In the abiogenesis theory, what caused molecules to not only animate, but also evolve survival and reproduction mechanisms?
Abiogenesis is the theory that life originated from non-living simple organic compounds. It is important to note that this theory is not yet fully understood and there are several factors involved in how it came to be. As the theory currently stands abiogenesis did not occur in rapid succession, rather over a period of millions of years and small evolutionary adaptations. This theory is widely accepted by biologists, since the age of earth is approximately 4.5 billion years old. This age provides sufficient time for the evolutionary processes to occur that has led to the advanced and complex life forms that exist today. Over a period of millions of years organisms were able to become more and more complex over time and best suited to survive in their environment.
Answer and Explanation:
Biologists current accept the theory of abiogenesis as the basis for how life was formed on earth and how we have such complex species that we are familiar with today. We can support the theory of abiogenesis because all cells have a cell membrane. This cell membrane is a phospholipid bilayer that is considered a fluid mosaic. We have tested and proven that phospholipids self-assimilate into this bilayer in an aqueous solution. From this we accept that this is how cell membranes were first formed. Subsequent non-living organic compounds entered this phospholipid bilayer and gave rise to various organelles. This is generally accepted by the endosymbiotic theory that states certain cells consumed smaller cells through phagocytosis and incorporated their function to meet the needs of the host cell. From this we believe that eukaryotic cells were formed and subsequently over time, more adaptations occurred to make cells more and more complex. Eventually this led to the animation of organisms and various reproductive strategies.
