Did you know how you look is determined by both your genetics and the environment your ancestors were exposed too?
Did you know that the follicle shape of your hair determines its texture and the size of the follicle the thickness of the hair?
Ever wonder why some ethnicities have straight hair and others have curly?
Curly hair like Africans (Blacks) have flat follicles which causes the hair to curl; we also have wider nostrils.
These features developed along with our skin color because the environment was hot and sunny and the scalp needed protection, the nostrils also needed to be wide to bring in a lot of air to cool the brain.
We also produce high amounts of melanin (natural sun screen) needed for living in a sunny environment.
It's like men developed longer eye lashes than women because they needed them for protection of the dust and winds while out hunting!
Europeans (Whites) on the other hand developed from those that left Africa and settled in a cold weather environment and had to develop long stringy hair to cover the neck and provide warmth and they needed narrower noses because they needed to warm the air before it reached the brain!
The first Europeans were the Grimaldi men from Africa (Alkebulan).
There is much speculation and debate as to if their development (Whites) were the result of albinism (which occurs in every species on the planet) or from Homo sapiens interbreeding with Neanderthals.
Your genes carry the instructions for the growth and development of your body.
However, your phenotype is influenced during embryonic development and throughout your life by environmental factors.
Environmental factors are many and varied and include diet, climate, illness and stress.
With the PTC tasting example, scientists estimate that the gene controls about 85% of the ability to taste.
Environmental factors that play a role include how dry your mouth is or how recently you have eaten.
The degree to which your phenotype is determined by your genotype is referred to as ‘phenotypic plasticity’.
If environmental factors have a strong influence, the phenotypic plasticity is high. If genotype can be used to reliably predict phenotype, the phenotypic plasticity is low.
Overall, the amount of influence that environmental factors have on your ultimate phenotype is a hotly debated scientific issue.
It is often referred to as the ‘nature (genes) versus nurture (environment)’ debate.
Scientists commonly study monozygous (identical) twins to investigate the genotype/phenotype relationship.
In conclusion, your genotype or genetic make-up plays a critical role in your development.
However, environmental factors influence our phenotypes throughout our lives, and it is this on-going interplay between genetics and environment that makes us all unique and constantly evolving!
OUR MOST CRITICAL EVOLVING SHOULD BE IN THE AREA OF OUR SPIRITUAL DEVELOPMENT!
Then we can learn to appreciate and embrace our differences!
But understand many have a skewed version of beauty based on years of indoctrination in a society that has Institutionalized Racism!
