Active evolution may sound bluffing at first, but Reiner knows that it exists even on Earth where there is no transcendent magic.

A simple example is practice makes perfect.

When a person has a plan and scientifically conducts long-distance running exercises, then as long as there is no irreconcilable contradiction in the body, then he is bound to gradually adapt to long-distance running, and the results of long-distance running will get better and better, and he will reach his limit without external strength to change his physical fitness.

In this way, compared with ordinary people, his running is actually slightly evolved, such as swimming, such as shooting, and even such as learning, all have such effects.

What's the point of what human beings do if they can't grow through hard work?

But there is a problem with this workout process, that is, it may not be passed on to the next generation.

On Earth, many people think that the children of two athletes should also have strong athletic talent, and cite certain examples to prove it, but in fact they ignore that on Earth, becoming a famous athlete itself requires extremely high physical fitness, and the physical fitness of the athlete couple will be passed on to the child, making him stronger than his peers.

This is also a deviation in a sense.

However, ordinary children's children may not be able to inherit the results of their parents' exercise, and if they want to become an excellent person in long-distance running, they have to start all over again.

This way of evolution has great limitations in nature.

For example, if the young rainforest falcon does not have such a rich amount of oil on its wings, it may die in the first rainy season, leaving it with not so much time to evolve itself, and according to the information given to them by Baptiste, the breeding season of the rainforest falcon ends during the rainy season, and the newborn chicks will grow up within a month to become hunters with enough wings to withstand the rain.

In other words, the ability to produce this oil is something that the rainforest falcon is born with.

Comparing organisms that are similar in blood structure to the rainforest falcon, it will be found that the oil-producing organs are common, and only the rainforest falcon is unusually developed, which is obviously related to the environment of the Erasmus halfplane.

Baptiste's theory is that the rainforest falcon survives the rainy season by secreting oil into its feathers during a storm, and then passes on this trait to its offspring, and the trait is fixed over generations.

"Everyone, please come with me."

Baptiste didn't say much, and led the people of the magic expedition to the fourth floor, which was extremely dark although it was on the highest point.

"This area is bred with creatures that are active in the Erasmus semi-plane during the dry season, they prefer dark environments and only move at night, some of which I have experimented with."

Baptiste pushed open the door and saw a huge cage in the room, and in the cage, a pair of dark green eyes were staring straight at Reiner and the others, which made people's hearts tremble.

It wasn't until his eyes adjusted to the darkness that Reiner saw that it was a wolf-like creature, except that it had webs on its paws and shark-like gills on its cheeks, which seemed to be able to adapt to life in the water.

"This is a sea wolf, similar to the creatures you've seen before, and has amphibious properties, but it has other abilities."

Baptiste turned on the light, illuminating the room.

Elimia saw that inside the cage were comfortable straw and water and food, and on one side of the cage, there was a mottled board with many characters on it, all of which were letters of the lingua franca.

"By training it, I made it literate."

Baptiste said lightly, slightly surprised by everyone except Reiner.

"Literacy?"

People know that the parrot can imitate human speech, but it doesn't understand what that means, it's just a poor imitation, but being able to read is a breakthrough in cognition.

"Can you show us that?"

Reiner said that performances such as animal literacy are nothing on Earth, but are fixed behaviors formed by conditioned reflexes and have nothing to do with cognition, and he wants to see how Baptiste "teaches" people to read.

Nodding, Baptiste inserted the board with the words through the gap under the cage, and the sea wolf saw it, wagged its tail and leaned into it.

Well, it's obvious a conditioned reflex.

Reiner thought silently.

Baptiste then spoke a few words to the sea wolf, roughly telling him to perform or something, and then made the sound of a common language letter.

I saw that the sea wolf immediately stood in its paw and pressed it on the corresponding letter, moving quickly without the slightest delay.

Several more similar interactions took place, and each time, the sea wolf was able to find the corresponding letter accurately and quickly, much to the amazement of others.

Reiner frowned, realizing that something was wrong.

Traditional circus performances are based on incentives and punishments, which eliminate additional instinctive behaviors through punishment and train target behaviors through incentives, so that the conditioned reflexes formed are similar to the simple thinking mapping of "as long as you stand up and turn around twice, you can have meat to eat", and animals can understand.

But just now, the interaction between Baptiste and this sea wolf has no incentives and punishments at all, even if the sea wolf recognizes the letters, he will not get food rewards, and in order to achieve such an effect, in addition to long training, special individuals are also needed.

Judging from the appearance, this sea wolf should be no more than two or three years old, and there is not enough training time, so is it the reason for the special individual?

As Reiner pondered, he heard Baptiste speak again.

"This sea wolf is called Ral, and in addition to knowing words, it can also read simple sentences and express them."

To the surprise of the others, Reiner's brow furrowed even deeper.

"Ral, come and say hello to everyone."

Baptiste said, and then he saw the sea wolf's paw move its paw across the board, clearly stepping through the letters to step on a lingua franca.

"Hello, I'm Ral."

This sentence is somewhat grammatical, but there is no mistake in the spelling of the words, and more importantly, this series of sentences was spelled by the sea wolf without Baptiste's guidance, which requires an extremely strong memory without considering true intelligence.

Reiner crossed his chest in thought, observing the subtle expressions between Baptiste and the sea wolf.

As Baptiste continued his presentation, Reiner suddenly discovered a surprising detail.

Every time the sea wolf spells a sentence, he glances at Baptiste, not a gaze seeking instructions, but an observation!

This sea wolf is watching Baptiste!
