The main reason for this is that the colours that the human eye perceives, are actually reflected or refracted light waves; the reflected light waves according to one of two different colour systems. To understand colours is, therefore a hybrid science between biology, optics, chromatics, chemistry, physics, psychology and genealogy.The reason why conditions such as leucism and melanism have a number of different explanations, some completely wrong, and why a condition such as xanthocronism has been created by scientists while it actually does not exist at all, is because of scientists trying to explain the forming and display of colours in birds from different scientific bases. To emphasise this viewpoint: You cannot explain the formation and display of biological, pigment based colours by optics, and you can not explain optically created colours biologically. And in birds colours are created and perceived biologically and optically!In studying bird colours for more than 40 years, amongst others as a bird breeder, I have made a number of new discoveries related to the creation and display of colours in birds, and especially changes in colour. What I have discovered will explain all the different bird colours seen by bird watchers in nature, and also point scientists in a direction to revise and perfect the Science of Avichroma, the name that I have given to the science of studying bird colours.To relay the information to Mr. Average, I make extensive use of simplified graphics and illustrations. Bear in mind that these do not correspond exactly to what you will see under, for instance, an electron microscope in the cell of a bird, but has the purpose of explaining the different conditions and processes to the layman.I also try to explain each aspect or process in simplified steps and unscientific language, and in an order where the knowledge required from the first step, is mostly required and essential in understanding the next step(s).With the knowledge contained in this book, birdwatchers will now be able to fully understand the differently coloured birds of the same species that they may encounter in the field.Scientists can now also incorporate the new discoveries abour colour and genetic defects in birds as described in this book, in genetic science and adapt their present knowledge bases, theories and definitions where required. They can totally rethink dominance and recessiveness, they can kiss the old theory of xanthocronism goodbye, and look anew at the pure definitions for leucism and melanism. They can also rethink the theory of spontaneous mutations and replace it with the laws of colour changes as a result of specific, identifiable, predictable and calculable colour defects. They can transfer the knowledge obtained from this publication, to other groups of living animals such as fishes, insects and even plants. Breeders breeding animals such as dogs, cats, horses and birds, will also benefit from this knowledge.Not only does this publication establish Avichroma as the Sciene of Colour in Birds, but it can contribute immensely to the expansion of knowledge in other scientific fields as well.The author is proud to submit the results of 40 years of intense study to you, the reader, in this publication....9781005040765_Herman van Niekerklibro_electonico_5bc4d5a4-84b4-3838-8bab-9a2fb4d919e7_9781005040765;9781005040765_9781005040765Herman vanInglésMéxicohttps://getbook.kobo.com/koboid-prod-public/smashwords-epub-6d214e27-5964-4b09-ba30-8de5ed3bbea3.epub2021-12-11T00:00:00+00:00Herman van Niekerk
