Darwin clan pretty special, I’d say

 

“As the earth and ocean were probably peopled with vegetable
productions long before the existence of animals; and many families
of these animals long before other families of them, shall we
conjecture that one and the same kind of living filaments is and
has been the cause of all organic life?” asked the polymathic
poet and physician Erasmus Darwin in 1794.
“It was a startling guess for the time,
not only in its bold conjecture that all organic
life shared the same origin, sixty-five years before his grandson
Charles’ (Darwin) book on the topic, but for its weird use of the word
‘filaments.’ The secret of life is indeed a thread.” (DNA? PB)
