Yes thanks, I had a look at baccata in a web search, but a question
arose over the fact of English yew compared to Japanese yew. It says
that Hungary or surrounding countries make it illegal to cut down yews
but they are not native there. The question is whether Japanese yew is
native to Japan, and if so, how in the world did they get there. Was it
an independent evolution of yew for England and for Japan and what is
the ancestor of yew to make that possible or was it that a English yew
some millions of years ago transported to Japan and evolved a different
species.

I guess the same question could be asked about English walnuts and
black walnuts native to USA. Did the English walnut and black walnut
evolve from distant ancient stock and totally independent of one
another or was the English Walnut in ancient past time transported to
the USA and evolved into a new species from the English walnut.

In both cases, yews and walnuts, I want to know if they evolved
independent of one another or dependent of one another?
