If nothing else, let’s take the species “human” as an example. If we put it on the biological tree to observe its status, when all are combined and subdivided, it will look like this:
Domains: Neomura - Eukaryota - Unikonta - Opisthokonta
Kingdom: Holozoa - Filozoa - Animalia - Eumetazoa - ParaHoxozoa - Planulozoa - Two Bilateria - Nephrozoa
Phylum: Deuterostome - Chordate - Craniate - Vertebrate - Gnathostomata - True jawed phylum (Eugnathostomata) - Teleostomi
Class: Osteichthyes - Sarcopterygii - Tetrapodomorpha - Tetrapoda - Reptiliomorpha - Amniote - Synapsida )-Mammaliaformes-Mammalia-Eutheria-Placentalia
Order: Boreoeutheria - Euarchontoglires - Euarchonta - Primatomorpha - Primates - Haplorhini - Simiiformes - Catarrhini
Family, genus and species: Hominoidea - Hominidae - Homininae - Hominini - Hominina - Homo - Homo sapiens - Late subspecies of Homo sapiens (Homo sapiens sapiens)
Therefore, according to the above-mentioned classification of humans in the evolutionary tree, if you want to evolve from primitive organisms to primates, the first thing to do in this handbag is to highlight the evolution of single flagella.
Then the flagellum is gradually moved to the rear of the organism, and finally it successfully turns into a silk-curling creature. In "The Epic of Life", players have already completed this evolution before, and this is almost the common end point for the players.
Because if you want to continue evolving, you will face a very difficult problem, that is, how the embryonic layer should differentiate after the fertilized egg, and the evolution of the embryonic layer determines the future path.
Some players couldn't help complaining about this on the forum: "Although the evolution of the embryonic layer has played a very important role in biological evolution in history, it is a bit nonsense to attribute all the differences in ghost hunting to the embryonic layer. Bar?"
A player below who has seen through the ghost hunting style replied: "It's been so long since "Epic of Life" has been launched. Haven't you understood the urinal nature of this game?"
"There is no need to talk about the future. Let us think back to the rogues and grass kings before and ask ourselves, isn't this kind of thing not magical?"
Of course, it is only the "Paradise Age" era. Players do not need to worry too much about the divisions faced by the curled silk creatures in the future. They only need to make some advance preparations.
So after making daily complaints about the Ghost Hunting Company, which under the guise of popularizing science, ended up doing some magical operations, players on the forum began to discuss how to get the embryonic layer.
As early as the previous "Ice Age" era, players divided the juvenile and adult stages to allow the primitive creatures they controlled to get rid of the simple division and reproduction model in the past.
Now that the "embryonic layer" appears in the "Paradise Era", the reproduction model will undoubtedly become more complicated, because now gestating organisms still requires complex embryonic growth processes.
The "Gastrula" will first evolve in the biological egg. After the "Gastrula" differentiates into "ectoderm" and "endoderm", the formation of "dimorphic organisms" will be announced.
For "dimorphic organisms", as the individual continues to develop, the "ectoderm" will later develop into epidermis and muscle cells, and the "endoderm" will develop into digestive tract cells and also serve as reproductive cells.
However, "dimorphic organisms" are only a transitional stage. The real direction for players to evolve is to evolve an additional "mesoderm" between the original "ectoderm" and "endoderm" to form the so-called "triple germ layer" biology".
Don't look at the difference between "bimorphic organisms" and "trimorphic organisms". There is only one more "mesoderm", but the number of evolution points required is greatly increased.
A player who did not read the game encyclopedia directly asked on the forum in confusion: "Why do you need to evolve to the three germ layers? Is there anything special about this germ layer? It doesn't feel particularly necessary and it costs points."
What some players on the forum like to do the most is to ridicule newcomers who don’t read game encyclopedias, so they immediately replied below the post:
"I won't go into detail about the rudimentary creatures of the germ layer. The creatures you are more familiar with on the earth currently, from mosquitoes to humans, from dinosaurs to Anomalocaris, are all three-blastoderm animals."
"Of course it doesn't mean that there are no diploblasts on the earth now, such as coelenterates and ctenophores. These antiques that survived from the 'Ediacaran Period', which is the 'Paradise Period' in the game, are actually living diplomorphic creatures. .”
This player who was enthusiastically providing science education to newbies was corrected by others, mainly because there was a problem with his description of intestinal animals:
"To correct the above statement, coelenterates were called coelenterates many years ago. Now the academic community has long renamed this animal type to the more rigorous name cnidarians."
After humbly accepting the suggestion, the player couldn't wait to type and continue: "Today, only cnidarians and ctenophores are left in the 'dimorphic organisms'. Even arthropods do not belong to the diploblast, which shows how ancient creatures they are. "
"So 'triple germ layers' is the direction we must evolve. So you understand why no matter how many points you spend, you must evolve your own species, right?"
Therefore, if players want to go further in the game, they must evolve towards the 'Three Germ Creatures', even though this process will take a lot of time and a lot of points.
After all, it can be seen from the above-mentioned evolutionary tree that the birth of the wonder of 'mesoderm' plays a very important role in living things.
If living things can have "mesoderm", "triple germ layer organisms" can evolve into bodies that are far more complex than "two germ layer organisms".
For "triblastomas" after birth, the "ectoderm" will differentiate into the epidermis and nerves, the coelenteron and digestive glands will come from the "endoderm", and the "mesoderm" will provide muscles, bones, blood, lymph and other Organization leaves room.
Therefore, compared with the more primitive "two-blastoderm organisms", "three-blastoderm organisms" can form systems such as breathing, circulation, movement, endocrine and excretion, and release mucous membranes on the surface to protect themselves.
But for players, especially those at the bottom who have been suppressed by high-level players for a long time, they found an opportunity to overtake around a corner.
