What are the three lines of fossil evidence that point to an early origin of life on earth? discuss each line and what it tells us about when life arose. what are the implications of an early origin for the possibility of life elsewhere?

The lines of evidence can be explained

Explanation:

From 3.8 to 2.5 billion years ago life forms began to be found in the archean era and the first life forms began to appear and as the world's landmass began to form the primary life forms were bacteria, as about 4.1 billion years ago earth's surface began to cool and crust began to stabilize. Early life originated water areas as single-celled organisms, Supercontinent of that time was Rodinia, the clay hypothesis suggests that the RNA is supposed to emerge and self replicate to form crystalline patterns subjected to the natural selection of species. The evolution of multicellular organisms like cyanobacteria paved the way for the formation of varied life that we know today.  The francevillian biota fossils, dating to 2.1Ga are the earliest known fossils.  The sedimentary rocks are used to date the rocks out for fossils, chemical traces of life have been found in Greenlandic rocks as a series of ancient metamorphosed rocks were found to harbor genetic information to a variety of living organisms stored in ice sheets.

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
