As far as we know all life on Earth has the same DNA, and has had the same DNA for four and a half billion years, that is, we are all part of the same web of life.
However we are now sequencing the genome, and we may discover a creature on Earth or in the depth of the oceans with a different DNA. This would mean they are not part of our web of life and are truely alien. And it is possible they are living amongst us.
