The relative time of divergence from a common ancestor can be estimated by comparing the nucleotide/protein sequence.
<h3>What is sequence homo-logy?</h3>
In molecular biology, sequence homo-logy means the degree of similarity between sequences due to a common ancestor.
A sequence is a given fragment of a single DNA strand where nucleotides are arranged in a specific linear order.
Divergence or separation between lineages is directly proportional to the level of sequence homo-logy.
In conclusion, the relative time of divergence from a common ancestor can be estimated by comparing the nucleotide/protein sequence.

Biological systems do not contradict the second law of thermodynamics. Even in this case, entropy is still always increasing. Biological systems can only decrease their own entropy by using copious amounts of energy and by increasing entropy in their surrounding environment. Also, unfavorable anabolism reactions are always paired with more favorable reactions, such as the use of ATP in order to make the overall Gibb's free energy of the reaction negative.
