Answer:

The gas that was absent in the primitive atmosphere was oxygen

Explanation:

According to evolution, the primitive atmosphere which was formed largely from volcanoes was devoid of oxygen.

The Earth's atmosphere is believed to have been composed of the following gases that was created from the early volcanoes:

  • Hydrogen
  • Helium
  • Carbon dioxide
  • Water vapour

According to evolution theories, oxygen was formed later on on the Earth's surface by simple organisms that developed the ability to carry out photosynthesis.

The atmosphere as we know it today, is made up of 21% oxygen, the gas that is quite essential to life on Earth.
