The still-son flower fossil reveals the origin of the quilt plant.

140 years ago, Darwin called the origins of quilt plants a "nasty mystery" when they suddenly appeared in large numbers in the middle of the Cretaceous, but could not find clues to their ancestral groups and early evolution. on
13, Wang Xin, a team at the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences, published a study in Scientific Reports that Darwin saw in the fossil record that was not the "origin of quilt plants", but the eruption of the true twin leaf plants.
the origin of the quilt plant has otherwise.
quilt plant, the flowering plant, is the crown of the plant world.
it is the most evolving, most diverse, widely distributed and adaptable group in the world's plant circles.
is known to have more than 300,000 species of quilt plants in the world, accounting for the vast majority of the total number of plants.
true gemini plants are the most important branches of the plant, including most common plants, many of which are closely related to us.
such as cotton, soybeans, peanuts, sunflowers, apples, tobacco, mint and various melons.
after hundreds of years of research, it has been found that quilt plants had been found in the early Cretaceous and even jurassic, and that the origin of quilt plants should have been earlier.
since the origin of the quilt plant was not in the middle of the Cretaceous, what was that troubled Darwin? Wang Xin's team found a fossil named Jingzi Flower in 99 million-year-old Burmese amber.
the fossil is beautifully preserved and complete, with the quilt plant completeflower, petal, male, female, is a very typical core of the core of the two-leaf plant five petals.
this fossil, along with the flower and fruit fossils of other true gemini plants of similar times, tells people that the real gemini plants appeared on Earth in large numbers about 100 million years ago.
although the earliest recordofed tri-groove pollen of the true gemini plants was about 125 million years ago, they did not form a climate in vegetation at that time.
after about 20 million years of evolution, the true twin leaf plants really stand firm, in about 100 million years ago at the beginning and evening of the Cretaceous (commonly known as the Cretaceous) to flourish.
