    "The terrestrial creatures in the age of the gods, whether amphibians, reptiles, birds or mammals, all have six-limbed structures." Britain.

    "Aha?"

    Everyone who was used to the structure of limbs looked at a loss.

    ¡°Well~~ In the original academic circles, it was generally believed that this feature was actually inherited from ancient fish, originating from the pectoral fins, pelvic fins and posterior pelvic fins of fish.

    The reason is that the genetic code responsible for the pectoral fins in DNA was copied incorrectly and was repeatedly expressed to form the pelvic fins. If the same situation occurs again, the posterior pelvic fins will be formed.  "

    ""

    What should I say?  This situation is not impossible. The evolution of living things itself is due to mutations in DNA during the inheritance process.

    but¡­¡­

    "I'm sorry, can you first explain some terms for certain people?" Xiu suddenly raised his hand and suggested.

    That¡¯s it. If you want to popularize science, you need at least the other party to have the most basic conceptual knowledge.

    "Well~~ The so-called DNA is deoxyribonucleic acid. The ribose sugar in the nucleotide is missing one oxygen atom. This is the substance that records the genetic code. The molecular structure contains enough information to control genetic traits. The two ends of the deoxyribose sugar  Phosphates and bases are connected to form nucleotides, which are then polymerized into long chains. The two long DNA chains are paired with bases to form a double helix structure. The pairing rule for bases is adenine (a)  For thymine (t), guanine (g) and cytosine (c), except for a few viruses, this DNA structure is common to all cellular organisms. The DNA length of various organisms is different, and a human cell  The DNA contained in it is about 1.8 meters. The order of the base pairs in the DNA molecules of each organism's species or individual is different. The genetic differences possessed by individuals come from this. So  "

    ""

    It¡¯s amazing that someone can understand!

    "Of course, amphibians with limb structures also appeared in ancient times, but during the evolution process, that branch of species became completely extinct, leaving only sparse fossil data. According to scholars' speculation, the reason for its extinction may be because  Creatures with a six-limb structure can support the body more effectively than creatures with a four-limb structure, so in the competition for survival, creatures with a six-limb structure have gradually become the mainstream creatures."

    But Britain didn't care about other people's reactions and continued to talk.

    "Although I'm used to it, don't you think it's strange?"

    "Huh? What's weird?"

    "Don't you have any ideas when you see those big guys?"

    Britain pointed at the group of giant dragons outside with an unteachable expression on his face.

    "¡­¡­ah!"

    Of all people.  Only Feng Kan reacted!

    "Speaking of which, all vertebral creatures now have limb structures, but only giant dragons"

    This is it!

    Whether they are reptiles or amphibians, or even birds that can fly freely in the sky, they are all vertebrate creatures that live on land.  Without exception, all have only four limbs.  Just the dragon - except for the front and rear limbs.  There is also a pair of flying wings!  This is indeed a six-limb structure!

    "So~~ In the current Trantark, this is the only one that still maintains the form of the creature before the Chaos War. Although they are all subspecies, they still retain the most important features of the ancient dragon.  Basic characteristics.¡±

    ""

    It means that dragons and other creatures are fundamentally creatures in two different senses?  !

    "Well~~After that, after a long process of evolution, the intelligent creatures that were producedwell~~the intelligent creatures collectively called human beings evolved into four basic forms."

    ¡°¡­Four kinds¡­¡±

    Fortunately, the following content is somewhat understandable.

    "Yes, there are four types, one of which still basically maintains its original form in the world of Trantak."

    ¡°¡­Which, what kind?¡±

    "It's the Sea Clan."

    "Aha?"

    "Yeah~~Actually, strictly speaking, it should be a mermaid type human being."

    ""

    what to do?  The brain is no longer able to process the current information.

    "The other three types of humans are no longer what they used to be. The ones that have changed the most are the orcs."

    "Orcs?"

    "That's right, the orcs from the age of godshow should I say this? Their shape is actually similar to the structure of a human horse"

    "That's not God?  !  "

    The world where people are running on the ground  What about orcs other than people and horses?  It's the same thing. The upper body is in the form of a human and the lower body is in the form of a beast?

    "That's not all."

    "I've been thinking about it before, you can actually read minds, right?"

    Why is this ability always used in very subtle situations?

    "In addition to the humanoid horse form, the orcs also have another branch similar to the modern human form, namely the horned people/long-eared people or the race called the divine shepherds"

    "This is somewhat understandable."

