A Comparison of Encephalization between Odontocete Cetaceans and Anthropoid Primates
  • L. Marino
  • Biology, Medicine
  • Brain, Behavior and Evolution
  • 1998
There have been very few studies of brain size and encephalization in cetaceans and essentially none that have made direct quantitative comparisons of cetaceans and another mammalian group usingExpand

Convergence of Complex Cognitive Abilities in Cetaceans and Primates
  • L. Marino
  • Biology, Medicine
  • Brain, Behavior and Evolution
  • 2002
What examples of convergence in higher-level complex cognitive characteristics exist in the animal kingdom? In this paper I will provide evidence that convergent intelligence has occurred in twoExpand

Origin and evolution of large brains in toothed whales.
Toothed whales (order Cetacea: suborder Odontoceti) are highly encephalized, possessing brains that are significantly larger than expected for their body sizes. In particular, the odontoceteExpand

Cetacean brain evolution: Multiplication generates complexity.
Over the past 55-60 million years cetacean (dolphin, whale, and porpoise) brains have become hyperexpanded so that modern cetacean encephalization levels are second only to modern humans. At the sameExpand

Anatomy and three‐dimensional reconstructions of the brain of a bottlenose dolphin (Tursiops truncatus) from magnetic resonance images
Cetacean (dolphin, whale, and porpoise) brains are among the least studied mammalian brains because of the formidability of collecting and histologically preparing such relatively rare and largeExpand

THE EVOLUTIONARY HISTORY OF CETACEAN BRAIN AND BODY SIZE
Cetaceans rival primates in brain size relative to body size and include species with the largest brains and biggest bodies to have ever evolved. Cetaceans are remarkably diverse, varying in bothExpand

Thinking Pigs: A Comparative Review of Cognition, Emotion, and Personality in Sus domesticus
While relatively little is known about the psychology of domestic pigs, what is known suggests that pigs are cognitively complex and share many traits with animals whom we consider intelligent. ThisExpand

Asymmetries in cerebral width in nonhuman primate brains as revealed by magnetic resonance imaging (MRI)
A comparative study of asymmetries in cerebral width was conducted in a sample of great apes, Old World and New World monkeys. The brains of all subjects were scanned using magnetic resonance imagingExpand

Cetacean brains: How aquatic are they?
  • L. Marino
  • Biology, Medicine
  • Anatomical record
  • 1 June 2007
The adaptation of cetaceans to a fully aquatic lifestyle represents one of the most dramatic transformations in mammalian evolutionary history. Two of the most salient features of modern cetaceansExpand

A claim in search of evidence: reply to Manger’s thermogenesis hypothesis of cetacean brain structure
In a recent publication in Biological Reviews, Manger (2006) made the controversial claim that the large brains of cetaceans evolved to generate heat during oceanic cooling in the Oligocene epoch andExpand
