The Teeth of Known Ancestors Was Found By A Student In Dorset
The fossil remains of two rat-like creatures believed to be our oldest known ancestors have been discovered.
The two teeth, from two different species, were found
in samples of Cretaceous period rock from cliffs in Swanage, Dorset by
student Grant Smith.
The animals - who lived 145 million years ago in the shadows of
the dinosaurs - are believed to be ancestors of most mammals living
today, including the blue whale, the pygmy shrew and humans.
Dr
Steven Sweetman, of the University of Portsmouth, said his "jaw
dropped", when Mr Smith brought him the specimen to have a look at.
He
said: "The teeth are of a type so highly evolved that I realised
straight away I was looking at remains of Early Cretaceous mammals that
more closely resembled those that lived during the latest Cretaceous,
some 60 million years later in geological history.
"In the world
of palaeontology there has been a lot of debate around a specimen found
in China, which is approximately 160 million years old. This was
originally said to be of the same type as ours but recent studies have
ruled this out.
"That being the case, our 145 million-year-old
teeth are undoubtedly the earliest yet known from the line of mammals
that lead to our own species."
iPhone X Has Already Hit The Market Therefore Profit is Boosting For Apple
The tech giant forecast fiscal first-quarter revenue of
$84bn-$87bn, putting it within striking distance of becoming the first
trillion dollar public company.
Apple shares rose 4% in after-hours trading to hit an all-time high on the back of the announcement.
But Apple executives shrugged off those fears, with chief financial
officer Luca Maestri saying they were "quite happy" with how
manufacturing of the iPhone X was progressing.
Apple's market capitalisation of around $868bn already makes it the world's most valuable publicly-traded company.
The company's net income rose to $10.71bn, or $2.07 per share.
A Mysterious Empty Space(Void) Has Been Discovered in The Great Pyramid of Egypt
It is one of three pyramids at the Giza complex on the
outskirts of Cairo and is the only one of the Seven Wonders of the
Ancient World that remains standing.
Using a technique called muography, researchers have been analysing changes in the density of the rock inside the pyramid.
Constructed more than 4,500 years ago, the pyramid is believed to
have been built as a tomb for the pharaoh Khufu, also known as Cheops.
It is one of three pyramids at the Giza complex on the
outskirts of Cairo and is the only one of the Seven Wonders of the
Ancient World that remains standing.
Using a technique called muography, researchers have been analysing changes in the density of the rock inside the pyramid.
The
cavity above the pyramid's Grand Gallery, which was discovered by
Japanese and French scientists and has been described as a
"breakthrough", is not obviously accessible and it is not known whether
it holds anything of value.
It is approximately 30m long and several metres in height, but the researchers are not describing it as a chamber.
Social Media App (Whatapp) Has Been Hit by 'Worldwide Outrage'
Due to an unknown issue affecting the smartphone app, users were seeing the clock symbol after attempting to send a message, meaning that the message hadn't been sent to WhatsApp's servers.
The website for the messaging app also appeared to be down in what may be a domino effect.
The outage may be an embarrassment for WhatsApp's parent, Facebook, which has this week announced record revenues from advertising.WhatsApp did not give Sky News a statement regarding the cause of the incident, which lasted close to an hour.
A company spokesperson said: "Earlier today, WhatsApp users globally had trouble accessing the app for about an hour. This issue has been fixed and we apologise for the inconvenience."
They added: "This was not the result of a cyberattack."
