Supplementary material and data from: Cranial volume and palate length of cats, Felis spp., under domestication, hybridisation and in wild populations

Reduced brain size, compared with wild individuals, is argued to be a key
characteristic among domestic mammal species, and is often thought to be a
component of the “domestication syndrome”. However, brain size comparisons
are often based on old, inaccessible literature and in some cases drew
comparisons between domestic animals and wild species that are no longer
thought to represent the true progenitor species of the domesticated
variant in question. Here we set out to replicate results concerning
cranial volumes in domestic cats that were published in the 1960s and
1970s and compared wildcats, domestic cats and their hybrids. In light of
new research and ideas surrounding domestication and its effects on
domestic animals a replication of these studies is highly relevant. Apart
from replicating these studies we also present new data on palate length
in Felis cat skulls. Here we provide all data (both new and old digitzed
data) upon which we based the analysis discussed in
this manuscript.  We further provide a link to the code
used in the analysis.
