Animal are the part of our society so it is our responsibility to protect them and take care of them. Love Animals Love Environment.
It is a widespread idea among the public that humans are the most evolved species on the planet, and monkeys are often spoken of as the example of animals that, so to speak, had the bad luck of staying halfway and not progressing towards the final perfect state, ours. This is all a gross misconception: it is not just that chimpanzee genes show more evidence of positive selection than ours, which makes them more technically evolved; but, above all, the different species have found different evolutionary paths to better adapt to their respective environments. And in doing so, multitudes of animals have developed capabilities that we can only envy as true superpowers. Here are some examples.
Tardigrades, the born survivors
Of the tardigrades, microscopic eight-legged creatures also known as water bears, it has been said that they will be the last survivors on Earth. Although these animals are most abundant in moss and lichens, they have been found in the most inhospitable terrestrial habitats. Some resist extreme cold and pressures, radiation, dehydration, lack of air and food, thanks to a state of latency called cryptobiosis in which they can remain for years. They are capable of surviving in space; And although their fate is unknown, they are present on the Moon, since the failed Israeli probe Beresheet deposited them there in 2019.
Studies have identified certain proteins that protect tardigrades from desiccation and their DNA from radiation damage, as well as a fluorescent compound that makes them resistant to ultraviolet light. But science has only just begun to discover the mechanisms that make them almost indestructible. However, like Superman, tardigrades also have their kryptonite: a recent study finds that they die in just one day at the temperature of a slight fever of ours.
The beetle that supports the weight of a car
It would be difficult to determine which is the most resistant terrestrial organism to crushing, but without a doubt the Phloeodes diabolicus, or diabolical iron beetle, is a good candidate. This inhabitant of the deserts of southern California lives in the fungi that grow under the bark, with which it actually blends in.
A recent study has revealed the structure of the exoskeleton of this insect that makes it capable of withstanding being hit by a car without flinching. For this, it has renounced its wings, locking its thick elytra, which are supported by a solid lateral structure. All this makes it a tank of nature capable of supporting 39,000 times its own weight. Researchers are already mimicking the beetle's armor structure to design, for example, stronger joints in aircraft parts.
Vultures, a bomb-proof stomach
Before we invented expiration date labels, humans relied on sight, smell, and taste to dispose of spoiled food. But it doesn't always work: for example, Bacillus cereus bacteria can grow without any apparent signs in a multi-day old pasta dish. And even if the microbe is killed by reheating food, its toxins can linger and be lethal. Faced with the weak stomach of humans, many other animals are capable of eating spoiled food that would kill us. Among all of them, the vultures stand out, who enjoy delicacies whose simple smell would make us vomit.
In 2014, a study discovered how they do it: these birds destroy most of the dangerous bacteria that they ingest in stomach acid, but curiously they tolerate the passage of lethal microbes, such as those that cause anthrax, botulism, without problem. , gangrene or septicemias. Later results support the idea that it is the vulture's microbiome that allows them to feed on rotten carrion without dying in the attempt.
The female mole doping trick
Man and other male mammals receive a hormonal boost from testosterone that usually gives them greater strength than females of their species. But in the case of the mole, an animal subjected to the harsh obligation of digging tunnels for a living, the female has found a solution so as not to be at a disadvantage compared to the male: to develop testicles. Your ovaries are actually ovotesticles; they carry a nodule of testicular tissue that does not produce sperm, but does produce male hormones at the same level as males. It is the only known case among mammals. A recent study has discovered a curious set of genome rearrangements in these females that allows them to acquire this hormonal doping without possessing a male Y chromosome.
The built-in compass of dogs
Man's best friend possesses abilities that we would already like for us, such as a sense of smell tens of thousands of times more sensitive than ours, which allows them to follow scent paths in the air as we see a path. The smell of dogs has been equated to the ability to smell a rotten apple in two million barrels, or to detect a teaspoon of sugar in two Olympic-size swimming pools. Of course, they also beat us in night vision. But recently two other superpowers of dogs have been discovered. On the one hand, their wet and cold nose is capable of detecting heat from a distance, something that probably helps them locate prey. Even more amazing is its newfound ability to orient itself through the Earth's magnetic field.
However, and taking into account that this ability has already been described before in various animals, perhaps we should ask ourselves why humans lack something so widespread (or even if we have it, as one researcher argues, it is of little use to us). at the same time we can believe ourselves to be the most evolved beings in nature.
