Relative dating of fossils activity

This group is dedicated to providing information about the scientific method as it concerns the idea of evolution in the Creation/Evolution debate. The site provides background information about stratigraphic principles and relative time, biostratigraphy (using fossils for relative dating), and radiometric dating. Understanding the ages of related fossil species helps scientists piece together the evolutionary history of a group of organisms.For example, based on the primate fossil record, scientists know that living primates evolved from fossil primates and that this evolutionary history took tens of millions of years.

Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods.However, by itself a fossil has little meaning unless it is placed within some context.The age of the fossil must be determined so it can be compared to other fossil species from the same time period.Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free.These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing.

One thought on “relative dating of fossils activity”

  1. by messages from hopeful (sometimes desperate) men - so much so that the average pretty girl with options doesn't last longer than a few weeks on the site before throwing her hands up in frustration and resignation and abandoning her account. Grizzled POF dating veterans who cut through newbie online dating hopefuls like female paramilitary troopers trained at mercilessly crushing and cannibalizing the unready and unprepared.
