What Will Humans Look Like In The Future?
It's no shocker that us mammals are expected to evolve as centuries whizz by, much like our favourite little creatures in our Pokémon Go app!
But how so?
Approximately 200,000 years ago, modern humans evolved from archaic humans, which pinpoints the start of Homo Sapiens. The start of you and I. And boy have we evolved. However, believe it or not, us humans have only been around for as little as 0.004% of Earth's history, so imagine the evolution and development that is to dawn on us as we remain on this planet for even longer.
We'll All Look More Brazilian
Since 1917, when Chalk's Ocean Airways was the first airline to operate international flights, it's been pretty easy to get from one country to another. And with that comes the beautiful mixture of cultures, races, religions and genes.
Dominant traits are likely to...well, dominate as the recessive genes in our DNA are likely to be much more rare since a recessive gene and a recessive gene both need to pair up to say, make blue eyes (which is a recessive trait). That is why, there will be a decrease in people with blue eyes, as already shown significantly since just 100 years ago, when more than half of US White Americans had the blue eye trait to the present, where only about 1 in 6 US White Americans have blue eyes.
And not only that but recessive traits such as freckles and blonde hair are very likely to decline too. Hitler would hate to hear that.
Although, with these slight losses come gains. With our genes mixing up and people disregarding skin colour, opinions, perspectives as way of determining who they should mix and socialise with, our Earth will slowly emerge into a world of acceptance and an increase in potential peace among different cultures and races. Much like community cohesion, if different people from different countries and background mix together like in a blender, we'll all understand and appreciate different cultures a lot more, with a much more open mind. This could decrease the amount of racism and discrimination.
In fact, with the mixing of skin colours, it is expected for most humans to eventually all have a caramel complexion, and more specifically, look more Brazilian.
On the other hand, with everyone mixing and gradually becoming similar, this could also decrease the amount of cultural diversity and differences in society, which isn't too positive as this could potentially lead back to a time of division and "superior" races.
Decrease in the Size of Teeth
As seen in the image below, the evolution of our ancestors' jaws have decreased and it doesn't take a scientist to realise that.
Over time, us humans have grown accustomed to enjoying foods simply bought from the shops, prepared in restarants, cooked in the comfort of your own kitchen or even from your own gardens or land. But we've definitely strayed from the old hunting and attacking prey like lions. So, inevitably, our foods are much softer and easier to chew and digest, which is why the strength and size of our jaws have decreased. We don't depend on it so much.
And something we definitely do not depend on anymore are wisdom teeth. A while back, wisdom teeth were used as extra power to chew rough, harder foods like nuts, roots, meat, etc. So it's very possible for all humans to evolve away from wisdom teeth.
In addition to this, our teeth are expected to get smaller. With our diets becoming more nutrient rich, there is less of a need to eat as much, so our teeth are not being used as much.
Possibly Weaker Immune Systems
As much as there are fairly positive advantages to our development and evolution, there will be disadvantages, too.
As we advance in technology and science and our brains begin to absorb more information and process more knowledge about or world, medicine will, for sure, develop significantly and improve our lifestyles.
I'm sure we'll one day find the cure for all cancers and push up our life expectancies by a few...decades maybe. But, this makes humans more dependant on medicines and our bodies will rely on these medications to survive and try to live normally instead of living organically.
This is all fine for the time being but imagine what could happen in the far future.
Human bodies may not even be able to function on its own without medicines and technology since they may get so used to working artificially.
Picture it like consuming a cup of coffee every morning. Every morning, you may like to start your day with a cup of coffee, just to boost your energy up for the day. But at a certain point, you'll need to drink that cup of coffee everyday since your body will be so used to it and so used to it providing you energy for the morning.
That's what our immune systems may be like in the future. Our bodies may depend of supplements and medication for the rest of our lives.
Changes to Our Fingers and Toes
Our toes are on our bodies primarily for climbing, as well as our hands. However, since we don't usually climb, our toes are not as useful as they once were to our ancestors.
Our big toes' purpose are for balance and stability when standing and walking so I wouldn't imagine losing. But what are our little toes good for? To stub against the legs of tables and chairs, inflicting pain on us for what seems like eternity?
Actually, our little toes are pretty much useless and it won't be a shock if they happen to disappear from our bodies.
A different idea about the changes to our fingers and toes comes from paleoanthropologist, Dr Matthew Skinner, who has said that with global warming, the ice caps will melt, increasing sea levels, forcing humans to survive underwater. With this, he believes we'll actually see a lengthening in our fingers as well as webbed fingers and toes like ducks, so they we can have a increased chance in surviving in an underwater community.
