What I did:
Read an article about the earliest example about locomotion of animals.
Summary (Includes what I learnt):
The article writes about the findings of an impression left by an ediacaran organism. These organisms can be flowerlike, some are like little plops of mud and some look like a palm leaf. They are the evidence of the earliest form of locomotion (the ability to move from one place to another). These traces have been fossilised by lava a million years ago.
A young paleobiologist went to the location where these fossilised impression were and noticed there was a slime trail that crossed the rock surface. These traces left behind seemed that the ediacaran had a suction cup foot to cling on to the surface not swim in the water.
But the question everyone wanted to know the answer to was that," why bother to move?"
Some assume this to be a relentless behaviour to be passed down in generations or they just moved for comfort. No one really knows the reason why.
