Pollen analysis is then calibrated with SYNONYMS OR RELATED TERMS: APFCATEGORY: measure DEFINITION: A pollen density measure in which pollen counts per unit volume of sediment are corrected by estimated deposition rate (depth per year) to estimated influx (counts per cm per year), the same unit used for pollen rain" in modern samples.
Each taxon varies independently of the others making interpretation much easier than with percentages."SYNONYMS OR RELATED TERMS: pollen analysis CATEGORY: related field; technique DEFINITION: The study of fossil and living spores (of lichens and mosses) and pollen (of flowering plants); the technique through which the fossil pollen grains and spores from archaeological sites are studied.
In addition to the many plant and animal fossils in the paleontological collections, the Illinois State Museum is home to the North American Fossil Pollen Database.
Scientists contribute pollen data from study sites throughout North America to add to this body of information.
These skeptics do not provide scientific evidence for their views.
Another support beam has fallen from evolution’s explanatory framework as European scientists now report the discovery of flowering plant fossils in Middle-Triassic rocks—conventionally assumed to be around 240 million years old.
According to secular age assignments, flowering plants were not supposed to have evolved until 100 million years later!
They often refer to the Cretaceous as a time of transition.
Charles Darwin referenced the sudden appearance of fully-formed flowering plant parts in the fossil record as an “abominable mystery” in a letter to Joseph Hooker in 1879, and these new blooming fossils only intensify the puzzle.
Current understanding of the history of life is probably close to the truth because it is based on repeated and careful testing and consideration of data.
