Abstract in brief
The study discusses the fusion of two ancestral primate chromosomes that led to human chromosome 2, a key event in human evolution, with traditional estimates suggesting it occurred around 45 million years ago.
The researchers developed a new algorithm to analyze specific genetic markers (AT to GC substitutions) near the fusion site, estimating that this event actually took place approximately 0.9 million years ago, providing a more recent timeline.
Their approach not only refines the timing of the chromosome fusion but also offers a new method to understand evolutionary relationships among Great Apes, enhancing our knowledge of primate speciation.]
Human chromosome 2 resulted from the fusion of two ancestral chromosomes shared by chimpanzees, bonobos, and gorillas. An interesting new article suggests this fusion happened around 900,000 years ago (95% CI up to 1.5 million).

the end-to-end fusion of two ancestral chromosomes formed the human chromosome 2 (HSA2)..we estimate its formation time at 0.9 Mya with a 95% confidence interval of 0.4-1.5 Mya https://t.co/xDPc9LzkJ8
@SamiAntinniemi Ei ole ilmestynyt uutta kromosomia vaan kaksi kromosomia fuusioitui ehkä jopa 4.5 miljoonaa vuotta sitten.

Tot op de dag van vandaag wordt er aan dit fusieprobleem gerekend door bio-informatici. Wie deze chromosoomfusie botweg ontkent, blijft zitten met deze losse eindjes. En hij ziet de mens als een speciale creatie, zonder verband met de overige soorten. 4/n https://t.co/QuEe0q54hj

Barbara Poszewicka wykazała, że zdarzenie to miało miejsce jakieś 400 tysięcy do 1,5 miliona lat temu. Chociaż inni szacują, że około 4,5 miliona lat temu, to jej słowo jest póki co ostatnim w tej dyskusji.

This video explores key genetic developments, including chromosome 2 fusion and amino acid mutations, that differentiate humans from other animals. It highlights how specific genetic changes shaped human intelligence…
This study refines the timing of the human chromosome 2 fusion event, crucial in human evolution, estimating it occurred about 0.9 million years ago using genetic markers, offering new insights into primate evolution…
Darwin's theory has many limitations, making it less credible according to recent scientific research. The video explores these challenges and provides updated perspectives based on current scientific understanding.
@BrianRoemmele I read https://t.co/SHTGK6Qaax and https://t.co/emx1f4YTwN and they state a date of 400,000 to 1.5m years ago. It's interesting that the first date is close to the Jebel Irhoud discoveries.

@Allchina360ara1 @TecktonikDesMer @JackLeFouX Et on a trouvé effectivement dans les années 2000, qu'il y a 2 à 1.5 Ma, il y a eût un évenement de fusion sur le chromosome 2 rendant impossible tout hybridation entre les Panina et Hominina.

@marcado_razon @dan_cameron99 @iLoveTHICK78020 @NigelShortbread @GeorgeBatt34036 @TheSkeptic4122 And the source you provided really isn't great. For one they use Chromosome number in humans as evidence against common ancestry, where chimps have 48 and humans have 46. This is easily debunkable due to the fusion event of human chromosome 2

@ZenMaster333 @SandyChildOfGod Once again you're spouting the nonsense that there's no evidence yet you can't produce any for that claim.
One species "turning" into another, just check out what birds evolved from.
As to HSA2 fusion, where's the problem?

@CullenKehoe @Norse_Chieftain As for the common ancestor between the great apes and Homo sapiens (humans) genetics tells us that it was approximately 4.5 million years ago. https://t.co/04WtIVAUPi

@BorgerPieter @homosapiens300 @JongGerdien Denisovans zijn geen neanderthalers, maar er nauw aan verwant. De fusie heeft plaatsgevonden voor beide groepen ontstonden: https://t.co/A3ipG3seqv.
En waarom zou 2x23 chromosomen hét criterium zijn?
@doofgeek4011 That fusion event was about 4-4.5 million years ago. This bottleneck is less than 1 million, so that ship had already sailed. ;)
https://t.co/Hz5yvSTdHa
@richcollins @paulg And I doubt that this 1k group was the only one to survive from the original 100k-strong population. So why didn't they interbreed at some later point after their 100k year-long isolation? Makes me think that chr2 fusion was a speciation event.

If you're wondering what on Earth happened to produce our human chromosome 2, it's the result of a fusion of two chromosomes. It may have happened less than a million years ago according to this recent study. https://link.springer.com/article/10.1186/s12864-022-08828-7
Human chromosome 2 resulted from the fusion of two ancestral chromosomes shared by chimpanzees, bonobos, and gorillas. An interesting new article suggests this fusion happened around 900,000 years ago (95% CI up to 1.5 million).
