Possible sure, but you never know. My current game is a good example. Playing Egypt. I started on a river, which is nice, half desert half plains with a lot of hills, but no animals. I have cinnamon and copper close by. I researched husbandry last of all the 1st level techs, and then no horses showed up within 3 spaces either. Of course there is one 4 spaces away though. LOLPasture resources are everywhere, and there's always a possibility you end up having horses.
The same can be said for any ancient T1 tech. Unless you play OCC or something, you will have use for those techs.
