What are two theories that historians have about why prehistoric humans painted animals on cave walls

There are three theories that the prehistoric man might have painted animals on the walls of the caves. Perhaps the cave man wanted to decorate the cave and chose animals because they were important to their existence. The second theory could have been that they considered this magic to help the hunters.

Photography has changed its subject matter quite a lot over the past few years. in the 1800's, it was considered normal for families to have  post mortem photos of their loved ones, and now that would be completely unacceptable. i think that photographers have always pushed boundaries and have been eager to capture everything, it is just society that changes their boundaries.

Studying history is very important so that we learn from past experiences and don't repeat the bad ideas/choices that might have been made. it can tell us how cultures conducted their lives and you can learn about interesting facts you might not know. hope this ! : )
