Can animals perform surgical amputations? The seems that they could not. But now a study shows that they could. Surprising tactic may be way to prevent entire colony from being infected by bacteria.

”In his 11 years studying ant behavior, biologist Erik Frank had never seen anything like it. He and his colleagues at the University of Würzburg brought Florida carpenter ants back to their lab in Germany to learn how they respond to injury. Most ant species treat thte injured or severed limb of a comrade by coating it with an antimicrobial goo. But the reddish-brown carpenter ants took a different tack: They bit the remainder of he limb off, effectively amputating it.”

God has rewarded the ants with intelligence design, which makes them  do things other animals could not.

“Scientists have discovered many ancient shoes around the world, including 5,500-year-old leather shoes in Armenia, 6,200-year-old grass sandals in Spain, and footwear as old as 8,300 years old in Missouri.”

So the question is: When did humans invent shoes?

“There may be evidence that humans invented shoes much, much earlier. Fossil tracks on a beach in South Africa may be shoe prints dating back up to 150,000 years, according to a 2023 study. ."

According to Genesis, mankind invented cities andmusic instruments very early, so why not shoes?
