I feel like the conservation part of planet zoo could be expanded in either dlc or in the base game with some new animals and a new function for the research center and a new building. How I would like to sea them expand this is with the addition of some recently extinct/ extinct in the wild animals. These could include both habitat and exhibition animals such as the splendid poison frog and the dodo. You could unlock those animals in the research center by researching the animal, which could be unlocked by researching similar animals. Then they could also incorporate a feature from Jurassic world evolution, which is the incubation of the animals in a new incubation center or in the vet building. These features could also spread awareness for research that is being done to bring those animals back. I do think this pack should not go back to far, but I feel like species that have gone extinct in the last 500 years could be added since their niche in the wild hasn't been filled yet and there is real life research being done to bring some of those animals back (like how we recently got the dodo's full genome). This suggestion is an expansion on another post which I'll link below.
Are there any animals I missed that you would like to see if this ever gets made?
