Biology is the study of life and is intimately linked to chemistry, genetics, evolution, and geology- and all in solid agreement. Biology is perhaps the most fascinating science of all! Modern biology serves as the best evidence for most of the biblical creation story’s “days.”
Of life’s major developments, only a very few are mentioned, but what is completely obvious from biology is the substantiated fact that specialized life forms such as plants, sea life, and mammals did not just suddenly exist. Instead, life had its early beginnings billions of years ago, perhaps even before sunlight, and has undergone countless changes- some gradual, others abrupt.
Some think evidence suggests that life first existed at around the time of a CO2/nitrogen atmosphere, temporary volcanic islands, and mild or nonexistent sunlight billions of years ago. Although biology and evolution describe how existing life adapts through mutations, it has not explained beyond speculation how first life originated, or how first life devised a means of metabolizing energy for the sake of sustenance and replication. In fact, life’s earliest ability to devise anything is unexplained. Currently, biology is to first life, as physics is to the Big Bang Theory. New and innovative science is missing.
If the earliest living cells were to resemble modern life, they had to have the ability to do many things simultaneously. Once there was a lipid membrane (cell wall), or capsule, with something worthwhile inside, there had to be proteins from amino acids selectively allowing that which is good into a cell through its membrane, while allowing that which is bad for the cell (waste) back out through its membrane. In addition, there had to be a means inside each cell for the cell to metabolize energy. There had to be within this same chance cell, a means of self-maintenance and reproduction. The known life forms, including the speculative ones, are not yet rudimentary enough to suggest chance generation- more knowledge of their smaller parts is missing. Simple single cell life is simply not simple at all.
Cells are like tiny factories made of chemicals and needing energy to function. They are biological machines. They are “alive” since they possess the ability to self replicate- a chemical process as well. Even the simplest of known cell life has a complexity rivaling that of a computer with its operating system.
A complete understanding of how life began awaits new brilliance from the likes of a new Darwin, or Mendel; or perhaps in the modern anti science religious era, a new team like Watson and Crick.
From the very brief overview of biology that follows in science’s creation story, an important point one should gleam is this: the cells called eukaryotes had the versatility to evolve, as described by evolution, into all advanced forms of life. Land dwelling seed bearing plant life would eventually evolve (or be brought forward) on land from life made of eukaryotic cells. Animal life in the sea (fish), and then dinosaurs (birds) would eventually evolve from life made of eukaryotic cells in the sea. Finally, mammals would evolve on land from life made of eukaryotic cells on land.
Eukaryotic cells are a common denominator for all advanced life. Like micro-miniature supercomputers, the early eukaryotic cell life forms equipped with their DNA awaited environmental and competition tested programming- billions of years of programming. Much of the programming apparently occurred by chance and resulted either in failure, no real advantage, or in successful advantage. The successful programming propagated its advantages through to modern times.
Some of DNA’s programming is shared throughout all of animal life- perhaps from the earlier prokaryotic cells that, through endosymbiosis, first developed into eukaryotes, but even more likely from ancient advancing life that no longer exists.
The embryos of fish, reptiles, birds, and mammals including humans, all look indistinguishable in their early stages of growth. There are areas within fish embryos and within mammal embryos that produce identical results when altered in a lab implying shared genes that control specialized growth processes for bone structures, etc…
Perhaps, if altered early enough, a fish embryo’s parts could be stimulated to produce a mammal. However, the specialized growth processes inherited by successive generations have either undergone programming in the sea to produce fish, or have undergone programming on land to produce mammals. They are “after their kind.” Fish and mammals are separate species that evolved separately- fish advanced in the sea and mammals advanced on land. Their common yet very distant ancestor would not likely have appeared to be either a fish or a mammal.
Rather than jump right into a detailed comparison between the Bible’s creation story and modern science, it is simpler to go through an entire overview of science’s creation separately, but with the biblical creation “days” highlighted. After the science associated with each biblical creation “day” has become chronologically located, a detailed look at each of the Bible’s creation “days” will begin including their six-day timing.
The chronology of Earth’s geological and biological development is evidenced globally by all applicable science. The major eons, eras, and periods from biology and geology as they pertain to life are included in the brief coverage of science’s creation story that follows.
