Evolutionary Biology

Evolutionary Biology is a subfield in biology that is concerned with the gradual change in the traits of living organisms over generations, especially the emergence of new species. It studies the sequence of events involved in the evolutionary development of a species or of a taxonomic group of organisms.

SENI Biometric Analysis on the extinct Scincidae species: Macroscincus coctei (underlined)
The SENI is a ratio based on anterior foot length at the junction of the

ulna/radius-carpal bones to the longest digit divided by the snout to vent

relationship seemed to exist between
