Homologous Structure

Real World Example

Imagine you're trying to decide which smartphone to buy, and you notice that despite different brands, many phones have similar features like a camera, touchscreen, and apps. This is similar to how different species have evolved structures like a whale's fin, a bat's wing, and your arm, all of which share a common skeletal framework but serve different functions. Just as smartphones from different companies incorporate similar components to perform essential tasks, these homologous structures reveal a shared evolutionary blueprint adapted for various purposes in different species.
