Question

In evolutionary terms, can we say which among bacteria, spiders, fish and chimpanzees have a ‘better’ body design ? Why or why not ?​

Answer 1

Organisms evolve with respect to their surroundings and changing environment.

A chimp has an ability to climb trees and strong limbs. A bacteria has necessary enzymes and proteins; say apparatus required for decomposition and multiplication, fishes have a well adapted respiratory system, I.e., the gills to respire underwater.

If we were to be placed in such conditions with our current body types, humankind will go extinct due to the regressive change in habitat, temperature etc.

Answer 2

ANSWER:

$\red{\huge{NO.}}$ We can't say that there is a "better" body design. Because:-

■ as the organisms have evolved in the oassage of time according to their needs to survive in the environment.

■A chimpanzee is a multicellular, eukaryotic mammal. They have limbs capable of multiple actions like climbing trees, breaking nuts. They have a developed brain. Much of their behaviour is like human.

■On the other hand The bacteria which is an unicellular organisms. They were the first organism on earth, can survive in extreme conditions where other organisms can not.

■ Dishes as they live in the water, has developed gills unlike land mammals which has lungs. They have fins and scales which help them to survive in water.

■Hence there is no better body design. Evolution can't measure the advancement of body designs.
