These are parts that look or act similarly but evolved independently. A bird’s wing and a butterfly’s wing both allow flight, but their internal structures are completely different. This is known as convergent evolution . 3. Form Follows Function

The magic happens in how these parts are modified. By comparing the skeletons, muscles, and organs of different species, scientists can trace the lineage of life back millions of years. 2. Homology vs. Analogy

From the fins of a shark to the wings of a bird, the natural world is a masterclass in engineering. is the study of these diverse structures, revealing how evolution reshapes a basic "blueprint" to help animals survive in vastly different environments. 1. The Concept of the Morphological Blueprint
