All matter in the universe erupted from a single event, the Big bang. It seems that all life on the earth also erupted from a single common ancestor during biogenesis.

Eukaryotic cells began to evolve into macroscopic organisms, the first of its kind 2.1 billion years ago. Several types of fossil appear to represent simple multi cellular forms of life found by the end of the Paleoproterozoic. Fossils known as carbon films, small dark compressions resemble circles, ribbons or leaves and some may resemble seaweed and algae. So the first multicellular organisms were the simple plant life that evolved. Even up until the early Devonian period the vegetation consisted of primarily small plants, the tallest predicted to be a metre tall.

Ramban explains the use of the term desheh eisev in naming the plants is related to the verb ÓéÐ (desheh), "to let the earth sprout". This verb refers to small underdeveloped plants and can apply to trees also, possibly indicating that all plants at this time were small and underdeveloped.

"A recent Nature article by Kevin Zahnle concludes that the sulphur isotopes in sedimentary rocks indicate that the photochemistry of the atmosphere altered dramatically 2.46 billion years ago, and that a major green house gas, probably methane had been removed3. In Zahnle's model, the action of ultra-violet light on methane produces a high-altitude hydrocarbon haze akin to the photochemical smog that shrouds Saturn's moon Titan. Zahnle states that "life 2.5 billion years ago seems to have existed under dusty yellow skies"."
