the foot bone connected to the knee bone...
...the knee bone connected to the skull bone,
the hand bone connected to the jaw bone
and that's how we won the fight.
A team of archeologists has pieced together bone fragments to reveal what is, apparently, a new species of human. The discovery of a foot bone lodged in the Callao Cave, a limestone grotto on the island of Luzon in the Philippines, gave the researchers, led by the University of Philippines and the National Museum of Natural …
And the subtitle says 'in a Filopino cave.' It's technically not grammar, but still it certainly ain't right.
ETA: It's not helping that it's not clear just which correction OC meant to make there, or even whether he's saying 'Filipino' is the wrong version or the correct one. I'm assuming it's the correction.
" lived on the island 700.000 years ago' or " started populating the islands 67.000 years ago"
These bones are 67k years old; other finds point to humanoids living on the islands 700k years back, but those might not have been the same species as no direct evidence to that effect has (yet) been found.
This, along with the hobbits intrigues me. I saw reports saying this must have meant sea faring primitives given these have been islands for a looong time, and the out-of-Africa hypothesis for Homo-X evolution. Or there was some parallel evolution, or our understanding of our geological history is incorrect. Or perhaps the classification of these bones is incorrect.
"Islands" are fun for evolution quirkiness
Read up about it (insular dwarfism & insular gigantism)
It is common for island creatures to evolve to a different size be ii considerably larger or smaller than their mainland counterparts
.. For "island" you can interpret it as any smallish restricted habitat e.g. get similar stuff in areas "cut off" by high mountains etc.
"Having watched studies of human evolution develop over a number of years it seems very likely that proposed evolutionary trees will get revised. Or refined according to choice of words."
Likely, because even NOW scientists are fudging things as they go. For example: one of the tenants of classifications, the definition of species: "
From the dictionary:
"a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding."
From UC Berkeley:" A species is often defined as a group of individuals that actually or potentially interbreed in nature."
From Wikipedia: " A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction."
And yet, with these CLEAR definitions of species, we still see homo sapiens, homo neanderthals, and homo denisova spoken/written/researched about as different species, when it is clear that they (all three) interbred very successfully for thousands of years. They are different subspecies of a singlet species. When I put this question to a conference of biologists, NONE could give even one explanation as to why we still refer to them as different species when these three populations could so clearly interbreed and produce fertile offspring.
I think biologists dont know what to do!
Look at the wiki page for homo denesova: "The Denisovans or Denisova hominins ( /dɪˈniːsəvə/ di-NEE-sə-və) are an extinct species or subspecies of archaic humans in the genus Homo."
Um-- NO!. They interbred with neanderthals and modern humans... successfully. the are NOT an extinct species. Further, as a DISTINCT subspecies, Denesova and Nearnderthal are extinct. As a DISTINCT subspecies, modern man exists only in some places in Africa, and it is almost certain that the homo sapiens subspecies will go extinct. All three should be classified as a subspecies of "homo neandersapiendenisova"
And yet.... it hasn't happened.
I still think it's fascinating. And a rich source of puns. So Pleistocene, morphology, and an escape from Sundaland..
But fun trying to extrapolate based on limited data, ie a few bones and other remains. Plus the island dwarfism potentially causing it's own evolutionary drift in various branches of the Homo- family tree. I also think it's great that a generation ago, much of this stuff would only be really known amongst interested anthropologists, and now thanks to the magic of the Internet, we can learn and share so much knowledge.
I've also often wondered what triggered evolution, and how flexible the branches were in the early days, ie the interbreeding, and presumably a combination of genetics and competition leading to the dominance of Homo Sapiens rather than Neanderthals, which to me seemed to have some potential advantages.
The article says 'not fully grown' so inferring fully grown size sounds a bit like Time Team archeology - "Here's a single post hole. From this we can determine that it was a fully thatched, four fur semi with en-suite sacrifice facility, large mammoth preparation area and outside screened toilet hole with hot and cold running stream".
I had a girlfriend like that once. Well, apart from the actual killing and bringing home a rhinoceros as that's generally frowned upon in polite society nowadays, never mind running afoul of laws protecting endangered species.
But if one had dared to look at her the wrong way ...
Every time they dig up some bones belonging to a previously unknown humanoid species it always reminds me of the time, a very long time ago, I read HP Blavatsky's books 'The secret Doctrine', concerning the root races and sub races from now long lost continents. Written in 1888.
The Japanese outpost of Indian services giant Tata Consultancy Services has revealed it is working on the "Internet of Actions" – an effort to bring the sense of touch to the internet.
Tata has paired with a Japanese upstart from Keio University, Motion Lib, to spearhead the endeavor.
TCS said it will eventually deliver a "new social infrastructure" by commercializing Motion Lib tech. But first and more practically, the company will create a demonstration environment for "real haptics" technology at its Digital Continuity Experience Center (DCEC) showroom.
