Scientists are conducting a long-term experiment on evolution in the lab, to investigate how single-celled organisms could evolve into multicellular lifeforms. After thousands of generations, their yeast grew 20,000 times bigger and 10,000 times tougher.
The idea of an evolutionary “missing link” usually conjures images of a hairy ape-like hominid, but there are actually much more profound missing links in the chain. One of the biggest gaps sits between single-celled and multicellular organisms, which marks a key step in the development of complex life on Earth.
Now, scientists from Georgia Tech have reported the first results of an experiment that they hope to continue running for decades, with a pretty lofty goal – evolving single-celled lifeforms into brand new multicellular lifeforms. Directed evolution experiments have been conducted for decades, even winning the Nobel Prize for Chemistry in 2018, but those are usually focused on making new drugs or solving other problems, not plugging holes in our distant family tree.
In this first phase of this Multicellularity Long-Term Evolution Experiment (MuLTEE), the researchers started with a species called snowflake yeast. The microbes were grown in shaking incubators, and every day the team would engage in a spot of artificial natural selection – colonies that had grown the fastest and reached the biggest sizes were selected for further cultivation. Repeat this process thousands of times over, and you’ve got a pretty good approximation of the environmental forces that favor certain characteristics in natural evolution.
And sure enough, after about 3,000 generations, the yeast had evolved to form clusters of more than 500,000 cells – more than 20,000 times larger than the original strain. In the process they’d become visible to the naked eye, and had become around 10,000 times tougher, on par with wood.

I guess you posted the Genesis text to make a case for short creation days (six 24-hour days). That's possible. It's also possible they were six long eras.
Let's look at Genesis 1:23's "And there was evening, and there was morning—the fifth day." The word "evening" in the Hebrew is "‘ereb", which has multiple literal meanings. One of those is evening, and one of those is beginning. The same with the word "morning" original Hebrew word "boqer" meaning morning, or ending, or other literal definitions. And the word "day" in Hebrew is "yôm" and can mean daytime, a 24-hour day, or era of unspecified length. (Think of your grandpa saying, "back in my day".) Repeat that for the other 5 creation days (not counting the 7th day).
Basically, the Genesis 1 text alone give neither old earth creationists nor young earth creationists a leg to stand on in making our cases for the age of the earth or how long each of God's creation "days" lasted. (Think esegis reading, not exeges reading.) Of interesting note, the 7th day in Genesis 2:2 has no evening and morning to note a beginning and end of the 7th "day". This to me suggests (but doesn't imply) that the 7th "day" itself hasn't ended (at least not by Moses' time), suggesting that the 7th yôm is to be translated as era of rest instead of day of rest. Perhaps the other 6 creation yôm's are eras too.
So IMHO us Christians have no dog in the fight on the age of the earth or the length of the creation "days". Our faith in the Bible's creation story isn't shaken no matter what archaeology shows us about the age of the earth. However, the atheists faith in natural selection is shaken when the record of nature doesn't show a gradual speciation across billions of years like their belief demands. The record of nature IMHO shows God's miraculous hand brought forth new species of organisms in various bursts that natural selection can't explain, and even appearing in the fossil record in the same order listed in Genesis (plants, fish and birds, land animals, human beings).
Exactly!

It’s not even micro evolution. They started with yeast and ended up with yeast.
“ Yet, a cluster is still not a multi-cellular organism. So their experiment was a failure. They’re just spinning it to keep the grant money flowing”

Yep. Nothing new here. Perhaps they’re surprised that if you repeatedly select for a characteristic trait in a stock over hundreds of generations you’ll get that trait in your stock.
Yet another mark of our current society… we’re plagued by scientists with no creativity or imagination.
Most mutations involve death to the organism.
2 Peter 3:8
But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.
“... the atheists faith in natural selection is shaken when the record of nature doesn’t show a gradual speciation across billions of years like their belief demands.”
There is no Half-Giraffe......................😉
Good to see someone rise to the occasion.......................
It was better to that than to loaf all day.
I can’t believe they created a ‘super yeast’ whose sole reason for existence is to produce that EVIL CARBON DIOXIDE GLOBAL WARMING GREENHOUSE GAS THAT WILL KILL US ALL IN TEN YEARS!................Or less, as YMMV.............
Just imagine how much *jam* will have to be produced to eat all that bread... mmmmm...
Beware the Blob.😱
Exactly right.
