What are the different dating processes of fossils

Introduction What is a transitional fossil? The term "transitional fossil" is used at least two different ways on talk. I call these two meanings the "general lineage" and the "species-to-species transition": This is a sequence of similar genera or families, linking an older group to a very different younger group. Each step in the sequence consists of some fossils that represent a certain genus or family, and the whole sequence often covers a span of tens of millions of years.

Radiometric Dating and the Geological Time Scale

Anabaena The Three Domains of Life As previously noted, stromatolites are most often described as biogenically-produced structures formed by colonies of photosynthesizing cyanobacteria. However, this is an enormous oversimplification given that the weight of scientific evidence suggests that all three domains of life the Archaeans, Eubacteria, and Eukaryotes appeared in the Archaean Era, and thus the so-called microbial mats would have contained representatives among all three domains. Just how and when the base of the tree of life split into the three main branches remains one of the most important questions in all of biology and science, and is the source of constant scientific dispute. Which of the prokaryotes came first, the Archaeans or the Eubacteria remains unresolved, and a consensus has emerged that these primitive microorganisms laterally exchanged genes further confounding attempts to validate what begat what during to course of early evolution on earth. Lateral gene transfer belies the concept of the single common ancestor see Woese,

Creation vs. Evolution

Petrifaction also known as petrification is a type of fossilization which leaves living organisms preserved as a type of stone. In order for this to happen, a specific set of circumstances has to be present when the organisms cease to live. When any living thing dies and begins to decay, an oxygen rich environment is usually present. This environment is full of microorganisms, insects and fungi that begin to colonize and break down the organic matter into unrecognizable material.

We have personalities and we have memories. We have desires and we have goals. So, the question is do these personal possessions stay with us after death? Fortunately, we have an account in the Bible that can answer many of our questions, and since this account was told by Jesus himself, we know it is true.
