Recreating evolution and the jump from single cells to multicellularity. A recent experiment has created evidence of evolution by creating multi-celled life that shows evidence of circulation, life cycles and division of labor. Have they revealed secrets that nature has been keeping for millions of years...

In recent decades, the boundary between a colony of unicellular and a single multicellular organism has gotten fuzzier and fuzzier. Biofilms, sponges, ...

I was confused what was up with this video, because my class did a similar lab in high school around 2013. Then I did some googling and figured out that the lab we did was designed by Dr. Ratcliff, and our class was one of the first to try it. It was kind of amazing getting to do actual biology when I was only 15, though I remember the frustration of not always getting the results we were hoping to get through the lab.

It won't convince anyone who actually needs to be convinced, the rest of us are already on board.

I love your channel. I showed my mom your 3 points of evolution but only played the sound AFTER you used the word evolution so she wouldn't hear that word evolution. As we went on she agreed with all 3 points. I then backed it up to start where you say it is evolution and she couldn't believe it. Half the ppl who disagree with evolution don't even know what they disagree with! Thanks for helping plant that seed that might grow to a little skepticism

Cells clustering together have an advantage in buffering against the environment, bacteria particularly likes to screte biofilms.
-
Wow and in such a short amount of time..
wonder what would happen if we did this for 100 years, or 6.5 billion? -
As someone who studied evolutionary microbiology this was one of my professor’s biggest qualms that led him to believe in determinism. Very interesting! Thanks!!

.. and then they were left to themselves over the weekend. The following Monday the scientist were a bit puzzled to see that the yeast had opened bank accounts, started investing and were off to buy a new Audi.

So multicellularity came before oxygenation? That's pushing things way back into deeper time!
-
This is truly fascinating! Thank you for making this video.
-
Honestly; I hate in-video-ads, but this was done with such grace and perfection that you even got me hooked enough to go visit the website. 10/10

Next they should give oxygen back, and at the same time increase the danger of being small with actual predators, make them suffer so we can get better things
-
What I really wanna know is where those yeast are gonna be in ten years
-
This is the coolest discovery I’ve seen in a longtime

As a person who was raised in religious dogma, I have struggled all my life attempting to understand creation. Evolution IMO is undeniable and if there is/was a God that entity set into motion the building blocks of life and over billions of years we are the result? What I can't wrap my mind around is what started the event or the "Big Bang." Do we have a soul as each individual has a personality, and where does that go after death...
-
i really hope they continue to work with these, to continue the evolution. maybe give it a stronger pressure to evolve a circulatory system, or stronger pressure to move, or whatever

Although this research is interesting, it needs to be interpreted carefully. Unicellular does not always mean primitive. Far from being the "simple" organisms many people (including some biochemists who should know better) imagine them to be, yeasts are part of a huge group of complex fungi and appear to have become unicellular by evolving from ancient filamentous species. Therefore this experiment could simply be reactivating dormant ancestral genes, roughly analogous to breeding humans with larger appendixes or fur. It is at best a crude model for how multicellularity arose in the first place.

Why do humans eschew movement and instead interact with the world via its various delivery systems?
Outside conditions are getting tougher - crowds, traffic jams, pollution, harsh weather, crime, repressive laws, etc. Meanwhile, homes are becoming ever better serviced. There comes a point where the couch looks more inviting than the car or walking shoes. The ability to move will become less useful than being part of a larger group - because the group is extra good at accessing and processing stuff.

It's amazing that people still deny evolution when anyone can evolve their own species with a little time and patience.

Absolutely fascinating research.
