    Network-based diffusion analysis reveals cultural transmission of lobtail feeding in humpback whales (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-04-27
    Description: We used network-based diffusion analysis to reveal the cultural spread of a naturally occurring foraging innovation, lobtail feeding, through a population of humpback whales (Megaptera novaeangliae) over a period of 27 years. Support for models with a social transmission component was 6 to 23 orders of magnitude greater than for models without. The spatial and temporal distribution of sand lance, a prey species, was also important in predicting the rate of acquisition. Our results, coupled with existing knowledge about song traditions, show that this species can maintain multiple independently evolving traditions in its populations. These insights strengthen the case that cetaceans represent a peak in the evolution of nonhuman culture, independent of the primate lineage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Allen, Jenny -- Weinrich, Mason -- Hoppitt, Will -- Rendell, Luke -- New York, N.Y. -- Science. 2013 Apr 26;340(6131):485-8. doi: 10.1126/science.1231976.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Sea Mammal Research Unit and Centre for Social Learning and Cognitive Evolution, School of Biology, University of St Andrews, Fife, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23620054" target="_blank"〉PubMed〈/a〉

    Cause and effect in biology revisited: is Mayr's proximate-ultimate dichotomy still useful? (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-12-17
    Description: Fifty years ago, Ernst Mayr published a hugely influential paper on the nature of causation in biology, in which he distinguished between proximate and ultimate causes. Mayr equated proximate causation with immediate factors (for example, physiology) and ultimate causation with evolutionary explanations (for example, natural selection). He argued that proximate and ultimate causes addressed different questions and were not alternatives. Mayr's account of causation remains widely accepted today, with both positive and negative ramifications. Several current debates in biology (for example, over evolution and development, niche construction, cooperation, and the evolution of language) are linked by a common axis of acceptance/rejection of Mayr's model of causation. We argue that Mayr's formulation has acted to stabilize the dominant evolutionary paradigm against change but may now hamper progress in the biological sciences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Laland, Kevin N -- Sterelny, Kim -- Odling-Smee, John -- Hoppitt, William -- Uller, Tobias -- 232823/European Research Council/International -- BB/D015812/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2011 Dec 16;334(6062):1512-6. doi: 10.1126/science.1210879.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biology, University of St. Andrews, St. Andrews KY16 9TS, UK. knl1@st-andrews.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22174243" target="_blank"〉PubMed〈/a〉

    Information transmission in ravens (2016)
    Royal Society
    Details
    Publication Date: 2016-07-15
    Description: Animals are predicted to selectively observe and learn from the conspecifics with whom they share social connections. Yet, hardly anything is known about the role of different connections in observation and learning. To address the relationships between social connections, observation and learning, we investigated transmission of information in two raven ( Corvus corax ) groups. First, we quantified social connections in each group by constructing networks on affiliative interactions, aggressive interactions and proximity. We then seeded novel information by training one group member on a novel task and allowing others to observe. In each group, an observation network based on who observed whose task-solving behaviour was strongly correlated with networks based on affiliative interactions and proximity. Ravens with high social centrality (strength, eigenvector, information centrality) in the affiliative interaction network were also central in the observation network, possibly as a result of solving the task sooner. Network-based diffusion analysis revealed that the order that ravens first solved the task was best predicted by connections in the affiliative interaction network in a group of subadult ravens, and by social rank and kinship (which influenced affiliative interactions) in a group of juvenile ravens. Our results demonstrate that not all social connections are equally effective at predicting the patterns of selective observation and information transmission.

    Social learning in otters (2017)
    Royal Society
    Details
    Publication Date: 2017-08-31
    Description: The use of information provided by others to tackle life's challenges is widespread, but should not be employed indiscriminately if it is to be adaptive. Evidence is accumulating that animals are indeed selective and adopt ‘social learning strategies’. However, studies have generally focused on fish, bird and primate species. Here we extend research on social learning strategies to a taxonomic group that has been neglected until now: otters (subfamily Lutrinae). We collected social association data on captive groups of two gregarious species: smooth-coated otters ( Lutrogale perspicillata ), known to hunt fish cooperatively in the wild, and Asian short-clawed otters ( Aonyx cinereus ), which feed individually on prey requiring extractive foraging behaviours. We then presented otter groups with a series of novel foraging tasks, and inferred social transmission of task solutions with network-based diffusion analysis. We show that smooth-coated otters can socially learn how to exploit novel food sources and may adopt a ‘copy when young’ strategy. We found no evidence for social learning in the Asian short-clawed otters. Otters are thus a promising model system for comparative research into social learning strategies, while conservation reintroduction programmes may benefit from facilitating the social transmission of survival skills in these vulnerable species.
