1. What type of evidence must molecular clocks be compared against to estimate the split from a common ancestor?


Sagot :

The fossil record is the type of evidence that is used with molecular clocks to estimate the split from a common ancestor.

What is a molecular clock?

A molecular clock is an estimation of the times of divergence used for the study of biological phenomena.

Molecular clocks are based on fossils found for a given species and the mutation rate of a given genomic sequence.

In conclusion, fossils are used as point of reference to build molecular clocks based on the mutation rate of homo-logous nucleotide sequences for a given taxonomic group for which these fossils belong.
