You May Have Helped Contribute to This Scientific Study

Any normal person with a smartphone would take a picture of an aurora and post it on social media, which is what led Elizabeth MacDonald and Nathan Case to found the Aurorasaurus website. Since scientists can't be everywhere at all times to spot these auroras, they rely on social media to do it for them.


If you've ever tweeted a photo of an aurora, you may have helped contribute to this scientific study.

Auroras are beautiful features of geomagnetic storms, but these storms can cause damage to human systems resulting in power outages and knocking out satellites. One in 1989 melted transformers, causing the lights to go out in Quebec, leaving 6 million people in the dark.

Dr. Michio Kaku, a theoretical physicist, talks about the kind of devastation we could expect from an event larger than the one in 1989 — one akin to the Carrington Event, which occurred in 1859.

These storms are caused by disruptions in the Earth's magnetosphere from solar wind. So, the ability to forecast these events is important to maintaining our communication systems. In order to do this scientists need data to track where and when they appear.

Any normal person with a smartphone would take a picture of an aurora and post it on social media. This universal truth in this internet age led Elizabeth MacDonald and Nathan Case to found the Aurorasaurus website. Since scientists can't be everywhere at all times to spot these auroras, they rely us to be the data collectors

The two credited the citizens of the internet in their recent study.

"Without the citizen science observations, Aurorasaurus wouldn't have been able to improve our models of where people can see the aurora," said Case, a senior research associate at Lancaster University, United Kingdom. "The team is very thankful for our community's dedication and are excited to have more people sign up."

Social media platforms have allowed us to expand our fabric of knowledge and to become the interns of great scientists. Through it researchers MacDonald and Case were able to study recordings by citizen scientists “during March and April 2015 using the Aurorasaurus platform and cover one large geomagnetic storm and several smaller events.”

“The short term vision for Aurorasaurus is to become an interactive hub for aurora enthusiasts at the intersection of citizens and science,” said MacDonald, a researcher at NASA’s Goddard Space Flight Center. “Long term, this engaged community can be sustained and evolve together — and the tools can be expanded to be useful in other disciplines within our technological society.”

The internet has allowed us to connect to one another and share knowledge in such a way that it's changing the field of science. Science is no long a field for the educated and elite, we can all observe and report to help further our studies of this world and others.

New fossils suggest human ancestors evolved in Europe, not Africa

Experts argue the jaws of an ancient European ape reveal a key human ancestor.

Surprising Science
  • The jaw bones of an 8-million-year-old ape were discovered at Nikiti, Greece, in the '90s.
  • Researchers speculate it could be a previously unknown species and one of humanity's earliest evolutionary ancestors.
  • These fossils may change how we view the evolution of our species.

Homo sapiens have been on earth for 200,000 years — give or take a few ten-thousand-year stretches. Much of that time is shrouded in the fog of prehistory. What we do know has been pieced together by deciphering the fossil record through the principles of evolutionary theory. Yet new discoveries contain the potential to refashion that knowledge and lead scientists to new, previously unconsidered conclusions.

A set of 8-million-year-old teeth may have done just that. Researchers recently inspected the upper and lower jaw of an ancient European ape. Their conclusions suggest that humanity's forebearers may have arisen in Europe before migrating to Africa, potentially upending a scientific consensus that has stood since Darwin's day.

Rethinking humanity's origin story

As reported in New Scientist, the 8- to 9-million-year-old hominin jaw bones were found at Nikiti, northern Greece, in the '90s. Scientists originally pegged the chompers as belonging to a member of Ouranopithecus, an genus of extinct Eurasian ape.

David Begun, an anthropologist at the University of Toronto, and his team recently reexamined the jaw bones. They argue that the original identification was incorrect. Based on the fossil's hominin-like canines and premolar roots, they identify that the ape belongs to a previously unknown proto-hominin.

The researchers hypothesize that these proto-hominins were the evolutionary ancestors of another European great ape Graecopithecus, which the same team tentatively identified as an early hominin in 2017. Graecopithecus lived in south-east Europe 7.2 million years ago. If the premise is correct, these hominins would have migrated to Africa 7 million years ago, after undergoing much of their evolutionary development in Europe.

Begun points out that south-east Europe was once occupied by the ancestors of animals like the giraffe and rhino, too. "It's widely agreed that this was the found fauna of most of what we see in Africa today," he told New Scientists. "If the antelopes and giraffes could get into Africa 7 million years ago, why not the apes?"

He recently outlined this idea at a conference of the American Association of Physical Anthropologists.

It's worth noting that Begun has made similar hypotheses before. Writing for the Journal of Human Evolution in 2002, Begun and Elmar Heizmann of the Natural history Museum of Stuttgart discussed a great ape fossil found in Germany that they argued could be the ancestor (broadly speaking) of all living great apes and humans.

"Found in Germany 20 years ago, this specimen is about 16.5 million years old, some 1.5 million years older than similar species from East Africa," Begun said in a statement then. "It suggests that the great ape and human lineage first appeared in Eurasia and not Africa."

Migrating out of Africa

In the Descent of Man, Charles Darwin proposed that hominins descended out of Africa. Considering the relatively few fossils available at the time, it is a testament to Darwin's astuteness that his hypothesis remains the leading theory.

Since Darwin's time, we have unearthed many more fossils and discovered new evidence in genetics. As such, our African-origin story has undergone many updates and revisions since 1871. Today, it has splintered into two theories: the "out of Africa" theory and the "multi-regional" theory.

The out of Africa theory suggests that the cradle of all humanity was Africa. Homo sapiens evolved exclusively and recently on that continent. At some point in prehistory, our ancestors migrated from Africa to Eurasia and replaced other subspecies of the genus Homo, such as Neanderthals. This is the dominant theory among scientists, and current evidence seems to support it best — though, say that in some circles and be prepared for a late-night debate that goes well past last call.

The multi-regional theory suggests that humans evolved in parallel across various regions. According to this model, the hominins Homo erectus left Africa to settle across Eurasia and (maybe) Australia. These disparate populations eventually evolved into modern humans thanks to a helping dollop of gene flow.

Of course, there are the broad strokes of very nuanced models, and we're leaving a lot of discussion out. There is, for example, a debate as to whether African Homo erectus fossils should be considered alongside Asian ones or should be labeled as a different subspecies, Homo ergaster.

Proponents of the out-of-Africa model aren't sure whether non-African humans descended from a single migration out of Africa or at least two major waves of migration followed by a lot of interbreeding.

Did we head east or south of Eden?

Not all anthropologists agree with Begun and his team's conclusions. As noted by New Scientist, it is possible that the Nikiti ape is not related to hominins at all. It may have evolved similar features independently, developing teeth to eat similar foods or chew in a similar manner as early hominins.

Ultimately, Nikiti ape alone doesn't offer enough evidence to upend the out of Africa model, which is supported by a more robust fossil record and DNA evidence. But additional evidence may be uncovered to lend further credence to Begun's hypothesis or lead us to yet unconsidered ideas about humanity's evolution.
