lemons,limes and oranges

[Guest]

are all citrus fruits artficially created variants? if so,what came first: the lemon,lime or orange?

[MrMistery]

No actually the orange tree and lemon tree are different species of the same genus that resulted due to natural selection. They were around long before agriculture

[Inuyasha]

aren't they from the citron genus and just have different specie names?

[MrMistery]

Look at my post Inuyasha. That is exactly what i said

if it is an important question with you, I think you can find a Genealogy tree of Rutaceae .
Citrus is an important tree so I think they did a lot of study about it.
they can build Genealogy tree by a lot of method ( RFLP,RAPF, ect)
if you need more, I can give you what we do to know where Cayen pinaple come from .

I love lemons and limes etc. Don't particulary like grapefruits tho.
