BTW, remember that you're still expecting the base Tech Tree from me. If you make changes to the released file, they will have to made again in the file I send you.
It would be helpful if you just post the filenames of which specific files you want to have locked by me until I get their new version from you. I'll then make a future changelog for these explicit files which I can work down once I get these files from you.
On HLS, that's a pretty weak rationale. If you're that successful then you don't need the extra points.^^ I suggest 12, which is still half the original.
I'll increase it to 9 but will half the buildocsts from 800 to 400. So that should raise some attractiveness there.
I'd just lose the +10% Industry on the BM. Or maybe add +5 Morale for all those happy tree-huggers?
With +5 morale they'll consider it being a morale improvement and because of its high AI value will place it on any morale bonustiles that there is on a new planet - basically wasting alot of potential if no Temple gets to see these bonustiles. So if morale is considered, it has to be higher, at least +20%. Altarians already have worse morale than many other civs. The Arceans "SpaceGun"-thingy has actually the same problem and its even worse considering the Arceans have a access to the strong generic moral-branch...
Another, more easier to use stat would be population growth.
I'm not entirely sure that it should. It is, after all, a Trade Good and available to all via trade. In my particular game it just wasn't in any of the three tech trees. I'd be happy if you left it alone.
Only if the 2 races having it are actually included in your game. And then, they'll still have to firstly research these tech (it's midgame/lategame) and then, go on to finish the build of the improvement. So even if everything works out fine you won't have it for a long time.
But the thing that I find unbalanced the most is the approach that certain Trade Goods should be be exclusive to certain races. That's not fair. At least not until all races do have a certain TG also made exclusive to them. Just take a look at the Yor - they're locked out from everything on the Diplomatic, Influence & generic Morale branch (some other races as well) and be as it is these branches hold a boatload of GA/SP/TDs. And other races, like Terrans etc have it ALL, they lack none of it.
If you design a ship, then in a later game the game requires that you have ALL of the techs that you had at that point before it will enable that design, even if the ship doesn't use them.
That's not true, you only need to have the modules which your past designs used to be unlocked in your techtree - it's even irrelevant how these techs cam eto you.
The only thing that can prevent a specific design to be avialable is missing Miniaturization - but the game will inform you about this.
I took a snap of the population curve, but don't have a hosting site.
Do you want a link to a german pic-host? 
Just do a google-search^^ there's plenty around
The "explanation" for Divergent Evolution is totally bogus. It's interesting, but it has nothing to do with the technology.
Anyone care to offer a possible rationale for a tech that makes massive PQ improvements?
The only thing that comes to my mind is that if 2 sentient species evolve on a single planet they probably do so in different habitats and later on show each other techniques how to deal with an otherwise hostile terrain. They may also have to think about how to artificially manipualte the environment in order to establish grounds which could be used by both of them equally. So that's perhaps where a Biosphere Modulator comes in.
