Becoming human

Becoming Human What is a human? Scientifically they're Homo sapiens An animal who's intelligence is unmatched today, A creature whose own Past expierances guides his every move, but its the thing that you didnt expeirance that you know that make you so unique,That with the ability and need to always strive for better make him an unstoppable evolutionary force rivaled by none. We haven't always been on top there were others, just 50,000 years ago their were four different humanoids. Rewind another 6.5 million years and you have 20 human like apes. Homo sapiens the champion survivor even though we"re weak,slow,have small teeth,with no claws somehow managed to become the king of the food chain competing against beast like Lions,Tigers and Bears.Well It has to do with 3 pounds of tissue that puts all other evolutionary contenders to shame. It all starts with are friends Lucy and Selam, they are Austrolopethicus afariens the earliest human ancestor which lived around 3-4 million years ago. Standing in at 4 Ft. They resembled more of an ape then a human.They would walk upright for short periods at a time but what set them apart wasn't there brain, which was only about the size of a chimps.The difference came in the rewiring of the lunate sulcus of the brain moving forward, depleting space for the visual cortex making more room for the neo cortex.This is the part that Deals with cognitive thinking If it were a human these areas in psychology terms would be the parietal lobe,occipital lobe,and frontal lobe which gives us are higher functions . This change essentially created a more smarter chimp but laid the blueprints for our brains construction. The brain the most effective weapon develops gradually in each branch of hominid evolution.A major factor in why humans retain so much information is a human takes twenty years to fully develop while a chimp only takes 3 .The advantages to a slow developing brain allows for more information and taught skills
