Heritable changes in population of organisms over multiple generations lead to evolution. Somehow nature makes us do some surprising things for our survival.
Not only humans but animals too, when in tight spot use their brain to simplify things so as to make sure that they can overcome any situation easily.
We stumbled across some best of these occurrences in wild animals where the craftsmanship is on another level.
So just stay with us till the end and enjoy what we have to present.
#1 Hermit crab moves into a tin can.
Every time a shell is removed a crab loses a potential new home so these canny crabs have found another source of housing. Each evening the ranges clear the beaches piling up the litter.
Now the crab do something extraordinary. This hermit has found herself a more modern home in a tin can.
With so few shells around, this is an ingenious solution, and she is not alone. This is a fast growing trend. An aluminium fizzy drink can make a best lightweight home, that’s worth fighting for.
Life in the macron tin isn’t ideal and the local rangers know it, so they leave seashells near the rubbish pile to help the homeless crustaceans. The crab normally want its body in the spiral of the shell because it’s far harder to grip a straight and slippery can.
There are plenty of option it’s about finding a snug fit among all can. Well she can be picky if she wants, moving house is an important decision. At last the perfect home is found.
#2 Octopus steals crab from the fisherman
Fisherman Steve knows that most crustaceans aren’t known for their IQ.
Once inside a trap they don’t know how to get out. The exit is obvious enough to us, but some animals just aren’t born with much in the way of brain.
But why this seafloor look like a crab graveyard.
Well there is another crab fishermen living near the cave and is much more creative one than Steve. The animal living here shouldn’t be a problem. Its closest relative is slugs’ snails and clams. It’s a giant pacific octopus, an animal with one huge advantage an enormous brain.
Taking body size in account only those of birds and mammals are bigger 2/3 of those brain cells or neurons are actually in its tentacle and it uses it all to approach the problem of crab poaching.
Plan A is to smother the prey.
With the metal trap in the way that’s not too successful but that huge brain get the octopus to get creative and to think of a dramatic different strategy.
Once inside there's an easy meal but it could be its last, as Steve pulls up the trap. Breaking in was easy but the octopus can do something crab finds impossible.
He knows how to get out leaving a trail of empty shells and an angry fisherman. these problem solving skills set octopus apart from all other invertebrate
#3 Orangutan saws tree branches
At a jungle hut, this female finds a saw.
Despite being totally wild somehow she has worked out what to do with it. Orangutan has opposable thumb that allows them to grasp and handle objects with more precision.
Over 20 years a rescue orangutan learned how to saw by watching people constructing huts here, but this is totally different and the wild orangutan, she seems to take pride in her work. Even clearing away the saw dust.
She’s so smart that she uses her feet to steady the branch.
Doing this task by a wild animal is totally remarkable but now she is not the only orangutan sawing. Spy orangutan has joined her and seems to be bringing out a competitive streak.
She is becoming more enthusiastic but for a novice sawing is tiring work and she lost all her momentum, then finally calls it a day.
Spy orangutan may have machine like stamina but it’s the astonishing and versatile mind of the real orangutan that won the day. She certainly earned her rest.
#4 Monkeys uses tools to open shells
In southern Thailand long tailed macaques are sometimes known as ling tarle “sea monkeys”. And it’s not hard to see why.
But this isn’t about having a good time. Like their temple visiting cousins they have got a clever plan they’ve adapted their lives to the rhythm of the sea, and twice a day low tide reveals a feast.
Nutritious shellfish. Trouble is shell are tough to crack, but ever resourceful these macaques have found a smart solution they’ve worked out that rock make perfect shell fish hammer.
Although clearly some macaques are little smarter than others, either way low tide provide a sea food bounty.
Stone tool is a real skill among monkeys but these macaques can only benefit from it being completely in tune with the cycles of nature.
#5 Heron uses bread to bait fish
Living in the grounds of a Hawaiian hotel, is a night Heron. The staff called him Hank. His home is an all-inclusive resource where food is literally thrown at you, but Hank always has trouble going towards food because of the larger swan.
When he finally does get his beak on the food he does something totally unexpected. He doesn’t eat it but instead appears to have a plan. Hank takes the bread, he places it in the water and he waits.
He could eat it at any time but he doesn’t.
Hank is catching fish by using bread as a tool and he clearly knows how valuable it is.
He doesn’t waste it on fish too big for him to eat but instead takes it for smaller fish.
So there you have it. Hope it enticed your mind a little. Nature is truly beautiful in its own ways. Not forgetting to mention people of BBC Earth, whom hard work and time invested makes us see the beautiful stories in nature in the best possible ways.
