Since the discovery of the first exoplanet in the 1990s, scientists have found more than 4,000 exoplanets, some like the giant gas planets of our solar system, and others like earth-like planets. Some exoplanets may have very harsh environments, perhaps as hot as venus or mercury, or as extremely cold as other planets. Of course there are also exoplanets that may have relatively suitable temperatures, may be located in the habitable zone of a star system, are a potentially habitable planet, and may even be a living planet.

In the process of forming amber resin drops, sometimes some unlucky insects or other small animals are imprisoned in them, freezing their lives in this moment.

Birds are one of the most common animals we see, especially birds like sparrows, turtledoves, pheasants and magpies, which are often seen in flocks. However, one thing that is strange is that with so many birds, we rarely get to see bird nests, why is that?

In the history of human development, "Learning to use fire" Was undoubtedly a very important point, as through the manipulation of fire, human beings were able to process various ingredients in nature into easily digestible and absorbable cooked food, to exert a powerful deterrent on other animals, to dispel darkness and cold, to harvest light and warmth, and thus step by step, a glorious civilisation has been created.

Although scientists did find that people still have consciousness at the time of death, but the consciousness does not stay for a long time, may not have time to react, the consciousness disappeared

Tigers usually rest on the ground. As tigers living in temperate zones, the ability to keep their abdomen warm in winter is a critical factor, so the Northeast tiger has the longest abdominal hair among all tiger subspecies.

During the long evolutionary journey, the brain capacity and the complexity of the nervous system of primates have been increasing, and correspondingly, their intelligence has become higher and higher as a result

Sloth monkeys, the world's only poisonous primates

The existence of reproductive isolation, so that these situations can not occur, even if there are some individuals of different species sometimes complete the mating, but they generally can not produce offspring, or produce offspring can not continue to reproduce
