Growing knowledge: "It is unbelievable that there have been five mass extinctions on Earth
99.9% of all species once died on this planet
250 million years ago, the earth's environment suddenly became dangerous
Before the extinction of the dinosaurs, 96% of the world's species died out quickly. This is the terrifying Permian mass extinction.
A mass extinction is a term with reservations. It began with the mass eruption of a large number of supervolcanoes. The land dried up, the oceans acidified, and life was almost wiped out. Forest vegetation was completely withered.
After watching: I only know about the extinction of the dinosaurs. I didn’t expect that there would be a new knowledge of the Permian extinction before that.
Increase knowledge: "Without the surviving species of the mass extinction era, there would be no living things today.
Our ancestors have withstood the cruel test of the times"
Post-viewing impression: After breaking and then standing up, one trades off the other!
As the natural environment changes, some old animals and plants are gradually eliminated by natural selection, and the fittest survives!
The remaining species are constantly improving and evolving to adapt to the natural environment
Increased knowledge: "The remains of the archaeologically discovered mammal-like reptile tridentate If you want to know what it looked like, imagine a meerkat. The difference is that it has no hair and is an oviparous animal, but similar to meerkats, they are They also live underground, dig holes with their big claws, and live in underground caves. Because of the shelter of the underground caves, they survived the era of mass extinction, which was day and night.”
After watching: Hakuna Matata, it is really interesting, Hakuna Matata, simple and easy to remember!
When it comes to meerkat, the first thing that comes to mind is this song!
I didn't expect their ancestors to have experienced such a difficult time. Fortunately, they lived in the cave to escape the catastrophe!
Increased knowledge: "Precious fossils found Two tricuspids huddled head to toe they were warming each other and they were evolving to warm-blooded animals, true mammals
Humans could not have evolved on Earth without creatures like the tridentate surviving the era of mass extinction."
After-view: Deeply realize that all things have always adapted to the changes of the natural environment to evolve and improve themselves
You can't change nature, you can only adapt to nature!
Unexpectedly, the distant ancestor of "Timan" is still an important link in the human evolution chain!
Increased knowledge: "Our ancestors were neither the largest nor the most ferocious, they just happened to live below the surface and luckily that was the safest refuge"
After watching: At this point I just want to say "Hakuna Matata! Don't worry about it from now on!"
The living environment in which you live is crucial to whether you can survive safely and reproduce for generations!
Growing knowledge: "Biodiversity gives life infinite possibilities, but diversity comes from difference from what scientists call reproduction
If you could reproduce asexually and you'd solve your dating troubles, just copy yourself when you want to have kids.
But there is a safety hazard in asexual reproduction, once every individual is exactly the same, a disease, a disaster may make you extinct, so life needs to merge.”
After watching: In the past, there was a wrong concept called "Kissing on a kiss"
Close relatives combined with family genetic diseases will also increase relatives, and the heritability is very large. Gene defects will always be inherited in the family, and there is almost no possibility of evolutionary improvement!
To maintain scientific rationality, we must oppose the CP combination of Jia Baoyu and Lin Daiyu!
Underwater sculptures at the Underwater Sculpture Museum in Cancun become home to a variety of corals
Increased knowledge: "Sometimes each year when the full moon is full, corals release countless eggs and sperm.
The image of the egg formed by the current is like the stars of the Milky Way
Eggs will randomly combine with sperm from other corals. The way corals mate in this group increases the probability of mixing genes, allowing the next generation of corals to acquire more diversity.
Mixing DNA from two different individuals creates a life like no other
Unlike father and mother
All children and each offspring are different from their parents and it is precisely because of this that the survival of the species is guaranteed
Hybrid genes are essential for the continuation of organisms"
Afterthought: Only by maintaining differences can all organisms evolve, improve and enhance their survivability in all aspects!
In this way, we can maintain the vitality of life and continue to continue life! The immutable species is in danger of being eliminated at any time!
Growing knowledge: "Mayfly spends a year in the silt waiting for the right moment to surface
Once the larvae of the mayfly become adults, they must go to the surface and move quickly enough to risk being buried in the belly of the fish.
If you escape from the water, you will stage a round of the most special life cycle on earth.
Adult mayflies can't eat, mouthparts degenerate, and they have no digestive system, which makes their bodies lighter and more suitable for flight.
An adult mayfly has only 24 hours to find the other half
Flocks of adult worms are flying all over the sky and brushing past the female worm. The fastest male worm will get the mating right of the female worm. Once the pairing is successful, the male worm's life will end. The female worm will find a suitable water source to lay eggs. meet death peacefully
The mayfly I, day and night, do everything possible for love and reproduction.”
