如果外星人真的存在 它们应该长这样!

  Movies, TV shows, and video games have helped humanity paint a mental
picture of what aliens might look like if we ever run into them, but most of the
time those fictional depictions have little or no scientific backing whatsoever.
Researchers searching for extraterrestrial life don’t necessarily know exactly
what they’re looking for, but based on what we’ve learned about humanity’s rise
there’s a handful of things nature tells us are required for advancement of a
civilization. In the book “The Future of Humanity,” author Michio Kaku attempts
to answer the incredibly difficult question of what aliens might look like, and
this time it’s not just a guess.
          Kaku consulted with exobiology experts and theorists who specialize in
hypothetical alien life forms which have developed on far-off worlds much
different from Earth. Using that accumulated knowledge, Kaku came up with a very
basic list of criteria that any intelligence alien race would need to have in
order to reach a level similar to humanity.
          As the New York Post reports, the requirements that Kaku has dreamt up are
essentially the same capabilities that scientists believe have allowed humans to
progress in the way that we have:
          Stereo vision – Two eyes capable of focusing on a single object are
something we typically associate with predators here on Earth. Prey animals
often have one eye on either side of their head which allows them to spot
threats and escape quickly, but that type of ocular setup is poor when it comes
to hunting. Kaku suggests that most if not all “intelligent” alien races would
have originated as hunters, rather than the hunted.
          Thumbs – Scientists have long believed that evolution which led to
opposable thumbs was a huge factor in the rise of primates. A method of grasping
objects allows for the making of tools which, it is thought, is one of the very
earliest signs of intelligence as we know it. It makes sense that aliens would
have followed a similar path.
          Language – This one is a bit tricky because it’s incredibly non-specific.
The key here isn’t just the ability to communicate with each other in the moment
— many animals have species-wide methods of vocal communication that could be
considered language — but also to relay information and pass it down between
generations. This allows the accumulation of knowledge over long periods of time
and gives new members of a species the chance to expand and “stand on the
shoulders” of those who came before them.
          语言-这是一个让人难以言表的问题,因为它是抽象的,不具体的。语言的重点不仅说的是彼此间的沟通能力 -
          These features obviously sound a lot like what we’re all born with, which
makes perfect sense. However, within this very basic outline there’s plenty of
room for variation. If aliens only need two eyes, a gripping appendage, and some
kind of language in order to have caught up with humans, there’s really no
telling what form their bodies have actually taken, especially on planets with
chemical makeup far different from Earth.
