Improved Natural Attack & Evolved Companion - Stacks?

[Captain Zoom]

A thought occurred to me and I thought I'd ask to make sure I'm not going to be doing something incorrect (I have an Animal Companion in a game and was thinking of doing this):

Do the increases to damage from Improved Natural Attack and Evolved Companion (taking the Improved Damage evolution) stack?

For example, Wolf Animal Companion has a bite attack.

Wolf takes the Improved Natural Attack feat for the bite.

Master takes the Evolved Companion feat and selects the Improved Damage 1-point evolution for his Wolf's bite attack.

Does the Wolf get the benefit of both feats? Or do they not stack?

Thanks

That's a good question that I can't answer.
But at least you could take evolved companion bite evolution. Now the wolf gets 1-1/2 strength on bite attacks.

I just thought about getting a Dimetrodon with the bite evolution and INA bite. That would be a 3d8 bite with 19-20 crit range and 1-1/2 strength to damage. Buff-able with spells.

Yes because they do a different thing:

One increases the damage to the next size.
The other increases the DIE size.

So if p.e. you had an attack doing 1d10, the feat would make it 2d6, the evolution 1d12.

I see, thanks.
So if I took the Dimetrodon above, the evolution would increase the 3d8 to 3d10?
In which order would you use the two abilities (INA feat and evolution)? It doesn't seem to produce the same results both ways.

Dimetrodon: INA first: 2d8 -> 3d8 -> 3d10. Evolution first: 2d8 -> 2d10 -> 4d8. Average 16.5 vs. 18
The giant gecko deals 2d4, for example. If applying INA first I'd have 2d4 -> 2d6 -> 2d8. With the evolution first it'd have 2d4 -> 2d6 -> 3d6. Average 9 vs. 10.5

i personally always apply abilities before feats and feats before equipment.

in the case of a summoner it makes them do slightly less damage usually, but it's no big deal.

in the case of dimetrodon it is a damage increase, but that's a rare sight compared to all the times i've used it
