Evolution is an incredible concept, showing us how all mammals, including humans, are interconnected. But where can we find evidence of evolution? Surprisingly, some of the clearest clues lie within our own bodies.
Many of our traits, both physical and internal, have been handed down through countless generations. While some of these traits no longer serve a practical purpose, they were once vital for survival. It’s fascinating to think that we still carry these remnants of our evolutionary past today.
For instance, consider how we react to cold weather. Ever noticed a pigeon puffing up its feathers in winter? This instinctive behavior helps retain warmth, showcasing evolution in action.
Similarly, animals like cats puff up their fur when threatened, making themselves appear larger and more intimidating—a survival mechanism passed down through generations.
One of the most intriguing pieces of evidence lies in our own arms. The palmaris longus tendon, found in some humans, was once essential for our tree-dwelling ancestors, like lemurs and monkeys, to swing from branches.
Over time, as humans adapted to life on the ground, this tendon became unnecessary and is now absent in about 10-15% of people. If you touch your pinky to your thumb and see a tendon pop up, you might still have it—a reminder of our evolutionary journey.
So, whether observing your reflection or the natural world, take a moment to marvel at evolution’s impact. It’s a dynamic process that continues to shape who we are today.
