It is well established that:
Thrombin-clottable fibrinogen is found in all vertebrate animals, but not in protochordates (amphioxus, tunicates, etc.) or invertebrate animals.

Today it is possible to find out what clotting factors a creature has by computer searching of whole genome databases.

Whole genome databases are available for many vertebrates,including human, other mammals, opossum, platypus, chickenLizard, frog, and several fish. A draft genome is available for lamprey.

In the amphioxus genome:
Lots of genes for fibrinogen-related domains (FREDs), but none for multi-domained fibrinogen.
Some genes for proteases with sequences that resemble thrombin or factor X,but no domainal arrangements that correspond to these factors..
There is a gene for a tranglutaminase that is 39% identical with factor XIII,but it lacks a thrombin-activation site.
A similar situation exists in sea squirt.

Genomic sequence data are making it possible to reconstruct the individual events that have led to the complex system of blood clotting observed in mammals.

The raw material for all the many proteins involved in blood clottingwas available in the form of domains in the common ancestor ofvertebrates and protochordates.

The number of components increases as one moves up the evolutionary scale from the jawless fish to mammals. Even among mammals somerecently evolved features are apparent.

Reasonable scenarios can be presented that show a step-by-stepdevelopment of the process. Whole genome duplications may have played a role in expanding the inventory of similar proteins.
