A comprehensive review of scientific findings, published in prestigious scientific journals, is presented to explain how life from other planets evolved on Earth. These first Earthlings (archae, bacteria, and cyanobacteria) contained the genes and the genetic information for altering the environment, the "evolution" of multicellular eukaryotes, and the metamorphosis of all subsequent species.
These included exons, introns, transposable elements, informational and operational genes, RNA, ribozomes, mitochondria, and all the core genetic machinery for translating, expressing, and repeatedly duplicating genes and the entire genome. Prokaryotic genes were initially combined to fashion the first eukaryotes and/or were donated and transferred to unicellular then multicellular eukaryotes and then subsequently expressed in response to biologically engineered environmental influences, often in busts of explosive evolutionary change, as typified by the Cambrian Explosion.
Genes biologically alter the environment such as via the secretion of waste products, e.g. methane, oxygen, calcium carbonate, sulphides, ferrous iron, etc., which acts on gene expression. However, these genes and life on Earth did not randomly evolve. Evolution is metamorphosis. These genes were inherited from ancestral species who acquired these genes and these genetic instructions from living creatures that long ago lived on other planets.
