Further down timing gets a bit murky but it travels down to the first replicating molecules around 3,800 to 4,000 million years ago our first ancestor,probably formed around a volcanic vent in the early sea.So we are all cousins . The timing of splits was done using the molecular clock sampling the DNA Of present species.
