Twitter Thread: The Human Body's Evolutionary Leftovers

Awesome, our bodies are like natural history museums. Apparently, we're brimming with evolutionary leftovers, and Dorsa Amir mapped out a way to play around with some of these in a fun Twitter thread.

Quick Tumblr Thread On How Dolphins Started

As we've all had hammered into our heads from an early age, dolphins and whales are mammals. Put extremely simply, dolphins started when some kind of weird pig/rat/wolf/hippo creature figured land was a bad move and there were more opportunities back in the water. That in-between thing looks like a failed science experiment. Nature has produced some strange things, like this cold-blooded freak-devil cave goat. For some mythological biology, here's Tumblr's take on dragon evolution.

funny dolphin tumblr thread | just-shower-thoughts kind dick move create animals require air, then confine them freaking ocean water-based-introspection Follow If are talking about dolphins they used be wolf like creatures due scarcity food they had hunt water so they slowly evolved into water mammals, dolphins still have claw bones but they are unnecessary and dolphins will get rid them with time and will develop abilities breath under water (This also partially applies whales)

Twitter Thread: The Human Body's Evolutionary Leftovers

An evolutionary anthropologist named, Dorsa Amir, shared a series of evolutionary leftovers that the human body seemingly carries for no reason at all. Kind of fun to look at the parts of the human body that have survived the test of time, and for what looks to us like no reason at all.

21 Times People Realized They Were Arguing with Someone Too Stupid to Argue With

At its core, an argument is a very common and simple act where two people who disagree on something deliberate over the truth and best course of action. When both parties are interested in a joint solution, consensus can be reached. The problem is that a solution also requires that the people who are arguing can actually agree on the point of the argument, how to actually argue, and the rules of objective reality. Here are some times when people realized they were talking to someone who couldn't be bothered to want to agree, didn't have the energy, or was just flat out dumb as rocks. In a similar vein, here are some of the dumbest arguments people have found themselves in.

You've probably learned about vestigial organs in Biology class by now. There are a lot of things that aren't important to humans any more but we've still held onto them in some way. If you've ever seen someone wiggle their ears, it's obvious. 

This video shows some of those unnecessary parts and why we used to have them. It also goes into detail about the way that some humans have actually lost those extra pieces. 



That's evolution at work.
