LIVING FOSSILS! 99% OF ALL ORGANISMS FOUND AS FOSSILS ARE STILL ALIVE TODAY!

Why are most (99% at the family genus level) of all creatures found fossilized among the living and virtually unchanged over hundreds of millions of years? Isn’t evolution the opposite of what we observe? Such living evidence stands in defiance of evolution and eons of time.

Living fossils have remained relatively unchanged for billions of years.  Literally, thousands of common animals are found fossilized: fish, crabs, shrimp, clams, squid, crocodiles, and many others.  These animal families are notably alive and well!  And they have remained virtually unchanged over supposed millions and millions of years. Some were once believed extinct (such as the Coelacanth fish) but were later also found alive. These are major challenges for the theory of evolution.  The theory that needs things to change– needs organisms to evolve.  Why are most (99%) of fossilized creatures found alive today and virtually unchanged? Look at the horseshoe crab– back to the distant Cambrian layer thought to being some 541 million years ago– it is still the same!  Isn’t evolution the opposite of what we observe?

Common criteria for “living fossils” as a scientific concept or criteria used to designate living fossils:

• Prolonged geological duration (found in many layers of geologic ‘time’)

• Slow ‘evolutionary’ change (speciation only

• Gross similarity to an ancestral fossil (little to no change of vast periods of time)

• Very low taxonomic richness today compared to the past (vastly similar)

• Relic geographic range compared to the past (animal still lives in area where fossils are found)

• Phylogenetic (species unique diversification) inference of specific characters as plesiomorphic (‘primitive’ unique diversification)

• Phylogenetic inference of a genealogical divergence between other groups that diverged (assumed and not necessarially observed in the fossil record) in the distant past

above list has ‘quotations’ and (parenthesis) are mine

Living fossils: contentious but necessary? Whether it is horseshoe crabs, coelacanths, or gingko trees, taxa that allegedly display extraordinary levels of morphological stasis over geological time have called out for a special explanation since Darwin (Lidgard and Hopkins 2015).

Viewing extinct and extant representatives of these lineages side by side provokes an immediate judgment of similarity, regardless of whether it is justified. Why have these constellations of characters persisted for so long?”

Our aim…is to rethink the concept of a living fossils in a way that takes seriously both its routine use across disparate research questions in biology and the worries about its misleading inferences (such as creationists use of such data) in order to create new paths for productive research that yield a more unified theoretical outlook. We first highlight the value of thinking in terms of parts (characters) and wholes (typically, organisms or lineages) to better understand stasis. Then, we move beyond concerns that concentrate on categorizing living fossils.”

What needs to be specified (is) to understand how the living fossil concept plays the role of delineating what is in need of explanation and structuring a research program around different factors that are associated with long-term stasis

Should we expect very long-lived lineages to be common or rare, morphologically distant or average compared to related lineages?”

In summary, different disciplinary perspectives, data, and methods can be integrated within an organized structure of problems to achieve more comprehensive and unified answers to questions about slow or negligible rates of evolutionary change—stasis—for diverse kinds of parts and wholes in living systems.”
