Humans Evolved From A Fish In The Cambrian Period

"Because it's unpalatable?" Qin Fei was a little confused when he heard this sentence.

"Good guy, it turns out that odd shrimps are also picky eaters."

"I thought that with such a huge body, it should eat everything, otherwise how could it eat him so big."

The food that is hated by the odd shrimp is a piece of meat that looks flat.

When Qin Fei wanted to know what this creature was, the system had already consciously transferred popular science memories into Qin Fei's mind.

It turned out that this creature was a worm from the mollusk phylum.

As for this worm, if you look at it directly, you can't even imagine that it is a living thing.

If he didn't know, Qin Fei would have thought it was a piece of meat.

Because it looks like a piece of meat, except that there is a mouthpart under this piece of meat, which is the mouth.

However, its mouthparts are also very sharp, able to plan off algae on rocks.

So, it is such a piece of meat, why does it make the odd shrimp feel very delicious.

Here is another very long survival of the fittest story.

During this Cambrian period, molluscs were among the saddest animals.

why?

But guys, try to imagine what a piece of meat would be like.

If you don't have a figure, you don't want an appearance. It just looks better, because there is a lot of meat after all.

In addition, they are still a poor group, and they don't have any valuable equipment on them, just the flesh.

You said what's the point of living like this? You can properly fight the zero point one scum of the zero point one scum, and you won't struggle twice if you are eaten.

Look at other arthropods, all kinds of graceful figures, with armor and pliers, not to mention handsome.

If you look at other brachiopods, although their strength is not very good, but they are beautiful and good at disguising, so it is not a problem to survive.

And you mollusk, what else do you have besides that body of flesh, tell me!

Maybe molluscs are also aware of such a problem, so they also want to protect themselves.

But the question is how to protect it. This is a very distressing thing!

Then, at that very moment, the mollusk hit upon a really great way.

Since you like to eat me so much, then I will make myself unpalatable and see how you eat it.

So, the back skin of the mollusk began to grow thick, and even secreted some small calcium spines.

When eaten by predators, these small spines secrete some disgusting and undead substances.

Let you eat, let you like to eat me so much.

Now I will help myself to add ingredients to make the taste "more delicious" for you to eat.

That's right, that's it.

As a result, molluscs have gained a consensus, and they have worked hard to develop in this direction.

Then on a certain day, the sun was shining brightly, the sea was quiet and serene, and the mollusk lay carefree on the green algae, eating happily.

But at the next moment, the sky and the earth suddenly went dark, and there was panic all around.

The tense atmosphere instantly rose to a certain height in the nearby sea area.

A terrible crisis has come to this sea area, that's right, the strange shrimp is here!

The mollusk reacted slowly, realized the danger, and wanted to escape.

But its chubby, flat body limited their movement speed, putting it in a life-and-death crisis.

Then, the next second, poof! Tragedy happened.

The odd shrimp had already caught it and put it in its mouth.

Well! I like this meaty food the most.

The odd shrimp happily chewed and swallowed slowly, but when it took the first bite, it suddenly froze, and found that something was wrong.

Then take a second bite, and a third bite...

Pooh!

The strange shrimp spit out the meat in one bite.

Fuck, why is this meat so unpalatable, is it eaten by shrimp?

As a result, the unpalatable molluscs suddenly exploded in the strange shrimp, and then held a group meeting to tell the next generation that these molluscs are not tasty, so don't eat them, or you will feel nauseous.

This wave of counterattack by molluscs can be said to be put to death and then reborn!

Then over time, some molluscs have thicker back flesh and eventually a shell.

This is the direction of evolution of mollusks.

Of course, at the time Qin Fei was at, it hadn't developed to such a long-term time.

The current odd shrimp is only when it is still eating molluscs with a surplus.

Those who have eaten before and have memories, when they see molluscs, they will ignore them.

And some don't know it yet, so they will eat it.

Finally, through the efforts of countless generations of shrimp, molluscs were finally removed from the food.

"I never imagined that molluscs would have such a showy operation. It's amazing."

"System, do you think there is a way for me to become like a mollusk, so that the strange shrimp will find me unpalatable when they see me, and then they won't eat me?"

However, Qin Fei did not wait for the explanation given by the system.

However, they waited for the second task issued by the system.

"Issuing a new task, eating fifty molluscs, and obtaining the mollusk common gene."
