evolucija

A model of a skull discovered on a remote Indonesian island is held by an employee at the Science Museum in London October 27, 2004. Australian scientists have found a new species of hobbit-sized humans that lived about 18,000 years ago on a remote island in a discovery that adds another piece to the complex puzzle of human evolution. The partial skeleton of Homo floresiensis, found in a cave on the island of Flores, is of an adult female that was just a metre (3 feet) tall, had a chimpanzee-sized brain and was substantially different from modern humans.

EXCLUSIVE: Story from Jam Press (Sleep Liver Problems)Pictured: A social media user reacts to Dr Greg Mongeon's health warning sign.VIDEO: Doctor warns anyone who can't sleep between 2am and 4am may have THIS problemA doctor has gone viral after warning anyone who regularly fails to sleep between 2am and 4am that they may have liver problems – because their "pathways are jammed'.Dr Greg Mongeon, who has 248,000 followers, cautioned that wakefulness at this time could be a symptom of underlying health issues.He explained that each organ has an "alert time" – and usually finding yourself awake during these particular hours of the night might be a big red flag.His revelation left viewers stunned with the video racking up over 278,000 views."Restless sleep is a common symptom people present with," the 48-year-old from Lakeville, Minnesota in the US told What's The Jam."[That might be] waking up early and not being able to fall asleep or not falling asleep easily."In traditional Chinese medicine they talk about each organ having an 'awake' or 'alert' time."And the liver is 2am to 4am."So if you wake up at that time consistently, it's a sign that your body is saying, 'help'."It may be a sign of poor drainage systems, especially the liver and gut."These poor drainage systems are easily tested through laboratory markers."But normal ranges do not indicate optimal [organ] function."The clip, posted three weeks ago, has gone viral with the doctor's fans shocked by the news – with many admitting this exact thing happens to them.Others asked for advice.Angelica said: "I do wake up between that time. But just to pee. Then I fall asleep without a problem. Is that still a problem?"Doctor Greg replied to the question, saying: "If it makes sense to you that you drank a lot of fluid prior to bed, but in many cases, it can indicate your stress hormones are turning on a little too early which is often tied to blood sugar and liver signaling."Athanasia added:.11 Feb 2026Pictured: Story from Jam Press (Sleep Liver Problems)Pictured: Stock image of a woman in bed.VIDEO: Doctor warns anyone who can't sleep between 2am and 4am may have THIS problemA doctor has gone viral after warning anyone who regularly fails to sleep between 2am and 4am that they may have liver problems – because their "pathways are jammed'.Dr Greg Mongeon, who has 248,000 followers, cautioned that wakefulness at this time could be a symptom of underlying health issues.He explained that each organ has an "alert time" – and usually finding yourself awake during these particular hours of the night might be a big red flag.His revelation left viewers stunned with the video racking up over 278,000 views."Restless sleep is a common symptom people present with," the 48-year-old from Lakeville, Minnesota in the US told What's The Jam."[That might be] waking up early and not being able to fall asleep or not falling asleep easily."In traditional Chinese medicine they talk about each orga.,Image: 1074036630, License: Rights-managed, Restrictions: NO Australia, Germany, Norway, South Korea, Sweden, United Kingdom, United States, Unknown Country, Model Release: no

**VIDEO AVAILABLE: CONTACT INFO@COVERMG.COM TO RECEIVE**BY MARK WORGANOctopuses have a special 'sex arm' they use to identify partners by taste and mate with them, according to researchers at Harvard University.The findings, published in the journal Science, show that males can locate and fertilise females without seeing them, sometimes mating at arm's length.Scientists say the research sheds new light on how these largely solitary animals reproduce, and may help explain how new species evolve.Male octopuses have eight arms, but one - known as the hectocotylus - is specially adapted for reproduction."Male octopuses use a specialized arm called the hectocotylus to identify females and navigate their internal organs to reach the oviduct and deliver sperm," the researchers, led by lead author Pablo Villar, write in their paper.During mating, the arm searches for the female's mantle cavity and deposits packets of sperm, known as spermatophores. The researchers found that the arm is lined with receptors similar to those used by other arms to explore the seabed.Octopus limbs are highly sensitive, with each suction cup containing thousands of sensory cells. Much of the animal's nervous system is distributed throughout its arms, allowing them to act independently of the brain.To test how the animals use these abilities, scientists observed mating behaviour in the California two-spot octopus (Octopus bimaculoides).Males and females were placed on opposite sides of a tank, separated by a barrier with small openings. Despite being unable to see each other, males were able to extend their specialised arm through the divider, locate the female and begin mating.The study found that such interactions could take place even in complete darkness. When two males were paired, however, no mating attempts were observed, suggesting females emit a specific chemical signal.Further experiments pointed to the hormone progesterone as a key factor.Research
