explaining common ancestry

The common ancestor of Homo sapiens and Homo neanderthalis would have Homo characteristics, upright walking, hair thiness, speech, etc.
What features the common ancestor has depends on what level of common ancestry you are talking about.The common ancestor to me and my siblings are my parentsThe common ancestor to me, my siblings, my parents and my cousins are my grandparentsThe common ancestor to me, my siblings, my parents, my cousins, my grandparents and african bushmen likely lived more than 10 thousand years ago but less than 200 thousand years agoThe common ancestor to me, my siblings, my parents, my cousins, my grandparents, african bushmen and chimpanzees likely lived more than 6 million years agoThe common ancestor to me, my siblings, my parents, my cousins, my grandparents, african bushmen, chimpanzees and reptiles likely lived more than 200 million years agoThe common ancestor to me, my siblings, my parents, my cousins, my grandparents, african bushmen, chimpanzees, reptiles and bacteria likely lived ~3 billion years ago.It's just a matter of scale. How 'human' the features are depend on how close to 'human' the common ancestor was.
