There are over 8.1 billion of us on the planet, and we’ve been around since about 190,000 B.C.E. And while we’ve made many brilliant discoveries and breakthroughs, we also have a knack for exhibiting downright strange behavior. Below, you’ll find some of the most fascinating and hilarious posts from Humans Doing Human Things on Facebook. This page perfectly encapsulates just how odd our species is, so enjoy scrolling through these photos that should probably be dissected by an anthropologist, and keep reading to find a conversation with psychologist Leon F. Seltzer, PhD! “Non-human mammals have only an incipient notion of morality, relating to protecting, specifically, members of their own family and, more generally, their species, against other species,” Dr. Seltzer explained. He also recommended checking out the work of Loretta Breuning, who has written many books on this topic. “I’d agree that altruism as correctly defined (often it isn’t) is a human phenomenon that benefits the self-sacrificer only in satisfying their personal moral dictates,” the expert shared. “That is, there’s no survival in their actions.” “Once something becomes habitual, it’s no longer able to lift our spirits, to improve our mood or state of mind, so we look for something new. This explains why polygamy, for example, is so common— cross-culturally and historically,” Dr. Seltzer continued. From people wearing bikinis in the snow to getting hairstyles that look incredibly similar to pineapples, there is truly no limit to what human beings can do. And apparently, we have the creativity to keep innovating and coming up with even more bizarre and hilarious behavior to exhibit. Robert Roy Britt wrote a piece for Live Science discussing why human beings are arguably the strangest species, and he brings attention to a variety of the bizarre things we tend to do. We lie, cheat, fall in love, kiss, and blush. We also have odd features such as fingernails, an appendix, an Adam’s apple and curly pubic hair. Many of us even part our hair, crack our knuckles, get goose bumps and shiver when we’re cold. Follow Bored Panda on Google News! Follow us on Flipboard.com/@boredpanda!
