The ancestors of Shotter and AIIMS were to fly longer. Here’s how we did this work

In addition to being happy to see, flights to birds are considered a symbol of freedom, and is a source of inspiration for humans to build their flying machines. This makes those birds abandoned the land -based lifestyle and it seems more interesting.

In our new study about a 56 million -year -old foam bird, I and my colleagues have shown that the ancestors of the birds of the ostrich and other large flying birds had gone away at a distance.

Many flying birds belong to Pelgaginathi, a Texumic group that has colorful in Central and South America, as well as ostrich, raz, AIIMS, Kaswariyez and Kiwi.

Unlike their big flying relatives, Tinmous can fly – but not too far. While spending most of their lives on earth, they fly only when a hunter is shocked. If you have ever been on a walk and a grice or anger. If you shocked, this kind of flight, known as scientifically bursting flight, will be familiar to you.

Since they are in the flight (or not too much), the fact is that Pelugaginatis is found on many different continents, namely South America, Africa, Australia, Australia and New Zealand – it was difficult for scientists to explain it.

When the theory of plate tectonics was widely accepted in the 1960s, the response seemed to be within the reach. All continents were once united as Super Continent Panjia, which gradually broken at the time of dinosaurs, which began to be divided about 200 million years ago. Scientists wondered if the continents could be separated from each other along with the continents living with them as well as the continents living with them.

However, it has once again been notorious for two reasons. One is that the flying Taminos is genetically near some of the flying palgenths than others. This means that ostrich, raz, amus, kosoori and kiwi did not shared the ancestors shared in one flight. Instead, in a remarkable case of parallel evolution, they all separated from each other.

The second reason is that genetic research suggests that Pelgaganath tissues began to separated for several millions of years after the breakdown of Panjia – too late for the Cantonnental Draft Theory to come true.

This means that Paulogantis had to make it to South America, Africa, Australia and New Zealand under his strength. Just worth flying in short bursts, a camoum does not make a chance to fly in a sea – but what will happen to Pelgaginatis from the past? Has the ancestors of today’s Pelogenat have made this long journey?

The collections of the Smithsonian National Museum of Natural History in Washington DC include almostly secured sterina, or breast bone, which belongs to an ancient Pilatesagnath, which is linked to 56 million years ago. It was a huge bird, about the size of a brown buggy.

Other researchers had pledged that the stronghold is a key piece of skeleton to determine the bird’s flight style, so it was a great opportunity to decide what the ancient bird was capable of.

Using a technique called Geometric Morphometrics, we compared the shape of the Lithuanis Storm with more than 150 living bird species. Our results show that Lithuage was not going to explode like today’s Tamus. Instead, its strongholds are the most similar in the form of birds, which flies a lot of distances, such as aggots and bugs. This means that, unlike their living relatives, Lithuances and other ancient Pelogenis were travelers of the world, which would be able to establish a new population in different continents.

Why did these birds fly up again and again?

It doesn’t matter how beautiful or impressive we are, it’s also difficult. If the species of the birds will find themselves in a situation where they can find all their food on the ground and do not have to fly to avoid hunters, it will probably move towards flying.

Nowadays, these conditions are found only on the islands, Dodo is probably the most famous example. Dodo was a flying bird that wandered in Mauritius until it disappeared in the 1600s.

Dodos had no natural hunter unless humans arrived at the end of the 1500s (bring other animals, including mice). This meant that Dodos did not develop a response to fear, and his records were coming closer to humans.

Back when Litherans and its relatives were alive, the world was very different. Just a few million years ago, dinosaurs disappeared. Along with large hunters around, the birds were preserved on the ground along the continents as well as the islands. And with a special bill tip organ, with a deep feeling of aroma, lithorous was appropriate to investigate food in the soil, so he did not need to fly into the trees to feed.

Therefore, wherever the ancient pelvic, wherever the world goes, it was placed on a course towards a flying or low flight capacity. The predators of the newlyweds have slowly evolved over millions of years, and gave these birds a lot of time to develop new ways to avoid themselves and defend themselves.

After the long -distance flying ancestors disappeared, we had a wonderful distribution of birds that can be explained only by the record record.
