1. More endurance than our ape relatives.
2. Better immune systems
3. Ability to eat starchy foods

"Evolutionary changes have given us a lot more endurance than our ape relatives.Part of this comes from anatomical changes. We have elasticated arches and tendons (such as the Achilles) in our foot. This conserves energy between steps, making the whole process more efficient. However, evolution has also granted us a physiological superpower. The number of cells in our blood has decreased dramatically. That means more red blood cells transporting more oxygen around our body. By keeping our body well supplied we have the endurance needed to outpace chimps.

Compared to chimps you have bendy feet. This is another adaptation that means you can walk efficiently.
This obsession with movement does more than keep Fitbit in business. It’s the reason humans are successful. The fact that chimps don’t move much limits where they can live. They need to be where food is within reach. This is why they’re only found in the rainforest, where their favourite fruit is everywhere. But if try and migrate elsewhere bad things happen. Food is so far apart and they have to travel such distances that their inefficient locomotion, combined with their fur, means they would overheat before they could feed.
The researchers behind this discovery also speculate our super-blood might be linked to endurance running. Thanks to it we can run further than any animal. Some hunter-gatherers put this to use when they hunt, tiring out their prey until it’s an easy kill. However, whether this played a big role in human evolution is debated (https://www.filthymonkeymen.com/?s=endurance+running)."

"Thanks to the Neanderthals – and our own adaptations to these strange environments – we have an immune system not to be trifled with. Key physiological changes include white blood cells that mature faster, along with a greater overall number of white blood cells."

"The human diet has undergone some fairly major changes. Fortunately, evolution has equipped us with a body that can deal with it. Mutations have increased our production of amalyse, which helps us break down the starchy foods which now dominate our diet. The fact you can eat large amounts of potatoes, rice, pasta, wheat, and more without suffering from crippling intestinal problems is all thanks to evolution.
These physiological changes may pre-date farming. Hunter-gatherers also switched to a much starchier diet than chimps have. As we moved further north, fruit no longer became a viable food source. We had to supplement it with roots and tubers. Accordingly, modern hunter-gatherer populations show that same spike in amalyse production farmers have. Our starch digestion might be an ancient superpower that made farming viable."

we are apes that fell out of the trees and moved on in the savannes

while apes kept on swinging in the trees, we explored the world and adapted to the most diverse habitats

in endurance, humans are number 1
3 million years ago, we lost our fur, and have sweat glands all over our body allowing us to get rid of excessive heat in endurance efforts
at the same time we got melanine, our skins turned black to protect us from the sun
