Skin Color Measurement

English: “A Venerable Orang-outang”, a caricature of Charles Darwin as an ape published in The Hornet, a satirical magazine Deutsch: Man sieht Darwin als Affen dargestellt, was eine Anspielung auf seine Evolutionstheorie sein soll. Seiner Meinung nach entwickelten sich die Menschen aus den Affen, was damals eine völlig neue Vorstellung war. (Photo credit: Wikipedia)

Today I read an interesting article about the evolutionary significance of colour vision. (Why am I getting into evolution so much? Darwin’s ghost is haunting me!) The author believes that colour vision evolved to sense oxygenation modulations in the hemoglobin under the skin. Interesting theory indeed.

I (We) have been working on an algorithm to measure skin colour for some time. Accurate skin colour measurement may be a useful tool in cosmetic dermatology though it may test the claims of many fairness cream manufacturers! The algorithm is far from perfect.

BTW are you ready to test the next fairness cream?

Today I read a well structured and exceptionally comprehensive review of the theories and evolutionary significance of ageing. The author argues that ageing may not be a fortuitous consequence of post-reproductive decline of evolutionary selective pressure as “Evolutionary Theories of Ageing” (ETA) suggest but a phylogenetically conserved, signalling pathway controlled inexorable progression towards death. As Anti-ageing and its pragmatic cousin graceful-ageing are pivotal to cosmetic dermatology, we should be aware of the evolutionary significance of ageing. The author substantiates, based on 400,000 published scientific papers, out of which 4000 have been referred in this monumental paper, that ageing may not even be a group selection process due to resource limitation but a individual germ-soma conflict over the utilization of resources. A transgenerational conflict between germline cells and soma is happening inside you!!
