- Evolution has led from amoebae to blue whales and from algae to giant redwoods.
So what might it do in the future? What species might evolve in the next ten million years? How will evolutionary processes change as a result of human innovation and what are the risks of us getting it disastrously wrong? What might evolution look like if we ever set up home on another planet, or if inhabitants of other planets arrive here?

This man makes me wish I'd been certified as a middle/high school science teacher instead of a social studies one. But you can bet that I'm stealing as much of this as possible.
I loved the Evolution series. Robin May is just brilliant. I'm looking forward to hearing more from him
My favorite lecturer!❤
he’s sooo hot
Always make my day enjoy every minute of it❤
This was great
Would like to refute a point. UK gets much lower UV exposure. Therefore paler skin is an evolutionary advantage and that’s why people living in higher latitudes have relatively lighter pigmentation, primarily to do with Vitamin D utilisation
N.B - eskimos is an exception because of reflected UV from snow
No , Eskimos have not had time to adapt. They have not been around that long. Also thet get vitamin D from fish. Only the European farmers had vitamin D deficiency.
Eskimos still hasn’t acquired lighter pigmentation since they have a ready source of vitamin D in the fish. It’s also likely acquiring lighter pigmentation would put them at an evolutionary disadvantage in view of the reflective UV from the snow. However perhaps if fish was not a ready source of vitamin D , natural selection would have determined whether they should have lighter pigmentation to get more vitamin D from the reflective UV. My initial point was Mr. May gave wrong information saying UK has high UV exposure.
This is the most popular theory, but there are arguments against it, and alternative theories exist. This is still an unsettled question.
Que sera, sera.
I read somewhere that due to the availability of caesarian operations (mainly in the west), there is a creeping Lara-Croft-isation of women's physiques, i.e. slim-hipped women who may have died in childbirth in earlier generations are now surviving and passing on their slim-hipped genes. May be absolute nonsense, but comments from slim-hipped women and otherwise are appreciated :-)
Lara Croft has an hour glass figure but usual hips.
You might as well add children that had rather large heads at birth to that equation. And of course the actual reason for most cesarean sections being children trying to come out feet first or with entangled umblical chords.
@@molochi I had a slim-hipped colleague who chose to have all of her three children delivered by c-section. Apparently further pregnancies after a c-section birth can be risky.
Where did you read that, in The Sun?
@@SirAntoniousBlock No, I checked. It was a BBC article from 2016. Search for "Caesarean births 'affecting human evolution".
With 8 billion people on earth now, shouldn't their be more mutations than before?
Pretty depressing picture for human evolution. Our medical care keeps most alive through the breeding ages. The more successful (in a technology age) are not breeding to any extent. Firstly due to education demands and then career aspirations. I suspect those without education/careers are breeding at a higher rate. I read that IQ is in a downward trend which does not bode well for the long term. Perhaps intelligence is no longer a requirement for the species......
We may get two types of human. Rich and poor. The rich will be tall and magnificent and highly intelligent (because they can afford 'perfect' children thanks genetic planning) and an underclass of short, brutish, slaves.
I guess that might be the dream of some.
Excellent point. Maybe like the two races described in the H.G. Wells's novel ''The Time Machine''. Regardless, there is already an 'underclass' who cannot afford private dental treatment because the National Health Service has next-to-none NHS dentists on their books. The rich, however, don't need an appointment to see their ''orthodontist'' (just a fancy term to describe a 'cosmetic' dentist).
Bottom line here. You're poor, your teeth fall out. You're rich, you can buy a perfect set of pearly-whites.

If we only consider the expertise in the genetics field as it is now, the tools and ability to deploy the knowledge will slowly become cheaper and more accessible (think cars, flat screen TVs, different kinds of medical procedures). The way middle-class folks live in the Western world today would look unimaginably lavish to those living 50-75 years ago, what with all the electronics and appliances, but it's because the tech became more efficient and cheaper to make and the knowledge easier to deploy.
Assuming these patterns continue, the lower classes aren't going to be left here in the first half of the 21st century, while the rich exponentially accelerate in tools and medicine over the next few centuries. The "less new" new techs and procedures will diffuse down while the elites keep advancing. The elites always take 2 steps forward for every 1 of the lower class, but I think it would take a dedicated eugenics program to really keep the lower classes down in the way this comment suggests
@@noahwinberry2475 It'll happen more organically. The rich will not breed with the poor, and worse, will be able to produce exponentially more exceptional children. Perhaps with expensive electronic chips that perfectly balance their diets, help choose their romantic partners and screen for the early signs of disease. No eugenics programmes required. It'll be the haves and the have nots - like we have now - except the haves will have access to an awful lot more. At a price only they can afford.
