Evolution places severe demands upon fossils used to support it.
A fossil in an evolutionary sequence must have both the proper morphology (shape) to fit that sequence and an appropriate date to justify its position in that sequence.
The observation that certain fossils were associated with certain rock strata led 19th century geologists to recognize a geological timescale.
Like extant organisms, fossils vary in size from microscopic, like single-celled bacteria, to gigantic, like dinosaurs and trees.

Adding oxygen to earth's atmosphere allowed for the development of prokaryotic organisms, which need oxygen to carry out many of their life processes.

Which statements explain how this change occurred and how it affected life on earth?
Since the morphology of a fossil cannot be changed, it is obvious that the dating is the more subjective element of the two items.
Yet, accurate dating of fossils is so essential that the scientific respectability of evolution is contingent upon fossils having appropriate dates.
Small-scale permineralization can produce very detailed fossils.
For permineralization to occur, the organism must be covered by sediment soon after death, or soon after the initial decay process.
However, because of severe dating problems which are seldom mentioned, this alleged sequence cannot be maintained.Tags: Adult Dating, affair dating, sex dating
