At present, the earth has been born for more than 4 billion years, in such a long time, the earth is also transported out of a lot of organisms, but the earth has experienced many disasters, and the earth has also endured many asteroid impacts, which makes the life on the earth continue to decrease, and also give the opportunity for biological evolution, although we see the earth is a lot of species, but in fact, compared with the past, the biodiversity on the earth is simply too little.
For example, when the earth experienced an asteroid impact that led to the extinction of dinosaurs, it was indeed an opportunity for human beings, if dinosaurs continued to exist on the earth, then human beings would not have appeared in the diversity of species is the wealth of the earth, and now human beings have no way to see the abundant species before. Now many have disappeared from the earth, but the earth will leave evidence of them. For example, a team of researchers at the University of California recently discovered a particularly ancient animal.
Scientists found that this ancient animal is very likely to be one of the oldest creatures on the earth, at first scientists hesitated whether this thing is a living thing, because it is located on the bottom of the sea, maybe just a plant, it looks like a sponge, and then scientists found that this sponge lived hundreds of millions of years ago, for the currently known creatures, this is the earliest creature, and scientists said that this creature has many people have been using it as a brushing tool.
Generally speaking, the ** of pure sponge is very high, and it is also very rare, the sponge we use at present is different from the pure sponge in the impression, there are many ancient animals on the earth, perhaps some animals are older than the ancient sponge, but it has not yet been discovered, more than 600 million years ago, the sponge animal is also constantly thriving in the ocean, but unfortunately there is no evolution.

Scientists have found an ancient animal -—— sponge after research, it is likely to be one of the oldest creatures on the earth, at first scientists wondered whether this thing is a living thing, because it is located on the bottom of the sea, maybe just a plant looks like a sponge, and later scientists by extracting some things from this sponge, found that this sponge lived hundreds of millions of years ago, which is the earliest creature for the currently known organisms, and scientists said that many people have been using this creature as a tool for brushing dishes. The ** of pure sponge is very high, very rare, the sponge we use at present is different from the pure sponge in the impression, more than 600 million years ago, the sponge animal is also constantly thriving in the ocean, but unfortunately there is no evolution.

I know that this is a very old creature, and because it looks like a sponge, people have been using it as a dishwashing tool.

This is talking about the sponge creature of ancient times, which no longer exists, leaving only some marine fossils, because of its rough appearance, it does not look like animals or plants at all, so that when scientists first discovered it, they thought that it was a tool used by humans to clean and sanitize the seabed.
There is no definite question of which is the greatest, Edison, Newton, Einstein and other four great Chinese inventions are not all great! Each has its own benefits, but who can say that Einstein was the greatest?
Albert Einstein (March 14, 1879 – April 18, 1955), a world-famous American scientist, was a Jew, the founder and founder of modern physics, the proposer of the theory of relativity - the "mass-energy relation", the defender of the "deterministic quantum mechanical interpretation" (vibrating particles) - God who does not roll dice. >>>More

In the Philippines and Malaysia, the Acacia tree, known as the "oil tree", produces a sap high in petroleum. There is a kind of wild grass that grows widely in California, USA, and it also contains ingredients similar to "oil", and rodents such as yellow squirrels are afraid of its smell, so the locals call it "rat sorrow grass". >>>More