After Viewing: New Knowledge! Let me know the source of the floating day
The "big cause" of the mayfly's life is to reproduce offspring and continue the population. How tragic and solemn it is to sacrifice life for this! Like an elegy for life!
Growing Knowledge paragraph summary: "Sexual reproduction makes the planet beautiful and is one of the greatest evolutionary tools for the complex and amazing life on Earth.
Without sexual reproduction, life cannot have the necessary difference. Sexual reproduction is a necessary condition for the inheritance of life on this crisis-ridden planet.”
Growing knowledge: There are about 37 trillion cells in the human body, more than the stars in the Milky Way
Cells undergo metabolism Hundreds of thousands of cells are shed from the body every day
Hundreds of millions of cells are dying in the human body The body must make new cells to replace these dead cells
This is the secret of our life-sustaining"
After watching: It turns out that the body is dying and being replaced every day. To a certain extent, the cells are "all kinds of yesterday died yesterday, and all kinds of today are born today!"
Growing knowledge: While most of the death process happens in our body, we can see peeling more intuitively when it happens on the skin"
After watching: It turns out that humans also shed their skin. I thought it was only some animals that shed their skin, which means that the cells in the human body died! Increase knowledge!
Growing knowledge: "Cells that repair themselves day after day over time will eventually fail
During each replication process, cells make some small mistakes plus some other losses. Over time, these damages will accumulate slowly. When the mistakes and damages reach a certain level, life will come to an end.
This is the mystery of death"
After watching: The human body is like a fortress. The original fortress was gradually exhausted and disintegrated from the inside!
Life is like a mine. We must know how to protect and expand resources, maintain a balance, not to over-exploit and consume resources, and reckless destructive mining. In the end, we can only "sit and eat"! Not worth the loss!
It's easier to create new life than to stop old age and death, and that's the best way to keep your genes alive
Increased knowledge: "Fire destroys everything but new life is born after the raging fire
Fire burns dead wood, allowing new plants to grow in cleaned soil
This is a natural law of nature
Death is an essential part of the cycle of life
Mother Nature's killer is to regenerate, but death also opens a window of hope for new life."
Post-viewing impression: Breaking and then standing I deeply realized that this is an important method of nature to renew all things! As the movie said, death on earth is another kind of new life!
The cycle of life and death circulates to replicate and balance all things, so that life on earth continues to evolve and grow.
Nature will eventually let us die with the wind, but it's not cruel, and innovation can give new life infinite possibilities
Death on Earth is another new life
Growing knowledge: "Salmon spawning is a journey that never comes back. Salmon have to go through hardships and tribulations to finally swim back to where they were born.
When the salmon has completed the mission of spawning, it will return to the end of life in peace and serenity
The earth is waiting for every life to die and it will recycle you and use your parts in all kinds of life
There is an element necessary for life in salmon, which is nitrogen.
When salmon die, trees use the nitrogen in the salmon as nutrients. Animal carcasses are broken down and then used by plants.
Trees thrive when they absorb nitrogen. These elements enter the ecosystem to help other members of the ecosystem.
There would be no salmon forest without salmon and everyone got a piece of the nitrogen feast.”
Post-viewing impression: All things go back and forth. Nature is an interlocking system!
Growing knowledge: "Everything in the world is connected and interdependent for a lifetime
We end the line of birth, life and death", forming a circle on this circle, the cycle of life and death goes on and on
Nothing really dies on this lit planet
but in a beautiful cycle of life forever.”
After watching: Death is a part of life and life is a part of death. Without death, there is no life without life. There is no death!
Each of us is just a speck of dust in the long river of life on earth
Growing knowledge: "All contingency arises from necessity. All things are different and intertwined.
Impermanence can also explain the changing beauty of life. The uniqueness of life is also precious because of its shortness.
We overcome all difficulties and overcome all kinds of difficulties just to have a foothold in this world, so we can't afford to do our best to live in this life."
After watching: Everyone's life is precious, so don't commit suicide, don't give up your life no matter how much pain or difficulty there is!
Only when you are alive will you have the possibility to work hard to change your destiny and improve the environment. Living is hope!
To love you, care about you and the people you love live well!
As long as you live, you can always find the value and meaning of life!
Every life has its own meaning and different brilliance!
Don't worry, the most basic thing in this life is to cherish every day, that is, to live well!
