Are you sure about that? Viruses too? (depends on your definition of "living" of course) To clarify: I don't know if there is or isn't, I just don't think anyone does.
- gnulinux 8y agoYes we definitely do (not counting virus) because all living things share ~5/10% of their genetic material (like you share 10% of your genes with some bacteria) [1] which is very unlikely if it were purely random. This is of course one evidence, there are more evidence towards this.
