Assess how the determination that earth is 4.6 billion years provided support for the idea that all species evolved from a common ancestor.

Earth is 4.6 billion years old that provide support in a fact that the idea of all living being evolved from a common ancestor. The First Universal Common Ancestor or (FUCA) was born in the RNA world.

Explanation:

It has the ability to catalyze the bonding of amino acid into oligopeptide.

As the time changes, it gains the ability in translation system for doing error-prone genetic code. Thus FUCA is called as great grand mother.

After that, Last Universal Common Ancestor came which gives rise the ancestor of cellular organism and establish 3 domain that are Bacteria, Archea and Eukaryota. LUCA establish that contain genes with complex metabolism ability.

After 397 million years ago The first four legged animal came that are evolved from the intermediate species such as Tiktaalik.

Gradually time passed away and the tetrapods conquer the land that gives the birth of amphibians, reptiles, birds and mammals.
