We often think of evolution as ‘something that happened’ in the past. But of course, evolution is a constant, powerful process and one that is often unleashed by human behaviours.
Often this is deliberate, we’ll look at how artificial selection has shaped our crops, livestock and domestic pets, and we’ll find out how modern science is uncovering the genetic changes that lie beneath. But sometimes human behaviours unleash powerful and altogether less welcome evolutionary forces…join us as we uncover them together!
This lecture was recorded by Robin May on 20th March 2024 at Barnard's Inn Hall, London
Robin is Gresham Professor of Physic.
He is also Chief Scientific Adviser at the Food Standards Agency (FSA) and Professor of Infectious Disease at the University of Birmingham.

Another excellent talk. I have missed learning and talking about science since I left school as none of my friends are interested in it. I appreciate the easy access to great speakers from Gresham.

[@aaronskoy957]

Get new friends.

[@fullnewsky]

Amazing talk. Love each and every one of these ❤

[@CuriousCyclist]

I love these lectures. Keep them coming. 👍

[@ozachar]

Amazing model proof of various key themes: (1) evolution can act/be very fast, in just a few generations. (2) behavior treats are genetic. And more....

[@johnbray3143]

can you get rid of the pulsing dot on the secondary screens?

[@WildBillCox13]

Fascinating stuff. Liked and shared.

[@bentationfunkiloglio]

I never fully appreciated how fascinating evolution is until I took the time to create some toy AI genetic algorithms. In particular, I was surprised by how sensitive evolution is to rates of mutations. A little bit goes a long way.

[@petersq5532]

use of antibiotics in husbandry has purely technical motivation. chicken and other livestock kept in such a crowed environment that foster and excelletates bacterial and fungal endemic.

[@brucethomas471]

Excellent talk. I am astonished that humans could ever be super small or tall, like dogs, if bred that way. But some young basketball players are 7 foot 5 inches or 2.25 meters! Some selection must be going on here, and one can wonder how far that will, or can, go.

[@MarcosElMalo2]

Species interaction guiding evolution goes back even further. Example: mitochondria.

[@annayosh]

Regarding the development of antibiotics, antibiotic resistance in a cruel way is worsening the economic aspect of this. Suppose a totally new antibiotic would be discovered or developed now, it would most probably be kept away so that we have something we can use against bacteria that are resistant to all 'normal' antibiotics.

[@ALavin-en1kr]

There is also the possibility that humans as humans started at the prototype and devolved. In that case there would be devolution, evolution, and involution to the prototype again. Dogs of course are a separate story.

[@a2sbestos768]

There's no such thing as devolution or involution, lol

[@charlesbrown1365]

By animal and plant domestication ; see first chapter of Darwin’s _Origin_.

[@sirbarringtonwomblembe4098]

No dogs are "dodgy"; but all are doggy!

[@sirbarringtonwomblembe4098]

But humans were produced by evolution. So isn't our influencing evolution a result of evolution generally? Whether it will ultimately be 'successful' is a moot point - nearly all species have died out.

Following "advice" of WYSIWYG re-evolution = reiteration Equilibrium in/of superimposed Quantum-fields Mechanism, relative-timing sync-duration nucleation Singularity-point @absolute zero-infinity reference-framing, aka Holographic Principle.., means humanity affects humanity as an adjunct to universal Eternity-now Entanglement Fusion-Fission Function Modulation Mechanism Lensing. Expertise in aspect-versions of observational empirical categories is advised, but as we're absolutely embedded in the process, the beginning-ending of Agnostic neutrality is unavoidably necessary to recreate the circumstances and choose Sciencing techniques and methods. Self Domestication is Universal, Neoteny information In-form-ation substantiation holography, logarithmic condensation quantization dimensionality, or wave-packaging of coherence-cohesion objectives vanishing-into-no-thing. Depending on Student Orientation.

@davidwilkie9551 Excellent synopsis of the lecture by ChatGPT.😮 😧👽

[@myparceltape1169]

How I chose my partner. For life. ❤

[@armyman3666]

Lol this is interfering with evolution not speeding it up

[@Horribilus]

He should stop directing the orchestra while he lectures. Terrible distraction.

[@myparceltape1169]

Close your eyes and listen till he tells you to look at the graph.
