All life on Earth has a common origin. In other words, that in the distant past, there once existed an original life form and that this life form gave rise to all subsequent life forms.

The theories contributing to Modern biology: The Cell Theory, Gene Theory, Homeostasis, and the Theory of Evolution by Natural Selection.
Thermodynamics is a field of study that covers the laws governing energy transfers, and thus the basis for life on earth. Two major laws are known: the conservation of matter and energy, and entropy.
Current evolutionary theory on the origin of life posits that the first organisms were anaerobic because the atmosphere of prebiotic Earth was almost devoid of oxygen.
When we follow the history and energy flow of life through pattern of fossils, we see many information about the past on Earth.
How have those adaptations and conditions influenced life on Earth as it is today?
There are three domains of life as follows: Archaea - Archaea are so named because they are believed to be the least evolved forms of life on Earth ('archae' meaning 'ancient').
It is not just for its own sake, but because it underlies a wide range of goods and services that is essential to all life on our planet. Here comes the need of environment science, in protecting environment for animals and plant both.
499847 Anaerobic and Aerobic Cellular Respiration Anaerobic and Aerobic Cellular Respiration Water was abundant on Earth when life was at a critical stage of development, and as with many things so abundant, they're usually incorporated into the infrastructure
All living organisms on this Earth do share certain molecular traits from that distant ancestral life form.
