A small brain doesn't necessarily mean someone is less intelligent. In fact, some of the most brilliant people in history had relatively smaller brains. So, what gives? It's all about how our brains are wired, not just the size.
Think of it like a computer. Just because a computer is bigger, doesn't mean it's more powerful. It's all about the processing power and how it's used. Similarly, our brains have different types of processing power, and that's what matters, not just the size.
For example, birds have relatively small brains, but they're able to navigate and migrate thousands of miles each year. That's some serious brain power right there. So, maybe we should be looking at brain efficiency rather than just size.
