Is it possible for humans to evolve from plants?

are the same single-celled biological ancestor.

But evolution is going in a different direction.

If you really want to get to the bottom of it, it's just that the ancestor is one.

But when it comes to the different evolutions of animals and plants, they are two different directions.

So it is impossible for man to evolve from plants.

The most fundamental difference is that in the composition of cells, plants have cell walls, and animals do not have cell walls.

When you see the letter of state in the courtyard reaching out to you that day, you will be glad to shake hands with him (or her or it), right?

In the final analysis, we all evolved from inorganic small molecule chemistry, but when it comes to the different evolutions of animals and plants, they are two different directions.

Vegetative estimates are.

Khan actually asked such a question.

It's whimsical.

Tree people: Only in Warcraft.

In the earliest periods, the primitive single-celled organisms will gradually become the most primitive algae plants, and as the original single cell will gradually evolve into multicellular. The algae in the water gradually evolved to the land, turning into a lower moss.

With the movement of the earth's crust, the plants in the sea gradually evolved into ferns. After that, ferns will gradually evolve into gymnosperms, and then the highest plants will appear, that is, angiosperms.

1. Algae. In the earliest period, the primitive single-celled organisms will gradually become the most primitive algae plants, such as green algae, cyanobacteria, etc., which originated in water and are very dependent on water, and their growth is also inseparable from water. With the evolution, the original single cell will gradually evolve into a multicellular, and the structure will gradually become more numerous and more complex.

2. Moss. The algae in the water gradually evolved to the land, turning into lower mosses, such as lichens, which are very adaptable to the environment.

3. Ferns. As the earth's crust progressed, some of the oceans would become land, and the plants in the sea would gradually evolve into ferns. At first, it was only an evolved nudibranch, with no leaves or roots, and only lived on land on false roots. Later, it will evolve into stems, roots and leaves, but it is still inseparable from water for reproduction.

1. The age of fungi and algae plants.

For nearly 3 billion years, from 3.5 billion years ago to 400 million years ago (late Silurian period), plants on Earth were only primitive and inferior fungi and algae. Among them, from 351.5 billion years to the period of bacteria and cyanobacteria monopoly, this period is often called the bacteria-cyanobacteria era. It was only from 15 billion years ago that eukaryotic algae such as red algae and green algae appeared.

2. The age of ferns.

From 400 million years ago, some green algae evolved into primitive terrestrial vascular plants, namely gymnoferns. Although they have no true roots and no leaves, they already have vascular tissues in their bodies and can live on land.

In the early and middle Devonian period, more than 300 million years ago, they experienced about 30 million years of landward expansion, and began to diverge in the direction of adapting to various terrestrial environments. In addition, bryophytes also appeared in the Devonian, but they never formed the dominant group of terrestrial vegetation, and they were only one side branch in the evolution of the plant kingdom.

Naked ferns became extinct at the end of the Devonian period, and were replaced by various ferns that evolved from them; By about 100 million years in the Permian, they became the protagonists of terrestrial vegetation at that time. Many tall tree-like ferns flourish, such as scales, reeds, seals, etc.

3. The age of gymnosperms.

From the Permian to the early Cretaceous, it lasted about 100 million years. Many ferns did not adapt to the changes in the environment at that time, and most of them became extinct, and the dominant role of terrestrial vegetation was replaced by gymnosperms. The most primitive gymnosperms (protogymnosperms) also evolved from gymnosperms.

The Mesozoic Era is the most prosperous period of gymnosperms, so it is called the Mesozoic Era as the era of gymnosperms.

Fourth, the era of angiosperms.

They are a group of plants that developed rapidly from the Cretaceous and replaced the dominance of gymnosperms. Until now, angiosperms are still the dominant group with the most species, the most extensive distribution and the strongest adaptability on the earth.

Throughout the occurrence and development of the plant kingdom, it can be seen that the entire plant kingdom has continuously occurred and developed through genetic variation, natural selection (and artificial selection after the emergence of humans), and has evolved along the laws from low to high, from simple to complex, from undifferentiated to differentiated, and from aquatic to terrestrial.

New species are constantly being created, and species that do not adapt to changes in environmental conditions are dying and extinction, and this long river of plant evolution will never stop and will never end.

The evolution of plants is roughly as follows: the primitive algae that live in the ocean gradually evolve into adaptation over an extremely long period of time.

The primitive bryophytes and ferns that lived on land made the original barren land begin to be covered in green. But their reproduction also.

Later, some primitive ferns evolved into primitive seed plants, including primitive gymnosperms.

and angiosperms, whose reproduction is completely free from the limitations of water and is more adapted to life on land.

The evolutionary process of animals is roughly as follows: primitive single-celled animals living in the oceans gradually evolved over an extremely long period of time.

There are a wide variety of primitive invertebrates, including coelenterates, flattened animals, nematozoa, molluscs and annelids, etc., which are increasingly complex in structure, but most of them need to live in an environment with water. Later it developed into primitive sections.

Limbs, which have external bones and segmented feet, such as insects, are more adaptable to the terrestrial environment and are detached from the aquatic environment.

The earliest vertebral animals on earth were ancient fishes. Later, over an extremely long period of time, some fish evolved into primordial ones.

The first amphibians, some amphibians evolved into primitive reptiles, and some reptiles evolved into primitive birds and mammals. Various.

The structure of animals gradually became more complex, and the living environment gradually changed from water to land, and finally fully adapted to life on land.

In short, the evolutionary process of living things can be summarized as: from simple to complex, from low to high, from aquatic to terrestrial.

Simple to complex, low to high, aquatic to terrestrial.
