We knew trees and other plants display signs of intelligence, but we obviously never expected them to sleep .
Clever trees defy Darwinian expectations by doing so .
While plants aren’t animals, they share all kinds of tricks. and eucalyptus sweats to keep cool .
They depend on animals to eat their fruit.
Now, a study , which was posted December 2 on the bioRxiv database says that “plants can scream. near stressed tomato and tobacco plants, the instruments picked up the crops' ultrasonic squeals from about 4 inches (10 cm) away… The noises fell within a range of 20 to 100 kilohertz, a volume that could feasibly ‘be detected by some organisms from up to several meters away’, the authors noted.“
Well, that is what some plants can obviously do.

Some pterosaurs were almost too heavy for evolution to have them fixed.
However, a new study published in Scientific Reports looks at some smaller ones, They were found in a private limestone quarry in Lebanon more than 15 years ago. They were assumed to have lived roughly 95 million years ago.
They probably fed on crustaceans, flying on long, narrow wings and catching its prey at the surface of shallow waters, as do modern seabirds like the albatross and frigatebird.
The pterosaurs had no ancestors.

"We are amazed by how similar Eobodotria muisca is to today's species," said Yale paleontologist Javier Luque, lead author of the study, published in the journal Proceedings of the Royal Society B.
This means that no evolution has occurred in 90 million years- The oldest modern looking shrimp have 160 million Darwin years behind them and even a 300.million tear old shrimp is a living fossil.

A trait of the Habsburg dynasty in Spain was the Habsburg jaw, that was most likely the result of centuries of inbreeding.
The line from the 16th to the 18th centuries that came to an end, when Charles 2 died in 1700, failing to produce an heir.
Now, scientists have said that centuries of inbreeding had brought this deformity on their faces.
This causes us to wonder at the goodness of God and to say that this deformity was caused by selection.- not the natural kind - of centuries of inbreeding caused by genetic homozygosity, when all descendants share the same genes to produce a human being.
Thus, inbreeding can spoil the great walks of God, who wants us to be elegant.

A dinosaur or 75-million year- old hadrosaur, found in the Dinosaur Provincial Park in Alberta, Canada, had a 7 centimetre wide blob of amber, containing traces of trees and sap-sucking aphids.
Scientist think that after the Prosaurolophus hadrosaur died, "it washed into a river, There the Prosaurolophus, The blob, containing an unlucky aphid, washed up against the bone and was pressed against it by the flow of water, the scientists argue. It was then covered in sediment for tens of millions of years, during which time the resin hardened into amber".
The episode can also be treated like the waters of The flood of Noah’s day can account for the sap and its content, that is the aphids.

If the earth was flat, there would be no Moon. That would be a hazard for people living here – and the moon is responsible for giving us tides.
Most scholars who wrote on the shape of the earth said that our planet was round.
One of the earliest writers to do so was the English monk known as Saint Bede or the Venerable Bede (673–735). In his book De temporum ratione (On the Reckoning of Time), he explicitly stated that the earth was round.
Iohannes de Sacrobosco (ca. 1195–1256) was a monk and an astronomer who wrote an entire book on the shape of the earth. Entitled De sphaera mundI (On the Sphere of the World), it was published in 1230. His argumentation sounds very modern:
“THE EARTH A SPHERE. -- That the earth, too, is round is shown thus. The signs and stars do not rise and set the same for all men everywhere but rise and set sooner for those in the east than for those in the west; and of this there is no other cause than the bulge of the earth. Moreover, celestial phenomena evidence that they rise sooner for Orientals than for westerners. For one and the same eclipse of the moon which appears to us in the first hour of the night appears to Orientals about the third hour of the night, which proves that they had night and sunset before we did, of which setting the bulge of the earth is the cause.”
Thomas Aquinas (1225–1274) was probably the greatest theologian of the Middle Ages. In his Summa Theologica, he described the earth as being round like a ball. He pointed out that it was not shaped like a shield.
In addition to books, we can also see evidence for a spherical earth in the symbols that the rulers of the Byzantine Empire and the Holy Roman Empire used. A coin minted during the reign of Emperor Theodeseus II (who ruled from AD 408 to AD 450) already shows the Globus Cruciger, which is Latin for “cross-bearing orb”. The cross symbolises the victory of Christ on the cross and the orb beneath it depicts the shape of the Earth.
The Globus Cruciger became a symbol of imperial power. For instance, a 7th century coin depicts Emperor Leontius holding this object.
A medieval painting shows Henry III, Holy Roman Emperor (1017–1056), being presented with this symbolic sphere. And a 13th century painting shows Emperor Fredrick I Barbarossa holding the Globus Cruciger in his hand.
It looks very round.There are some people who think the Earth is flat, for instance

Many people, even atheists think can life does not end when we leave this life. This can out during a test that that News Scientist refers to.
Some of the people asked were atheists, they do not believe in the after-life. However, They believed that the I never changes, that it keep on going unchanged, afterwards as over here.