A piece of Soviet-era physics equipment may be the key to worldwide geothermal energy.
Sadly for NASA's mission to take samples from the asteroid Psyche, software problems mean the spacecraft is going to miss its 2022 launch window.
The US space agency made the announcement on Friday: "Due to the late delivery of the spacecraft's flight software and testing equipment, NASA does not have sufficient time to complete the testing needed ahead of its remaining launch period this year, which ends on October 11."
While it appears the software and testbeds are now working, there just isn't enough time to get everything done before a SpaceX Falcon Heavy sends the spacecraft to study a metallic-rich asteroid of the same name.
NASA is finally ready to launch its unmanned Orion spacecraft and put it in the orbit of the Moon. Lift-off from Earth is now expected in late August using a Space Launch System (SLS) rocket.
This launch, a mission dubbed Artemis I, will be a vital stage in the Artemis series, which has the long-term goal of ferrying humans to the lunar surface using Orion capsules and SLS technology.
Earlier this week NASA held a wet dress rehearsal (WDR) for the SLS vehicle – fueling it and getting within 10 seconds of launch. The test uncovered 13 problems, including a hydrogen fuel leak in the main booster, though NASA has declared that everything's fine for a launch next month.
Engineers at the University of Pennsylvania say they've developed a photonic deep neural network processor capable of analyzing billions of images every second with high accuracy using the power of light.
It might sound like science fiction or some optical engineer's fever dream, but that's exactly what researchers at the American university's School of Engineering and Applied Sciences claim to have done in an article published in the journal Nature earlier this month.
The standalone light-driven chip – this isn't another PCIe accelerator or coprocessor – handles data by simulating brain neurons that have been trained to recognize specific patterns. This is useful for a variety of applications including object detection, facial recognition, and audio transcription to name just a few.
Video Robot boffins have revealed they've created a half-millimeter wide remote-controlled walking robot that resembles a crab, and hope it will one day perform tasks in tiny crevices.
In a paper published in the journal Science Robotics , the boffins said they had in mind applications like minimally invasive surgery or manipulation of cells or tissue in biological research.
With a round tick-like body and 10 protruding legs, the smaller-than-a-flea robot crab can bend, twist, crawl, walk, turn and even jump. The machines can move at an average speed of half their body length per second - a huge challenge at such a small scale, said the boffins.
Updated Intel and QuTech claim to have created the first silicon qubits for quantum logic gates to be made using the same manufacturing facilities that Intel employs to mass produce its processor chips.
The demonstration is described by the pair as a crucial step towards scaling to the thousands of qubits that are required for practical quantum computation.
According to Intel, its engineers working with scientists from QuTech have successfully created the first silicon qubits at scale at Intel's D1 manufacturing factory in Hillsboro, Oregon, using a 300mm wafer similar to those the company uses to mass produce processor chips.
The largest academic supercomputer in the world has a busy year ahead of it, with researchers from 45 institutions across 22 states being awarded time for its coming operational run.
Frontera, which resides at the University of Texas at Austin's Texas Advanced Computing Center (TACC), said it has allocated time for 58 experiments through its Large Resource Allocation Committee (LRAC), which handles the largest proposals. To qualify for an LRAC grant, proposals must be able to justify effective use of a minimum of 250,000 node hours and show that they wouldn't be able to do the research otherwise.
Two additional grant types are available for smaller projects as well, but LRAC projects utilize the majority of Frontera's nodes: An estimated 83% of Frontera's 2022-23 workload will be LRAC projects.
Researchers at the Paul Scherrer Institute and ETH Zurich in Switzerland have managed to accomplish a technological breakthrough that could lead to new forms of low-energy supercomputing.
It's based around something called artificial spin ice: think of water molecules freezing into a crystalline lattice of ice, and then replace the water with nanoscale magnets. The key to building a good spin ice is getting the magnetic particles so small that they can only be polarized, or "spun," by dropping them below a certain temperature.
When those magnets are frozen, they align into a lattice shape, just like water ice, but with the added potential of being rearranged into a near infinity of magnetic combinations. Here the use cases begin to emerge, and a couple breakthroughs from this experiment could move us in the right direction.
British outfit First Light Fusion claims it has achieved nuclear fusion with an approach that could provide cheap, clean power.
Rather than rely on expensive lasers, complicated optical gear, and magnetic fields, as some fusion reactor designs do, First Light's equipment instead shoots a tungsten projectile out of a gas-powered gun at a target dropped into a chamber.
We're told that, in a fully working reactor, this high-speed projectile will hit the moving target, which contains a small deuterium fuel capsule that implodes in the impact. This rapid implosion causes the fuel's atoms to fuse, which releases a pulse of energy.
