I have also done a certain amount of licensed work, illustrating characters such as Postman Pat, Bill and Ben and Sesame Street. You can think of a photon as a drunk person walking through a forest. The drunk person enters the forest and walks into a tree, D’oh!, changes direction (scatters) and walks another short distance and into another tree, D’oh! D’oh! D’oh! D’oh! …. and before you know it the drunk person exits the forest in a random place going a random direction.

And if we’re finding new species of primates, then who knows how many new species of small mammals or lizards or insects, just to name a few, might be out there. There’s certainly a lot of undiscovered biodiversity in this region.” White, E. C.; Dikangadissi, J.-T.; Dimoto, E.; etal. (2010). "Home-range use by a large horde of wild Mandrillus sphinx". International Journal of Primatology. 31 (4): 627–645. doi: 10.1007/s10764-010-9417-3. S2CID 44740032. For instance, the green monkey, a vervet native to West Africa and the West Indies, has genitalia that turns a pale blue or even white in adulthood. Baynes, Thomas Spencer (1833). The Encyclopaedia Britannica A Dictionary of Arts, Sciences, and General Literature: Volume 15. University of Michigan. pp.476–477.The Lesula ( Cercopithecus lomamiensis) seems to have escaped previous scientific notice because of its remote habitat, which was largely unexplored by professional biologists until recently. Some authorities have divided mandrill populations into subspecies: the northern mandrill ( M. s. sphinx) and the southern mandrill ( M. s. madarogaster). A proposed third subspecies, M. s. insularis, was based on the mistaken belief that mandrills are present on Bioko Island. [14] [15] The consensus is that mandrills belong to one subspecies ( M. s. sphinx). [16]

Goods that by reason of their nature, cannot be returned - (Items such as underwear, where the 'hygiene patch' has been removed, or cosmetics where the seal has been broken). To understand how photons move through a complex tissue like skin, lets compare a red photon with a blue photon as it hits two tissue layers. Tissue “A” is on top, and Tissue “B” is underneath. If layers A and B were both white (like milk), they would reflect red and blue photons equally and you would see both colors. Major discoveries like this are still possible, mainly thanks to dedicated field biologists like the Harts,” says Eric Sargis, professor of anthropology at Yale and a co-author of the paper.

It is well worth joining us, there is so much more once inside.Mandrills are large primates closely related to the baboon. These animals inhabit the tropical forests of Africa and are monkeys with blue butts. Additionally, the mandrill is the largest non-ape primate. It is arguably the most colorful, with a trademark bright red and blue face and a very bright and colorful butt. These are secondary sexual characteristics, present in both sexes but much more vibrant in males. Scientists believe that they use this feature to attract mates and intimidate rivals.
