Chickens are said to be the closest living relatives of the Tyrannosaurus rex. Ever since the finding was reported, the humble chicken has been put through several experiments. Once researchers from the University of Chicago and University of Chile attached fake dino tails made of wood and clay to chickens to see how the bipedal carnivore T. rex would have walked.

The analysis of DNA was done to the fossil of dinosaur also known as T-Rex which was found in 2003. The fossil itself was unique, because it contained a little bit of soft tissues like blood vessel, which allow the researchers to extract sufficient amount of DNA for the research.

The scientists were also comparing the DNA of a Mastodon fossil to modern days animals and the result was amazing. They found that the proteins found in the T-Rex fossil were most similar to those of chickens, and the mastodon were most similar to modern day elephants.

For a long time, actually scientists have predicted the correlation between birds and dinosaurs based on the shape of their bones. But that was all just a prediction without any further researches. And the research conducted in 2008 gave the real answer.

“We determined that T rex, in fact, grouped with birds – ostrich and chicken – better than any other organism that we studied,” said Prof John Asara from Harvard to Telegraph. It determined avians’ relationships with non-avian dinosaur’s evolution.

“We also show that it groups better with birds than modern reptiles, such as alligators and green anole lizards,” he continued. It means that although dinosaurs were reptiles, modern days reptiles are their more distant cousins rather than birds.

Yes, we all know that dinosaurs met the extinction when a giant asteroid hit the earth, but actually not all of those dinosaurs died out. But actually, some dinosaurs with smaller size didn’t die out and survived the Armageddon. Those dinosaurs are the ones who evolved to nowadays birds.

The smaller size of their bodies required less food than those with bigger size. And it was also easier for them to find shelter from following disasters after the asteroid hit the earth. Maybe that was why they could survive and finally maintain their kinds until evolving to nowadays modern avian.

As a prove, you can trace chicken’s genetic ancestry to find out the look of the ancestor of this animal. And if you can do it far enough, you will find that its look resembles the shape of the fossils of dinosaurs you can find in the museum.

What is element number 118?

Oganesson is the element with atomic number 118. Very little is known about this element. It is classified as a non-metal and is expected to be a gas.

The International Union of Pure and Applied Chemistry (IUPAC) approved the name oganesson for element 118 in November 2016. This name honours Yuri Oganessian, a famous scientist.

This element was discovered by a team of Russian scientists at the Joint Institute for Nuclear Research in Dubna, Russia in the year 2002. A team at the Lawrence Berkeley Labs in California published a paper in 1999 announcing the discovery of element 118. But their results could not be repeated and the team took back their paper.

Later, in 2006, the element was officially announced by the researchers at Dubna and by the team at the Lawrence Livermore National Laboratory, who were working with the Dubna scientists.

When was moscovium made?

Moscovium is a synthetic element. Only a few details are known about it. It was earlier referred to as ununpentium, a placeholder name that means one-one five in Latin. The International Union of Pure and Applied Chemistry (IUPAC) approved the name moscovium for element 115 in 2016.

It was discovered in 2003 and announced on February 2, 2004. Moscovium was created and announced by the scientists at the Joint Institute for Nuclear Research in Dubna, Russia, and the scientists at the Lawrence Livermore National Laboratory in the United States.

The element is named in honour of the region where experiments linked to its creation took place.

Who made copernicium first?

Copernicium was first made in 1996. Researchers led by Sigurd Hofmann at the Heavy Ion Research Laboratory in Darmstadt, Germany, produced a single atom of copernicium-277. Very recently, atoms of copernicium-281 and copernicium-284 have been recorded during the decay of flerovium.

Copernicium gets its name after Nicolaus Copernicus, who started the scientific revolution with his theory that the Earth orbits the Sun. Copernicium is a synthetic metal. It is also radioactive and has only been produced in small amounts. As a result, it is used in research projects only.

Is flerovium radioactive?

Flerovium was first made in Dubna, Russia in 1998. The scientists from the Joint Institute for Nuclear Research in Dubna and the Lawrence Livermore National Laboratory (LLNL) in California led by Yuri Oganessian and Ken Moody jointly conducted studies on this element and prepared it many times. Thus The International Union of Pure and Applied Chemistry (IUPAC) announced its discovery in June 2011. The element gets its name in honour of Georgy Flerov, a Russian nuclear physicist.
