comportamientos gradualmente más exigentes.

Birds and mammals have only one pigment cell type, the melanocyte, producing the pigment melanin (although in different shades) that is secreted into the skin or feathers and hairs.

In contrast, basal vertebrates such as fish, amphibia and reptiles develop several chromatophore types producing different colours. In these animals, colour patterns arise as mosaics of chromatophores distributed in the hypodermis of the body, and the epidermis of scales and fins (Box 1).

Although colour pattern formation has fascinated scientists since the beginning of modern biology [3], the field is still dominated by theories rather than detailed knowledge of the underlying molecular, cellular and developmental events.
-
Vertebrate colour patterns are composed of specialised pigment-producing cells, the chromatophores. These originate from the neural crest, a transient primordium of multipotent cells located at the dorsal neuroectodermal ridge from which progenitor cells emigrate to develop a variety of structures and tissues [2]. Neural crest is a developmental innovation that allowed vertebrates to get both large and colourful. Other neural crest-derived structures include elements of the skull and jaw, the neurons of the peripheral nervous system and glia.

In short, colour patterns are of high evolutionary relevance as targets of natural as well as sexual selection.

For example, many animals have dorsal coloration that reduces predation through crypsis or aposematism but ventral coloration that is used for short-range intraspecific signaling [e.g., (80)].

For example, great reed warblers (Acrocephalus arundinaceus), frequent hosts of the common cuckoo (Cuculus canorus), show context-dependent rejection of foreign eggs (47) (Fig. 3). Mimetic eggs are typically accepted by these hosts, but in the presence of a cuckoo near the nest, or after exposure to a nonmimetic cuckoo egg, these same eggs are often rejected. Understanding how the host cognitive system adjusts its recognition thresholds to accommodate increased risks of cuckoo parasitism needs attention (48, 49).

Genes underlying color variation offer insight into the predictability of evolution. Convergent phenotypes commonly arise in parallel; the accurate characterization of color phenotypes has revealed independent changes in similar genetic mechanisms, leading to phenotypic similarity between species (19). For example, changes in pigmentation from weakly to deeply melanic can be controlled by parallel genetic changes in highly divergent lineages, such as in the case of the Kit ligand in pigmentation of sticklebacks and human skin; Oca2 in pigmentation of snakes, cavefish, and humans; and MC1R in numerous birds and mammals (19)

This will be a critical foundation for future understanding of ordered self-assembly in colored biological materials, from β-keratin in birds’ feathers (5)

BACKGROUNDThe interdisciplinary field of animal coloration is growing rapidly, spanning questions about the diverse ways that animals use pigments and structures to generate color, the underlying genetics and epigenetics, the perception of color, how color information is integrated with information from other senses, and general principles underlying color’s evolution and function. People working in the field appreciate linkages between these parallel lines of enquiry, but outsiders need the easily navigable roadmap that we provide here. ADVANCESIn the past 20 years, the field of animal coloration research has been propelled forward by technological advances that include spectrophotometry, digital imaging, computational neuroscience, innovative laboratory and field studies, and large-scale comparative analyses, which are allowing new questions to be asked. For example, we can now pose questions about the evolution of camouflage based on what a prey’s main predator can see, and we can start to appreciate that gene changes underlying color production have occurred in parallel in unrelated species. Knowledge of the production, perception, and evolutionary function of coloration is poised to make contributions to areas as diverse as medicine, security, clothing, and the military, but we need to take stock before moving forward. OUTLOOKHere, a group of evolutionary biologists, behavioral ecologists, psychologists, optical physicists, visual physiologists, geneticists, and anthropologists review this diverse area of science, daunting to the outsider, and set out what we believe are the key questions for the future. These are how nanoscale structures are used to manipulate light; how dynamic changes in coloration occur on different time scales; the genetics of coloration (including key innovations and the extent of parallel changes in different lineages); alternative perceptions of color by different species (including wavelengths that we cannot see, such as ultraviolet); how color, pattern, and motion interact; and how color works together with other modalities, especially odor. From an adaptive standpoint, color can serve several functions, and the resulting patterns frequently represent a trade-off among different evolutionary drivers, some of which are nonvisual (e.g., photoprotection). These trade-offs can vary between individuals within the same population, and color can be altered strategically on different time scales to serve different purposes. Lastly, interspecific differences in coloration, sometimes even observable in the fossil record, give insights into trait evolution. The biology of color is a field that typifies modern research: curiosity-led, technology-driven, multilevel, interdisciplinary, and integrative.
