What are Homologous Structures?

Meaning and Definition


Definition:

Homologous structures are anatomical features that are derived from a common ancestor, even if they perform different functions in modern organisms.


Explanation:


Examples:

Organism Structure Function
Human Arm Lifting/grabbing
Cat Front leg Walking
Whale Flipper Swimming
Bat Wing Flying

All of these limbs have the same basic bone structure (humerus, radius, ulna, etc.), showing they evolved from a common ancestor.


In Hindi (हिंदी में):

Homologous Structures वे रचनाएँ होती हैं जो सामान्य पूर्वज (common ancestor) से उत्पन्न हुई होती हैं, भले ही उनका कार्य आज अलग-अलग हो।

उदाहरण: मनुष्य का हाथ, बिल्ली का पैर, चमगादड़ का पंख, और व्हेल का फ्लिपर — सभी में हड्डियों की संरचना समान होती है।


Key Concept in Evolution:

Homologous structures are used to show divergent evolution — where organisms evolved differently from a common ancestor.
