Spiders regularly spin silk and weave webs. Does it have thoughts, too? What is the scientific principle?

Spiders have no thoughts, and weaving webs is born and learned after natural evolution. Strictly speaking, spiders do not spin silk. Spider silk comes from a small hole in their stomach and is stored in the abdominal sac. So spiders don't spin silk.

In addition, there are many kinds of spiders. Some spiders have short lives, but others have long lives. Not all spiders can weave webs. Although some spiders can spin silk, their silk is not used to weave webs, but to escape.

Let's talk about the process of spider's web weaving. First, the spider hangs a silk thread from a height, which will sway with the wind, and then hang on an object, thus completing the layout of the first silk, and then around this main silk, the spider is laying out. Of course, a spider has no thoughts, but that doesn't mean it is a fool. It knows where there are often insects and it is also suitable for weaving nets, so it will go there to weave nets. In nature, it often happens that two spiders choose a position to weave a web, and one spider even cuts off the web woven by the other spider, but this situation is rare.

In fact, although spiders weave webs regularly, they have absolutely no thoughts and scientific principles. There are many kinds of spiders. Not all spiders can weave webs, but only some can. This is the instinct formed after the evolution of species, and people are born with it. Even the fishing nets we use are made of cobwebs. Like some big spiders, they hunt by hand-to-hand combat and don't rely on cobwebs at all. What's more, spider silk is just a tool it uses to escape and climb high. In addition, some spiders weave webs that are not as regular as expected, and even weave webs to keep themselves or spider eggs inside. In a word, not all spiders can weave neat and beautiful webs, and not all spiders can weave webs.

Therefore, only some spiders weave their webs regularly. To be sure, they have no thoughts. The reason why they weave webs is entirely out of instinct, hunting instinct, and an instinct engraved in the spider's gene sequence. Moreover, spiders are temperate animals, which determines that they can't have thoughts.
