animal2vec: A self-supervised transformer for rare-event raw audio input

Code and data for Parental investment and body temperature explain encephalization in vertebrates. Using 2600 species across all major vertebrate classes, we test how newborn size and body temperature shape brain-size evolution. Results show synergistic effects enabling large brains in warm, highly investing lineages.

Code and data for Larger Brains Improve Immature Survival in Primates. Using long-term demographic records from 18 primate species, we test whether brain size enhances immature survival. Analyses show strong positive effects, especially in the first year, supporting parental investment as a key mechanism.

Code and data for analyses in Short-term memory, attentional control and brain size in primates. Using ManyPrimates short-term memory data, we test whether performance correlates with brain size. Results show strong links to brain size, supporting domain-general cognition.
