Question

What is the principle of common descent?

Answer 1

Common descent describes how, in evolutionary biology, a group of organisms share a most recent common ancestor. There is "massive" evidence of common descent of all life on Earth from the last universal common ancestor (LUCA).

Answer 2

Explanation:

• The theory of common descent or evolutionary theory of common descent was proposed by Charles Darwin.  
• The theory is based on the principle that all the organism present on the Earth have evolved from a common ancestor and each species has diverged from a common ancestor in the past.
• This explained that species have evolved from the ancestral species but not present on this Earth in the same form from the beginning.
