Phylogenetics and dating with 1988 carbon dating of shroud of turin
Phylogenetics is the study of how species on Earth are related and often results in a graphic representation of the links.Much like a family tree, the phylogeny of a species can be shown using cladograms.There is room to be subjective in placement of some species in relation to common ancestors.This leads to arguments and disagreements about the evolutionary path of some species.
Unrelated species will not be on the same cladogram.
The molecular clock was first tested in 1962 on the haemoglobin protein variants of various animals, and is commonly used in molecular evolution to estimate times of speciation or radiation.
It is sometimes called a gene clock or an evolutionary clock.
For centuries, scientists such as Carolus Linnaeus have tried to classify organisms into like groups in order to figure out their origins.
At first, most of this classification was based on anatomy and similar structures or physical features.
This is based on the assumption that species become more complex over time.
