Are there any special creatures that are different, and how does a species differ from a living orga

Theoretically.

The Milky Way includes 120 billion stars, which is a lot of numbers.

And there are countless galaxies in the universe that are identical to the Milky Way, even if the chances of life are low.

In the face of such a large base, the number of planets with life is still quite large.

There is no reason to directly conclude that there is only one lucky planet in the universe, the Earth, which has gone through the same primitive era as the Earth.

Even in the ocean of Jupiter's moons, they and we may have crossed the "boundary" (the boundary of the phylum, family, genus, and species), and they may have been silicon-based life, or even stellar life and electromagnetic life.

You know, all the life we know on Earth is based on carbon, and they may also be based on other elements or even matter.

For example, silicon elements, energy substances, etc.

Although there is the existence of the Fermi paradox, the Chinese writer Liu Cixin gave the law of the "dark forest" (cosmic sociology) to provide a possible explanation for the Fermi paradox. In addition, the British physicist Stephen Hawking's idea of not actively contacting extraterrestrial civilizations is also a manifestation of the law of the "dark forest". It should be noted that the Fermi paradox is only a suspicion of extraterrestrial intelligent life, and does not deny the existence of extraterrestrial non-intelligent life.

Fermi's paradox.

Species: refers to a group of biological individuals that are distributed in a certain natural area, have a certain morphological structure and physiological functions, and can mate and reproduce with each other in a natural state, and can produce fertile offspring.

And "a living being" is a specific concept that refers to a specific certain living being.

Generally refers to an individual.

Because of the diversity of genes.

Biodiversity usually has three main connotations, namely, the diversity of biological species, the diversity of genes (genetics) and the diversity of ecosystem groups The diversity of biological species refers to the richness of biological species (including animals, plants, and microorganisms) in a certain area, such as 1244 species of birds and 3000 species of angiosperms in China, that is, biodiversity and its changes at the species level. Genetic diversity refers to the genetic changes within individuals or populations of species, and the traits of organisms are determined by genes, and the traits of different organisms vary greatly, indicating that there are thousands of genes. The genetic makeup of different species (rabbit and wheat) varies greatly, as well as between the genes of the same species such as rabbits (white, black, gray, etc.), and each species is a unique gene pool.

Organisms of the same species refer to two or more organisms with certain morphological and physiological characteristics and a certain natural distribution area.

Organisms of the same species are organisms of the same population, either organisms of the same genotype or organisms of the same species.

For example, all grass carp in a pond are the same species, and all the grass carp in a pond are the same species.

In general, there are no reproductively isolated organisms.

One refers to the biological classification: "kingdom, phylum, class, order, family, genus, species", the organisms divided into the same "species", they have basic similarities in ecology and morphology, for example, all "domestic cats" belong to the same kind of organisms in species.

Of course, they will also be divided into different "species" according to different criteria.

What does that mean?

Is it a question that asks "Is there a living thing?" ”

Raise your hand ......

Yes, what do you say?
