Lone Brain Planet [ABO]

Kilga pressed his hand on a black opaque glass cover, and the sensing glass lit up immediately. The two saw that there was a nest of black beetle-like animals inside, with invisible eyes and mouthparts like two scimitars. Open up and fold inward.On the body that is divided into two parts, the two front legs are abnormally thicker than the rear legs, and there are even fine and dense fluff on them, which reminds Wu Yi of the hairy legs of giant spiders that he saw on the Love Silk Star.Fortunately, this thing is not big, but one is the size of a human fist, and the two strong front legs alone are as thick as two human fingers put together.

Wu Yi didn't know this thing, although it looked a bit like a beetle, but the deformed body characteristics made Wu Yi unable to name it.However, they are all lying on the side of the spherical objects that are larger than their bodies, and they are trying to roll forward with their front legs.Wu Yi searched the memory bank in his mind, rolling the ball... seems to have seen it somewhere.

"This is the dung beetle on Earth Gate," Kilga introduced. "The people on Earth in ancient times even gave it a vivid name, called..."

"Dung beetle!" Wu Yi finally remembered.Yes, such a characteristic dung ball lover, of course, people will never forget it.But Wu Yi became puzzled again. According to the records in the ancient earth encyclopedia database that he had flipped through before, the dung beetle is a small beetle, only about the size of a human fingernail. It is definitely not so huge in the impression, let alone this weird What's the matter with his big thick legs? Could it be that he hybridized with crab-like creatures and grew crab claws?Drog also stared at the thick leg when he heard the words, as if he was thinking about the same problem.

"Hehe, you must be very curious, why does it have such thick front legs?" The experimenter Kilga's small lecture on biological sciences began, "Use it or lose it, Darwin's principle of natural selection, I believe you two You must have heard of it too, right?"

Yes, Darwin, a famous evolutionary biologist in the ancient earth era, who once rode the "Beagle" and lived in Galapagos Island on the west coast of South America for many years. , Even after thousands of years in the Milky Way Era, his reputation will always be recorded in the annals of natural science. Of course, Wu Yi and Zhuo Ge know him.

"However, Darwin's "Origin of Species" was delayed for many years after the first draft was written. Do you know why?" Comrade Kilga's desire for performance can no longer wait for Wuyi and Drog to answer, " Because there is one thing that has always bothered him, that is—the tail of the peacock. The tail of the peacock consumes a lot of energy. In the animal society that advocates the natural competitiveness of running fast and flying far, it is obviously a bug-like However, what is the reason behind its long evolutionary process to make its tail more and more beautiful and complex?"

Kilga's face was filled with a proud expression of "you don't understand, you can't answer it". However, when he heard Wu Yi's most simple and straightforward answer, which actually hit the question answer, he His expression was a little stiff.

Wu Yi replied based on her own personal experience: "Of course it is to attract the opposite sex." Hehe, why else would my baby Luoluo turn on the lights for me?Is it because I am handsome and have a good figure?

"Uh... well, you're right, but it's not accurate. In scientific terms, because apart from the 'natural selection' of the survival of the fittest, there is another important mechanism that is related to whether the race can continue , that is - 'sexual selection'."

"Cut, that's just what I said! Peahens like peacocks with beautiful tails, so they are willing to give birth to them, so that their genes can be passed on, so the tails of peacocks will become more and more over time. Bigger and more beautiful." Haha, the question that has troubled Darwin for many years, for Wu Yi, who only thinks about how to please Luo Luo, the answer only takes five seconds.

"Well," Kilga nodded, "so, the Dimen star dung beetle is the same. The females of them like to smell the feces pulled by the Dimen star rhino, which can make them go into heat. And the rhino feces are very heavy. , It is not easy to stick into a ball, and it needs very strong leg strength to roll them into the nest. Therefore, over time, the front legs of dung beetles rolling dung balls have become thicker and thicker, forming such a deformed physiological structure. "

Wu Yi looked at the lumps of golden balls and felt like he was about to vomit. It turned out that these were cow dung!The taste of this female dung beetle is too strong. Fortunately, my baby Luoluo does not have such a special habit, as long as she smells my powerful alpha pheromone, she will be in heat, hehehe.
