Posted August 31, 2019 12:30:01 When you look up at the sky, the only thing that seems to matter is your height.
But a team of researchers from the US and China has found that giant pandas, the largest land mammals on Earth, have the power to jump off buildings, leaping as high as 15 meters above ground level.
The team is now studying the abilities of the apes to jump over bridges, and to navigate the urban landscape with the help of an artificial intelligence.
Their results have been published in the Proceedings of the National Academy of Sciences (PNAS).
The study, led by the University of Illinois at Urbana-Champaign’s Thomas H. Pendergast and colleagues, found that the apes can jump from a platform to a platform as high up as 10 meters, and jump again at a platform height of 20 meters or more.
The apes are also capable of jumping from a rooftop to a rooftop as high and as fast as 30 meters, the researchers say.
“We don’t know if it’s because the apes are very good at using tools to get around or if they can get to higher ground without them,” says study lead author David Ehrlich, an assistant professor in the PNAS Department of Animal Science and senior author of the study.
“But I think it’s more likely they have a very good toolbox of jumping skills.”
The apes, which are native to Asia, are believed to have evolved as the largest members of their species, with a body mass of more than two tons, more than twice that of the chimpanzee.
In their natural habitat, the apes live on trees and shrubs and can climb and climb and jump from tree to tree.
The researchers studied the apes in a series of lab experiments.
In one, the team trained the apes on a vertical platform that was 20 meters (yards) tall.
In another, the animals climbed to a 30-meter (yards)-tall platform.
When the apes were released into the wild, they were tested for their jumping abilities.
After a month of training, the group had to use the platform and jump up to the 40-meter-tall platform to reach the height they were trying to reach.
The results of the test, which involved the apes jumping from trees to trees and from the platforms to the rooftops, were compared with previous experiments done with chimpanzees, suggesting that the chimps had higher jumping abilities than the apes.
“These apes are the only primates that we know of that can jump so high from a roof, jump from one platform to another and jump back to the same platform,” says Humbert Ziegler, a postdoctoral researcher in PNas Department of Anatomy and Evolutionary Biology.
“The apes jump so well because they have very sophisticated jumping tools.”
When the researchers released the apes into the field, they also tested their abilities on a number of obstacles, including a wooden fence, a roof and a steel pipe.
In each of the tests, the ape groups were able to jump higher than the other groups and reached a height of 60 meters.
However, in the two tests in which the apes reached 30 meters (meters), they failed to jump at all.
“When you look at the way they jump, they don’t have the tools to jump from platforms to platforms, so they have to go through some kind of process to get to the height of the platform,” Ziegleman says.
“They have to climb on the platform, climb over it and then hop back up to it.
That is what makes them so good at jumping.
We don’t think it has to do with any specific skill.”
The researchers believe the apes’ jumping abilities come from the fact that they are able to use a range of tools to climb up from trees and up the roofs of buildings.
For example, the primates have developed a specialized claw that they use to pull down and free fallen logs.
The claw also has a similar ability to catch objects in the air.
Zieglius says the apes also have a strong sense of smell.
The group also found that some apes are capable of climbing in trees as tall as 50 meters, but they also had a strong preference for trees with smaller, smaller leaves, like those of a pomegranate or a rose.
“I think they are really good at finding the right trees for climbing, because they can use those for jumping up,” Zeglius adds.
In a third experiment, the scientists put a pair of apes together to see how they performed on an obstacle course.
One ape climbed from a tree to a scaffolding and then climbed a 20-meter high platform, while the other ape climbed the same scaffolding.
The ape that jumped to the scaffolding reached the same height as the other, but the ape that climbed the scaffold reached a higher height.
The other apes, by contrast, only managed to reach a height equal to the one the other