    "However, these races who focused on strengthening their basic physical abilities did not belong to the mainstream society on the continent at that time. Magical perception and intelligence were extremely developed, and the first ones to establish a sound social form and mature civilization system were those other than the above  Another race besides these races.

    ¡ª¡ªThat is Yiren.  "

    ""

    "To be specific, there are actually two branches of winged people, one is the dragon-winged people and the other is the feathered-winged people. Well~~ This undead natural disaster master seems to be a member of the dragon-winged people."

    "It seems like you can imagine a specific image just by hearing the name."

    Was Trantark such a dreamy world before the Chaos War?  A world filled with angels and demons?  Just thinking about it makes me feel dizzy.

    "Ah! By the way, the modern humans in Trantac are actually descendants of the divine shepherds, and the dwarves are the descendants of the horned people. The orcs are still orcs, and the sea people are still the sea people. However, all human forms are different.  A lot has changed"

    It¡¯s because of the Drifter ¡°The Holy Mother¡±, right?

    "What about the elves and demons?"

    "Ah! They are creatures created by God. They are not natural creatures."

    ""

    What is this guy talking about as if nothing has happened?  This answer seriously affects the three views!  It feels like I can hear the sound of cracks in my deep-rooted ethics!

    "It can be said that all existing humans are descendants of the branch of humanity before the War of Chaos, but only the Winged People are a completely extinct human race. They were completely wiped out during the final battle."

    "¡­¡­Hello!"

    ?Then the skeleton stick in front of you is really a ghost?

    Although it¡¯s not scary at all.

    "As a race with outstanding abilities, the Winged People have been fighting on the front line during the War of Chaos, so it is not surprising that they were completely annihilated in the battle where even the gods fell one after another."

    "Yes, yes, history tutoring is really hard."

    Such intense brainstorming is really overwhelming for a while.

    Except for Feng Kan and Xiu, everyone else had their mouths half-opened, their eyes blank, and they were in a fugue state!

    ¡°¡­It seems that this break will be delayed for a long time.¡±

    ?¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­¡­

    The existing historical books of Trantark are severely incomplete, and they only have a rough understanding of the Chaos War, while detailed and accurate historical data have been buried in the long river of time.  Especially the dragon knights from the Jammings Empire.  Under the influence of the long-standing religious system of the Supreme Religion, its worldview and historical outlook are extremely biased, so the people who were exposed to the cultural shock for the first time were stunned and unable to carry out normal activities for a long time.

    But Feng Kan doesn¡¯t care about this kind of thing. He has always believed that understanding history is important.  But what is more important is how to go in the future.  Learning history is just to summarize past knowledge, experience and lessons.  It is just a means used to better open up the future path.

    ¡°To be honest, I can¡¯t wait to go to Gadethevaz to see it.¡±

    Speaking of which, for him.  Unknown and novel things are the most attractive.

    Huh?  He is obviously a nerd, so why do naturalists from the Renaissance era have the same interests?

    "Gugugu, if that's the case, then I will be merciful and help you."

    The skull who calls himself the Scourge of the Undead proudly puts his hands on his hips (actually he is holding his two paws on his pelvis) and spreads the two wings that are about the same length as his height with a "whoosh" sound, looking very impressive.  .

    No, maybe he is really amazing. The swaying cyan phosphorus fire in the two black eye sockets became brighter.

    ¡°Speaking of which, I haven¡¯t replied for a long time.After that, it¡¯s almost time to go back and show your face.  "

    As he said this, the light of cyan phosphorus fire bloomed.

    This is not different from the pale green color just now. It is a soft and bright turquoise light. It feels like sunlight pouring through the dense canopy of trees, making people feel peaceful and calm.

    This azure light spread rapidly, at a speed visible to the naked eye, like a cyan curtain drawn between heaven and earth.

    On the clear and sparkling small lake directly in front of everyone, as the azure light spreads, contrary to the impression, it seems that an invisible curtain has been lifted, and a green lake is like the entire lake.  The man-made buildings made of jade gradually reveal their solemn and steady appearance

    "¡­¡­this¡­¡­"

    ¡°I didn¡¯t expect to achieve the predetermined goal so easily. No one knew what to say.

    "Welcome to the greatest intellectual achievement in human history!"

    Natural Disaster turned around and faced everyone and said proudly.

    "The crystallization of endless knowledge and wisdom, the place where the most precious treasures in human history are stored - the Holy City! Garde Tewaz!"
