WHERE DO FRECKLES COME FROM EXACTLY

Freckles are passed down from parents. If your parents have freckles then you have a high chance of getting them during Summer. The gene, MC1R and the environment controls the size, colour and the pattern. The sun is capable of changing the freckles.


The gene MC1R is associated with causing red hair and freckles. The MC1R lies around the melanocytes on the skin and helps set a balance of pigments in the skin.


If one parent has freckles and the other doesn't then you may have a less chance of such prominent freckles compared to someone who's parents both have freckles. 80% of redheads have MC1R.


From my research there seems to be some sort of debate about who brought the red hair and freckles to Ireland, the Celts or the Viking?
Professor Donna Heddie says that the Vikings were mostly red instead of blond, in terms of hair colour.  She mentioned that if you look where red heads came from it's almost mapped to the Viking's voyages. 
But Jim Wilson disagrees, he says while though the Vikings did contribute to the red head gene, he thinks it's more likely came from the Celts because of the pattern of the redhead gene in the British Isle is more consistent.


The red hair gene, according to experts, it was developed 50,000 years ago. 

And the pale skin part of it is because where the celts and vikings were from they didn't see so much sun so when they did see sun they would absorb vitamin D faster then people who would see the sun more. Therefore they became more sensitive to the sun, contributing an uneven pigmentation ie, freckles.

THE LEGEND BEHIND FRECKLES The old legend has it that the Gods saw the sons of Adam building a tower in Babylon, and they weren't happy about this, so they gave people different languages in the hope to confuse them and also to make the Sons of Adam to forget who they were. The Gaels were from an island up north, on the Atlantic (Ireland), they were given the language Gaeilge. The Gods were aware that the Gaels were unable to see the stars and heavens from their land, so they sprayed the Gaels with dust, so they wouldn't forget about the stars and heavens. The dust was freckles called 'briciní' which is Irish for little stars, the freckles are a map of the universe so that the Gaels would remember the stars and heavens even if they couldn't see them from their home. According to an Ancient Roman naturalist, Pliny the Elder said that if you were a woman with 'lenticula' which means freckles on the skin. It looked as if you are unclean and impure. If

THE TYPES OF FRECKLES There are two types of freckles. They are called, ephelides and the other lentignes. The crucial difference between them is that, ephelides are your normal freckle they appear around Summer time and once Winter comes round they fade. They are usually around the same size of the head of a nail. Where as, lentignes are bigger and much darker and they also don't fade in Winter. Lentignes arise when the skin is also exposed to the sun, they also have more irregular sides to them. They increase in number as you get older. https://commons.wikimedia.org/wiki/File:Smiling_model_with_freckles.jpg Malignant melanoma is skin cancer, it is of a result of skin being over exposed to sunlight and the UV rays have damaged skin cells and therefore cancer forms, a sign of skin cancer is an odd looking, dark spot on the skin with irregular sides. It is so crucial to be able to tell the difference between a malignant melanoma and your normal freckles. If the freckle i
