A human has not been able to do what Spider-Man can unless 40% of the body was covered in sticky pads and they had impossibly large paws, according to new research.

Scientists in Cambridge and Australia comparing the load and footpad sizing of climbing mortals including spiders and geckos, encountered there is a width restraint when it comes to using sticky pads.

A gecko is about “the worlds largest” animal that can ascent utilizing this method.

They hope the study could help in the development of new adhesive substances.

In order to successfully scale a build the way Marvel comic book hero Spider-Man does, a human would need “impractically huge sticky paws – our shoes would need to be a European sizing 145 or a US size 114 “, said Walter Federle, from Cambridge University’s Department of Zoology.

Evolutionary limits

“We’d involve about 40% of our total person skin-deep, or roughly 80% of our figurehead, to be covered in sticky footpads if we wanted to do a convincing Spider-Man impression, ” Dr David Labonte, from the same district, said.

So, Spider-Man probably could not do what a spider can, but tree frogs, arachnids and geckos, can.

This is because of the percentage of their body skin-deep are covered under adhesive footpads, the researchers concluded.

The sticky pad percentage additions with torso width specifying an “evolutionary limit” to the size of swine able to use this climbing method.

Anything larger than a gecko would be required for “impossibly large-hearted feet”, they said.

The scientists compared the load and footpad width of 225 clambering animal species.

‘Stickier’ feet

“We were looking at enormously different animals. A spider and a gecko are about as different as a human is to an ant, but if you look at their paws, they have outstandingly same footpads, ” Dr Labonte said.

“Adhesive pads of clambering swine are a prime example of convergent growth, where multiple species have independently, through most varied evolutionary histories, arrived at the same solution to a number of problems.

“When this happens, it’s a clear sign that it must be a very good solution.”

The investigates hope the performance of their duties could contribute towards the development of manmade adhesives.
