Faced with invasive alien species, the scientists found that invasive species is likely to adapt to their environment and multiply there. Similarly, if the arrival of extraterrestrial creature from the right environment, you can continue to grow, perhaps early life on Earth is born this way.
Scientists have discovered on Earth almost no original ecosystem, invasive species may also very common in the universe
NASA is currently looking for life in the solar system, scientists found there may be two places of life within the solar system is Mars and Europa, NASA has launched several vessels probe to Mars to find life on Mars, but so far still no find traces of life on Mars, so scientists set their sights on Europa that senior marine organisms may exist beneath the ice of Europa. The key point is that the search for extraterrestrial life detectors are thoroughly disinfected, can not let the microbial contamination of extraterrestrial environments on Earth, or if the discovery of microorganisms, so in the end it will not be able to distinguish whether born in extraterrestrial environments.
Since the ability of microorganisms to survive, from invasive species on the planet can be seen, the International Union for Conservation of invasive species such as the Group of Experts Genovesi spent a lot of time to find foreign “invaders”, they are in a protective District test species invasion, the scientists found that the invasion of alien species is a very common phenomenon in humans, for example, in the last century almost no humans can not reach the island, there are some species will arrive by way of a variety of possibilities islands or regions, so scientists believe that if the remaining pristine ecosystems exist on Earth, it would be like.
Faced with invasive alien species, the scientists found that invasive species is likely to adapt to their environment and multiply there, because there is no threat of predators, invasive species often result in more serious consequences, which can be seen in some of the organisms on the environment ability to adapt. Scientists also found in deep-sea hydrothermal vents some microbes can adapt to extreme environments, but here is where fewer invasive alien species, many extreme and remote ecosystems can successfully avoid invasive alien species. Svalbard islands are located near the Arctic Circle, where scientists discovered more than 1000 kinds of plants, but there are many kinds of non-native species born, scientists worry biological invasion is only a matter of time.
For extraterrestrial life is concerned, the situation still exists invasive species, such as may exist beneath the ice of Europa suitable temperature, if microbes on the detector into the Europa environment, then it is possible to multiply. Similarly, if the arrival of extraterrestrial creature from the right environment, you can continue to grow, perhaps early life on Earth is born this way.
