How does research work?

So I'm playing rimworld for some time and i mostly played at all those advanced statt scenárista and never tribal. And as I start to play tribal I see that all basic tech needs more time to research since I have neolythic colony and research is medieval level. How do I raise this level of progress? I seemingly researcher every neolithic research I have, but still I have this problem which raises required research points needed, will I be stuck with it for rest of game since I started tribal???
