Over time, the earth can have several different human species, each unique by their sex-determining systems.
The study adjusted the timeline for the divergence of the evolutionary lineage that led to people and the one that led to chimpanzees and bonobos.
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) on Tuesday launched the Collaborative Intelligence (CINTEL) Future Science Platform.
The discovery indicated that this monkey species existed in Asia at the same time as apes, and are probably the ancestors of some of the modern monkeys in the area.
The footprints described in the new study, published in the journal Science Advances, were found during a recent survey of the Nefud Desert in Saudi Arabia.
In two separate papers appearing in the same edition of the journal, they revealed two distinct and fundamental processes underlying germline transcriptomes.
The results could be a huge boost to zillionaires like Amazon founder Jeff Bezos who see the 'colonisation' of space as an answer to the Earth's ever threatened resources.
