I didn't say they looked exactly the same, I said they looked similar, by which I mean they have broadly the same silhouette - snout, thick body, four thick legs, short tail. All birds aren't exactly the same - some of them look even more drastically different from each other than bears do - but you can still look at the silhouette of one and go "that's a bird". In the same vein, you can look at the silhouette of a bear and go "that's a bear".

Also, the cold of Solitas is described as being so extreme that not even Grimm can survive up there for very long, so in order to get bigger and stronger and smarter, as you have described, it only follows that the Grimm inhabiting Solitas have some sort of adaptation that lets them survive the cold longer than most. It's the only logical explanation, since Grimm don't have Aura or heating technology, which are the only two stated ways of weathering the cold. It has never been stated that getting bigger and stronger and smarter with age is the only sort of evolution Grimm go through (if it has, then please link it to me, I will admit I'm not as versed on Grimm biology as I'd like to be), so I'm leaving the gate open for possible specialised adaptations.
