I was wondering (and hoping) that in packs and herds an alpha or leader will be appointed and possible also show up in the info of the individual (kinda like with jurassic world evolution). It would be a nice little extra to not just have the animals herd up together but also have them follow one animal. Possible the oldest animal. I know males will fight over a group of females but amongst the females conflict can also exist for being higher in rank. Most animals keep testing each other to see if they can go up so it would keep things interesting and give us something extra to look out for when observing the animals.
