Many have read, heard or seen on TV stories about such creatures as centaurs, minotaurs, mermaids, griffins and other chimeras. All these creatures came to us from ancient myths and legends. Historians consider them to be fabulous creatures and they have good reason. In the end, evolution could not create such creatures that are both man and horse at the same time, bull and man, the same problem with fish and man, lion and bird. They all belong either to different kingdoms or to orders in the animal kingdom. The difference is not simply in the species of the animal.
However, is it possible to create such chimeras artificially in our time. It is unlikely that today's genetics are capable of this. But perhaps in the future, it may still become a reality.
The problem is that creating such chimeras is not very ethical. Especially if it is a mixture of a person with any animal.
However, what if we can create biorobot bodies that look like these chimeras and that we can use.
Many people have probably seen the movie "Avatar" ("Avatar" is a 2009 American sci-fi film written and directed by James Cameron - material from Wikipedia). They used avatars to get in touch with the inhabitants of another planet.
“Avatars” are artificially grown bodies controlled by so-called human operators. Management is carried out remotely. With the help of special equipment, the operator can mentally control the avatar's body from a distance as if it were his own. He himself, of course, is together, in which nothing prevents him from managing this body.
Now imagine that in the future you learned how to make such avatars. Then the ban on the creation of chimeras can be lifted. These will only be lifeless shells that must be controlled by a human operator. With the person himself, nothing will happen. It doesn't harm him.
Why do you need such avatars.

For example, for work underwater. If you create an avatar in the form of a mermaid, then this becomes possible.
A Centaur Avatar can be used to transport items in an area that cannot be used by wheeled vehicles.
Also, avatars can look like more than just chimeras. You can, for example, make an avatar in the form of a giant or vice versa in the form of a gnome. Surely, such bodies can also be suitable for some kind of work. An avatar can generally look like an alien from space. In general, in the form of any creature, limited only by the imagination of geneticists.
Perhaps in the future, various avatars in the form of all kinds of mythical creatures will be created in mass production.
Now imagine that a time machine will be created in the future. People will travel into the past. Then they surely can take these avatars with them.
It is possible that this is how various legends about various mythical creatures could have originated. That is, we, or rather our descendants, created them ourselves.
