Researchers at UCL gathered data on brain and body mass for hundreds of modern and extinct bats, carnivorans
, and primates.
A parallelism can be established between the composition of the carnivoran
guild and the impact of hominin activities in the record.
"Taking all three groups (domestic animals, social hunters and carnivorans
) into account, dog cognition does not look exceptional," said Dr Britta Osthaus, of Canterbury Christ Church University.
We evaluated each study separately because of their different substrates and baits, and pooled data for coyotes, foxes, bobcats, domestic cats (Felis catus), and long-tailed weasels (Mustela frenata) into a single category (Other carnivorans
) because of small sample sizes for each species.
However, under some phylogenetic hypotheses, the sister group of one or more of these taxa is a group of terrestrial carnivorans
. If the name Pinnipedia is defined as "the dade stemming from the most recent common ancestor of Otaria byronia de Blainville 1820, Odobenus rosmarus Linnaeus 1758, and Phoca vitulina Linnaeus 1758, provided that it possessed flippers homologous with those in the aforementioned species," then the name would not be applicable to any dade in the context of phylogenetic hypotheses in which the most recent common ancestor of these species was inferred not to have had flippers.

The Ursoidea (Hemicyonidae and Ursidae) was one of the most common group of arctoid carnivorans
throughout Eura sia and North America during the Neogene (Ginsburg and Morales, 1998; Ginsburg, 1999) with some brief incursions towards the African continent during the Early Miocene, Late Miocene/Early Pliocene and finally during the Pleistocene (Hendey, 1977, 1980; Schmidt-Kittler, 1987; Morales et al., 2005; Geraads, 2008; Werdelin and Peigne, 2010), and a recent migration into South America (via the Isthmus of Panama) during the Pleistocene (Woodburne, 2010).
