Same here, haven't really sat down to figure out what being in the same sphere means for the strains.
Could being in the same sphere be similar to the Haplogroupings used to determine a common ancestor in human genetics? For instance, my human Y chromosome haplogroup is R1a1, these subclads can be further refined to a very small group of people that are basically long lost cousins.
This is the kind of stuff that I'm talking about when I say I don't think it's ready to use as a source of information. If you've had headband you'd know you absolutely could not compare it to triangle just based on the "headband feeling".
If something is distantly related it'd be interesting to know HOW distantly.
If something is in a strain's sphere that's unexpected it would be awesome to know WHERE the relationship comes in.
If something is expected to be related based on marijuana lore but doesn't show up in the sphere knowing WHY they determined it to be so, either data available to be analyzed by a 3rd party or definitively mapping where either came from. Like why chem d and chem91 aren't related at all even though they supposedly came from the same plants and obviously share some traits.
I'm not a geneticist or anything like that. I'm sure plenty of people have an equal or greater understanding of the what, how and why that could make me change my mind but phylos hasn't done anything to make that possible.
I think that in a few years the phylos team will have better technology and access to genetics for them to make the most of their idea or someone else will come in and make it happen.
Still would be cool to have someone like Kevin talk about it or having a member of the phylos team go on something like the pot cast and talk about their project and address some questions/concerns from the community.
