After eating.

Liu Wei tried to understand what the cave people thought of the humans outside.

He didn't answer Liu Wei, but raised his head and looked at Liu Wei a few times from time to time.

Liu Wei could feel that he was deliberately avoiding this question, so he didn't continue to ask. For the entire Cave Clan, his death marked the disappearance of the tribe, and the words he didn't want to say were no longer important, as long as outsiders didn't bother him and went about their own lives.

Liu Wei changed the subject, hugged the little black panther that was gnawing on his arm, touched its head like a cat, and asked the cave people, "Can I take it to our camp for the night?"

The cave people shook their heads at first, fearing for the safety of their "loved ones".

"Don't worry, I'm a big fan of wildlife, including the black caiman you just ate!" Liu Wei added.

The cave people looked back at the crocodile meat on the ground, and then they understood why he didn't accept the food when he handed Liu Wei the food just now.

I thought about it for a moment.

Reaching out to touch the little black panther, he and the little black panther looked at each other for a moment, as if to tell it something.

The little panther screamed in response.

Then the cave people said to Liu Wei, "I'll pick it up tomorrow morning and take you to find the black panther!"

Liu Wei nodded, picked up the little black panther and called out to Deye, "Deye, let's go!"

De Ye was still picking his teeth with sharpened bamboo skewers, and all the half-cooked crocodile meat was stuffed between his teeth, which was very uncomfortable.

On the way back, the little black panther in Liu Wei's arms kept making a dull cry, it was expressing its uneasy emotions, but it did not attack Liu Wei, indicating that it trusted Liu Wei.

Back at the camp and sitting in front of the live broadcast phone camera, the atmosphere in the live broadcast room was still very lively.

", it's a corpse!"

"Hahaha, Ah Wei, the brothers all thought that you were killed and eaten by that primitive man!"

"Where did the primitives go? I just saw it without pants!"

"I saw it too, shy!"

"Hahaha, girl, what do you think?"

"The girl said she didn't dare to think about it, hahaha!"

Liu Wei looked at the barrage and smiled: "Brothers, let me introduce you to a new friend!"

Reaching out and beckoning to the little panther hovering around the edge of the tent, "Come here!"

The audience was puzzled.

Blackie?

Is it another dog?

The little black panther understood Liu Wei's gesture and walked to Liu Wei's side with small steps.

"Damn, is it a panther?"

"It's really a black panther!"

"It's so handsome!"

"It's the first time I've seen a black panther, I thought it was a fiction, but it's true!"

"I don't have any common sense at all, it's a shame that you've watched the live broadcast for so long, the black panther and the white tiger are the same principle, they belong to genetic mutations!"

"The Black Panther and the White Tiger are slightly different!" , Liu Wei looked at the barrage and said, "Half of this brother's words are right, they all belong to the mutant species of the original species, and the little black who stays next to me is the mutant species of the jaguar, except for the body color, it is not significantly different from the jaguar's lifestyle."

Blackie was adopted by the primitive man you mentioned, and he saved it from the mouth of the Amazon python!"

"Amazon python, hey~, I've seen the video, thief Jill Da!"

"The green forest python is the best!"

"The Titan Python is not convinced!"

"Prehistoric creatures, don't talk about it!"

It seems that there are still many snake fans in the live broadcast room.

"If nothing else, on this trip to Amazon, we should meet the green forest python, and we will give you a detailed science popularization when the time comes!", Liu Wei changed the topic back, "Now let's talk about the black panther!"

"And then the brother's point of view, why do I say that the genetic variation of the black panther and the white tiger are different? We are not referring to the difference of species, but from the perspective of biological genetics.

According to the analysis of known mutant species in the world, the offspring of the general genetic mutation will be difficult to adapt to the outside world, take the familiar white tiger as an example, too obvious body color makes it difficult to hide in the forest, and we all know that the hunting skills of big cats are camouflage and raiding, which hinders the white tiger in the hunting process, and even difficult to catch the prey, its color gives the prey a warning in advance.

The black panther is in a completely different state, the black fur seems to be a gift from nature, which is equivalent to an invisible field training uniform, which can better camouflage itself and improve its predation ability!

The panther is a nocturnal animal, when the night falls, except for a pair of eyes that can reflect light, the whole body seems to be drowned in the night, coupled with the jaguar's innate superb predation skills, it can be said that the prey it targets at night can basically only wait for death!"

"Well, the anchor has a point!"

"In such a comparison, the white tiger is indeed too conspicuous!"

"But it's pretty! it's enough to be pretty!"

"Pretty enough to eat?"

"Yes!"

"Hehe, woman!"

Liu Wei kindly persuaded him: "Don't get excited, let's mainly talk about the black panther."

The cause of the darkening of the jaguar's fur is actually a form of melanosis, also known as melanosis, which refers to the overdevelopment of dark pigments in the skin, which causes the skin and fur to darken, which is the exact opposite of albinism in white tigers.

Our intuitive impression is that the panther is black, but it is not, because our vision is inaccurate in the jungle where the sun is obscured.

In fact, its body is covered with the same rose-like markings as the jaguar, except that these markings are darker, brothers, look closely!"

Liu Wei held the little black panther in his arms, and the camera focused on the body of the little black panther, "See? The young panther's fur is darker, and as it gets older, its fur color will gradually become lighter, so if there are viewers who have seen the panther in the zoo, they will know that the panther there is not completely black, and the rose markings are obvious in the sun."

I learned from the primitive tribesman that he had seen an adult black panther in this jungle, and I will take you to look for it tomorrow, and if you are lucky enough to come across it, you will be amazed, it is so beautiful!"

"Looking forward to it!"

"Set the alarm clock and get up on time to watch the live broadcast!"

"I haven't slept in two days, I'll hold on for another day for the sake of the Panther!"

"You're really awesome!"

Liu Wei looked at the barrage and said with a smile: "Although the live broadcast is good-looking, you must pay attention to rest, and your body is the most important." ”

"We talked about the melanism of animals, in fact, there is not only one black panther in the world, but also tigers, zebras, wolves, seals and other species have melanosis, that is, they have melanosis.

Melanosis is believed by many people to be caused when an animal has too many sites, it is a kind of pigmentation, but scientists have found that MC1R and ASIP gene mutations can cause melanism in animals, so the academic community is more inclined to black panther melanosis because of genetic mutations, rather than pigmentation in a specific environment, and their offspring will normally be black, just like the little black panther in my arms, which has been this color since birth!"

The audience listened in a fog.
