Around 3 million years ago, our ancestors started using stone tools, which became more refined over time. Those with hands adapted for better grip and tool-making abilities had higher chances of survival. The modern human hand evolved with short palms, short fingers of varying lengths, enabling precision and power grips crucial for tool crafting and throwing. Another theory reckons that our hands evolved to throw and hold things accurately. Human hands have short palms and short fingers with varying lengths. These proportions make it possible to grip things in two ways that other apes (mostly) cannot. Scientists believe using these tools has led to our unique grips and hand structure.\n
