Have a big head or lead to extinction risk is huge: the sponge had a brain abandoned Bengal tiger has become endangered animal bigger brains to manipulate it more Sina Technology News Beijing on September 2nd news, according to foreign media reports, the brain bag has evolutionary advantages Obviously, but it also implies a huge price. For many of today’s larger brains, the advantage is that they are at greater risk of extinction. For a long time, the brain has been regarded as our most important capital. We are very clever, have conquered almost every corner of the earth, will be transformed into a variety of habitats suitable for our lives, and the development of more advanced technology to make our lives more convenient. Despite the fact that the brain is a very costly organ and requires a lot of energy supply, the existence of human beings has proved that these costs can be biologically rewarding. We have succeeded in finding a way to cope with the extra cost of brain evolution to larger volumes. But the larger brain is not as powerful as it is. In some cases, such as sponges and other animals do not even have brains, but also a very successful survival. Some researchers even believe that the sponge had brains, but they abandoned, perhaps because there is no brain can adapt to fixation on the seafloor life better. To understand this, we can understand some recent research revealed: larger brain volume in some mammals may have a considerable risk, and even lead to their extinction. Many of the world’s largest mammals are at risk of extinction. August 2016 a research paper pointed out that the earth’s largest mammals, 60% by the International Union for conservation of nature (International Union for Conservation of Nature, IUCN) belong to the level of threat (including vulnerable, endangered and critically endangered). Animals in sub Saharan Africa and Southeast Asia face the greatest threat, including rhinos, elephants, lions, tigers and gorillas. First author, Oregon State University College of forestry William · (William Ripple) in Poole said in a statement: "the world’s largest land animal facing the trend of more and more I fear that we will lose the animal, and the science that they had just how important." The gorilla will take years to take care of baby monkeys with its clever known this report brings together 43 wild animal experts results, published in the "biological science" (BioScience) magazine. The report highlights the fact that an animal conservation worker has long known that the greater the risk of extinction, the greater the risk of extinction. There are several explanations for this. Large animals need more food and more habitat, and often become the target of illegal hunting. In addition, their habitat is also due to the continued increase in deforestation and other factors continue to shrink. Forest, grass)相关的主题文章:
