1)melanogenesis doesnt start w/ an ENZYME...it starts w/ a HORMONE called MSH...sooo i choose to ignore anyone who cant comprehend that...HORMONES send out messeges...Enzymes cant do this
its VERY important you understand that
and...there is no such thing as "junk" DNA (if that was what u were trying to say)...and nooo thats NOT what theyre saying
last i checked...fungus was between the plant and animal kingdom sooo why dont you FIRST learn how fungus grows (what type of energy) it needs..then you MIGHT understand the link between mtDNA eve, FUNGUS, MELANIN, LIGHT, HEAT, CARBON, ENERGY... jus to name a few
and HOW someone that once was able to produce melanin in mass abundance..could eventually LOSE that ability
BUT your NEVER going to understand if you cant understand the FUNDAMENTALS of melanogenesis
