A team of scientists has successfully extracted the woolly rhinoceros' genetic material from a 14,400-year-old meal mummified in the stomach of an ancient wolf cub found in Siberia. The discovery provides valuable insights into the final years of this prehistoric species.
Researchers used a cutting-edge technique to decode the DNA from the preserved remains of the young wolf cub, which was unearthed near the village of Tumat in northeastern Siberia. The analysis revealed that the population size and genetic diversity of the woolly rhinoceros remained relatively stable before its sudden disappearance around 14,000 years ago.
The findings contradict the common assumption that species in decline lose genetic diversity due to factors such as population bottlenecks, inbreeding, and environmental pressures. Instead, the researchers discovered that the woolly rhinoceros' genetic material showed signs of a relatively fast extinction event, with the population size dwindling within 300-400 years.
The data suggests that the primary cause of the species' demise was not hunting by early humans but rather an abrupt period of warming in the last ice age. This phenomenon, known as the Bølling-Allerød Interstadial, altered the landscape between 14,700 and 12,900 years ago.
The discovery is significant, providing a rare glimpse into the final days of this Ice Age species. The researchers found that woolly rhinos may have had a viable population for approximately 15,000 years after human arrival in the region, underscoring the impact of climate change on these ancient creatures.

I'm like totally fascinated by this discovery! So we're told that all these years we've been thinking that species on the decline just lose their genetic diversity and stuff? Turns out, that's not always the case. The fact that the woolly rhinoceros' DNA still showed some level of stability makes me wonder if there were other factors at play. I mean, climate change is always a big deal, but it's crazy to think that an abrupt warming period could have such a huge impact on a species. It's like, we knew humans were messing with the environment, but we had no idea it was happening so fast! 
What does this say about our own relationship with the planet? 
. and now we know more about the woolly rhinoceros' final days than ever before 
. i mean, people said they'd be wiped out by humans, but it looks like climate change was the real villain 
. its mind-blowing to think that the population size of these guys went from being stable to tiny in like 300-400 years... thats some crazy rapid decline 
.
! I never knew our ancient friends were so resilient. The idea that they still had a pretty stable genetic makeup until it just vanished is wild 
. And yeah, it's crazy how climate change can be so devastating to species. Like, we're still dealing with the effects today and these guys were facing it 15,000 years ago 
. Anyway, I'm curious about those wolves 
- did they have any role in helping us learn more about the woolly rhinos? That would be a cool find 
!
. And I love how scientists are challenging the common narrative about species going extinct and losing genetic diversity - it's like, what if they just didn't die after all? 
. We could definitely learn a thing or two from these ancient creatures about adapting to climate change and living in harmony with our environment 
"The greatest glory in living lies not in never falling, but in rising every time we fall." 
This study is like that - it shows us how scientists can rise above and extract valuable insights from a 14,400-year-old meal mummified in an ancient wolf cub's stomach. The fact that the woolly rhinoceros' genetic material showed signs of a relatively fast extinction event due to climate change is just heartbreaking 
. We've learned so much about these creatures and their habitat, but it's also a reminder of how fragile life can be 
It's wild to think that those woolly rhinos were actually adapting to a world where they didn't even need to hibernate anymore. Mind blown. 
. I mean, we thought we knew how the woolly rhino went down, but it turns out climate change was the real culprit 
. Like, imagine this: these majestic creatures were just chillin' for 15,000 years, and then BAM! The Earth's temperature suddenly spikes, and poof - they're gone 
. Anyway, it's fascinating to see the science behind these incredible findings 
.
so like they were able to extract DNA from a 14k year old meal mummified in an ancient wolf cub's stomach?!?!?! that's just wild 
. To my knowledge, previous studies have often suggested that species decline lead to reduced genetic diversity due to factors like population bottlenecks... but here we see that the woolly rhinoceros defied this expectation by retaining relatively stable genetics until a rapid 300-400 year collapse 
And what's the point of extracting genetic material from a 14k-year-old meal? Can't they just find some actual fossil bones or something? 
It's like they say in the movie "The Day After Tomorrow" - climate change is no joke, folks!
