Asteroids that wiped out dinosaurs helped shape the rainforest-research



The asteroid that wiped out the dinosaurs 66 million years ago may have done more than wipe out the most famous iconic megafauna that roamed the earth: it may have created a rain forest.

According to a new study published in an academic journal science, That may be exactly what happened.

The study examined Colombia’s fossil pollen and leaves to determine how the asteroid impact that wiped out the dinosaurs affected life. Although these findings do indicate that there are widespread impacts between species, such as widespread extinctions, the structure of the forest has also been affected.

according to Washington postWith the takeover of flowering plants, 45% of all local plants have become extinct. The forest canopy has become denser, and the rainforest has become more diverse and layered.

How did this change happen? There are many possibilities.

One of the ideas put forward by the researchers is that the asteroid itself will leave ashes. These ash may lead to soil enrichment, which may create a better environment for flowering plants.

Plants like conifers are also likely to be more fragile, which were originally widespread in the area. As we all know, conifers (cedars and pines in today̵

7;s examples) were once the main trees in the world. However, they are known for being extremely easy to catch fire and extremely high temperatures because of their thin bark. In the case of pine trees, both pine needles and resin are very flammable.

The third possibility considered by the researchers has to do with the dinosaurs themselves. As we all know, trees like conifers have become the main food source for many herbivorous dinosaurs. Therefore, the migration and feeding habits of dinosaurs may help maintain the previously open structure of the forest. Without dinosaurs, this completely changed.

All these factors are likely to work together. After all, it is possible to develop needles and resins that help conifers easily heat and catch fire, as a means of defending against certain herbivores.

However, although the facts are unclear, the final result is not surprising. After all, not only did the asteroid strike wipe out the dinosaurs, but it also wiped out the dinosaurs. According to scholars, at least 75% of life on Earth has been completely wiped out.

The asteroid itself is widely regarded as the Chicxulub impactor (also known as the K/Pg impactor), which formed the Chicxulub crater in what is now Mexico. This impact was unprecedented and led to this widespread extinction event, paving the way for a new evolutionary opportunity to permanently change the world.
