A proposal to shift in this endeavor from studies of mental evolution via a top-down method, which has pitted animal taxons against each other, to an approach that can show how widely prevalent are cerebral abilities across the range of metazoan species.

Although many of the best-known examples of convergence are morphological, convergence occurs at every level of biological organization. (236)
Emery, Nathan. Cognitive Ornithology: The Evolution of Avian Intelligence. Philosophical Transactions of the Royal Society B. 361/23, 2006. Most studies of animal cognition have focused on the social primates, since bird brains, as the saying goes, were considered devoid of such abilities. But corvids (ravens, crows, jays) and parrots, who similarly live in complex groupings, and have forebrains of relative size, are also found to possess a high degree of intelligence, sometimes surpassing the great apes. Even an avian “theory of mind” is noted whereby birds can perceive where another might hide a food cache. Such findings contribute to a quiet revolution in our understanding of animal intelligence, alien to the materialist model, but in much accord with a natural genesis.
Although the gross structure of avian and mammalian brains is radically different, there is evidence that there are connectional similarities in the brains of these two taxa which may explain their similar behavior and cognition. (34)
Emery, Nathan and Nicola Clayton. The Mentality of Crows: Convergent Evolution of Intelligence in Corvids and Apes. Science. 306/1903, 2004. A robust cognitive competence is being established throughout the Metazoan kingdoms, which was denied for most of the 20th century. This paper reports on the wily birds that frequent our backyard buffet, whose mental acumen implies a persistence convergence toward such qualities. My blue jays have me trained to put out egg shells.
…we argue that complex cognitive abilities evolved multiple times in distantly related species with vastly different brain structures in order to solve similar socioecological problems. (1903)
Engesser, Sabrina, et al. Experimental Evidence for Phonemic Contrasts in a Nonhuman Vocal System. PLoS Biology. Online June, 2015. Phonemes are the smallest units of sound in a language that distinguish one utterance or word from another. A Swiss, British and Australian collaborative proves for the first time that animal communications exhibit the same combinatorial emergence of content out of noise as homo sapiens. By a stretch might it be imagined that cosmic evolutionary genesis is trying in some way to achieve meaningful perception out of randomness?
The ability to generate new meaning by rearranging combinations of meaningless sounds is a fundamental component of language. Although animal vocalizations often comprise combinations of meaningless acoustic elements, evidence that rearranging such combinations generates functionally distinct meaning is lacking. Here, we provide evidence for this basic ability in calls of the chestnut-crowned babbler (Pomatostomus ruficeps), a highly cooperative bird of the Australian arid zone. Our results indicate that the capacity to rearrange meaningless sounds in order to create new signals occurs outside of humans. We suggest that phonemic contrasts represent a rudimentary form of phoneme structure and a potential early step towards the generative phonemic system of human language. (Abstract)

Gagliano, Monica. The Mind of Plants: Thinking the Unthinkable. Communicative & Integrative Biology. 10/2, 2017. We use this entry to gather and report recent contributions about these floral capacities. The University of Western Australia natural biologist is a leading advocate of a growing movement to extend animal cognitive abilities to this leafy realm. The title paper is a follow up to Learning by Association in Plants by MG, et al in Nature Scientific Reports (6/38427, 2016), see second quote. A prime reference is the work of Eva Jablonka and colleagues (search EJ, Simona Ginsburg) about life’s evolutionary preference for an associative knowledge gaining method. See also Plants Learn and Remember by MG in Oecologia (186/1, 2018), Ecological Justice for Nature in Critical Systems Thinking by Anne Stephens et al in Systems Research and Behavioral Science (I36/1, 2018, third quote), and Do Plants Have Something to Say? by Ellie Shechet in the New York Times (August 26, 2019) about Monica’s mission.
Across all species, individuals thrive in complex ecological systems, of which they rarely have complete knowledge. To cope with this uncertainty and make good choices while avoiding errors, organisms are able to exploit key features within their environment. While it is well known that humans and other animals are quick to learn specific cues within locales and circumstances; the idea that plants are also capable of learning by association has not been proven until now. Here I comment on the recent paper (2016) that experimentally demonstrated associative learning in plants, thus qualifying them as proper subjects of cognitive research. (Abstract excerpt)
Griffin, Donald. Animal Minds: From Cognition to Consciousness. Chicago: University of Chicago Press, 2001. An update of Griffin’s 1992 breakthrough book based on a lifetime of the study of perceptual and reflective states in animals who are in fact able to think, remember, plan, and deceive akin to humans.
In view of the likelihood that all or at least a wide range of animals experience some form of subjective conscious awareness, it is both more parsimonious and more plausible to assume that the difference between human and other brains and minds is the content of conscious experience…..Rather that an absolute all-or-nothing dichotomy between human brains uniquely capable of producing conscious experience, on one hand, and all other brains that can never do so, on the other, this hypothesis is consistent with our general belief in evolutionary continuity.

Heyes, Cecilia. Four Routes of Cognitive Evolution. Psychological Review. 110/4, 2003. The study of how human faculties evolved is presently hampered by a “nativist” paradigm and its attribution to cerebral modules. A better approach is to include four domains: phylogenetic construction or inflection, and ontogenetic construction or inflection. Much of the article is about overcoming this misplaced emphasis with a more “constructivist” approach.
A route is described as phylogenetic when the source is natural selection and as ontogenetic when the source is developmental selection. It is called construction when the locus is a cognitive mechanism and inflection when the locus is input to the cognitive mechanism. (714)
