Man is called an walking museum becausea)Embryogeny of man is an example of ontogeny repeats phylogenyb)Around 144 vestigial organs are there in human bodyc)History of mankind is well preserved and always cared ford)Man has shown an immense interest to know his past through paleontological excursions, archaeological excavations etc.Correct answer is option 'B'. Can you explain this answer?

Question

Answer

The organs which were functional in the ancestors but non-functional and reduced in the descendants are called vestigial organs.
Presence of vestigial organs in the most convincing evidence in favour of organic evolution and also supports the concept of disue proposed by lamarack.
In man, there are nearly 180 different types of vestigial organs.
Hence, Weisdersheim described Human being a 'Moving Museum of Antiquities' or a 'Moving Museum of Vestigial organs'.

Answer

Why is man called a walking museum?

Man is called a walking museum because of the presence of numerous vestigial organs in the human body. Vestigial organs are the organs that have lost their original function over the course of evolution. These organs were once useful to our ancestors but have now become redundant due to changes in our environment and lifestyle.

Presence of vestigial organs in human body

Around 144 vestigial organs are present in the human body. Some of these organs include:

1. Appendix: The appendix is a small pouch-like structure attached to the large intestine. It was once useful in digesting tough plant material but is now considered vestigial.

2. Wisdom teeth: Wisdom teeth are the third set of molars that humans develop in their late teens or early twenties. They were once used to grind tough plant material but are now considered vestigial.

3. Coccyx: The coccyx, also known as the tailbone, is a small bone at the bottom of the spine. It was once used as a tail in our primate ancestors but is now a vestigial structure.

Conclusion

The presence of vestigial organs in the human body is evidence of our evolutionary history. As we evolved, certain organs became redundant and lost their original function. However, they continue to exist in our bodies as a reminder of our past. This is why man is called a walking museum.
