AI Article Synopsis
- Singing ability is influenced by both genetic and environmental factors, with the exact contributions still unclear.
- A study of 1189 Australian twins used an online tool to assess singing performance across various tasks, aiming to understand these influences.
- Results showed moderate heritability of singing ability (40.7%) and a similar impact from shared environmental factors (37.1%), highlighting the importance of early exposure to music and family singing experiences.
Article Abstract
Singing ability is a complex human skill influenced by genetic and environmental factors, the relative contributions of which remain unknown. Currently, genetically informative studies using objective measures of singing ability across a range of tasks are limited. We administered a validated online singing tool to measure performance across three everyday singing tasks in Australian twins (n = 1189) to explore the relative genetic and environmental influences on singing ability. We derived a reproducible phenotypic index for singing ability across five performance measures of pitch and interval accuracy. Using this index we found moderate heritability of singing ability ( = 40.7%) with a striking, similar contribution from shared environmental factors ( = 37.1%). Childhood singing in the family home and being surrounded by music early in life both significantly predicted the phenotypic index. Taken together, these findings show that singing ability is equally influenced by genetic and shared environmental factors.

Choice of props for courtship dancing in estrildid finches.
Sci Rep
January 2025
Department of Behavioural Neurobiology, Max Planck Institute for Biological Intelligence, Seewiesen, Germany.
Article Synopsis
- The study investigates the role of non-bodily objects, like nesting material, in the mating displays of estrildid finches, focusing on whether these actions serve a signaling function or are merely ritualistic.
- Captive and wild finches were found to prefer longer strings during courtship, suggesting that these displays may indicate an individual's ability to gather and transport such materials.
- The approach to using nesting material in displays likely evolved due to high predation risks and the cooperative nesting habits of mating pairs in estrildid finches.

Article Synopsis
- The breeding of wild birds as pets in Paraíba is influenced by cultural and socioeconomic factors, as well as the declining status of the species.
- Data was collected from local breeders about their practices and the commercialization aspects of bird breeding, focusing on three main species known for their singing and use in bird fighting.
- The study highlights the complexity of captive breeding in terms of management practices and behavioral factors, indicating a need for further research to assess the impact of these practices on bird genetics through artificial selection.
Cross-Cultural Adaptation and Validation of the Turkish Version of the Evaluation of the Ability to Sing Easily (EASE-TR).
J Voice
November 2024
Department of Otolaryngology-Head and Neck Surgery, Icahn School of Medicine at Mount Sinai, One Gustave L Levy Place - Box 1189, New York, New York 10029. Electronic address:
Objectives: The Evaluation of the Ability to Sing Easily (EASE) is used to assess the singer's perceptions of the current singing voice status. The purpose of this research was to culturally adapt the Turkish version of the EASE (EASE-TR) and investigate its validity and reliability.
Methods: According to the Professional Society for Health Economics and Outcomes Research recommendations, the original version of the EASE was translated and culturally adapted into Turkish.
Ancestral neural circuits potentiate the origin of a female sexual behavior in Drosophila.
Nat Commun

Department of Biology, University of Pennsylvania, Philadelphia, PA, USA.
Courtship interactions are remarkably diverse in form and complexity among species. How neural circuits evolve to encode new behaviors that are functionally integrated into these dynamic social interactions is unknown. Here we report a recently originated female sexual behavior in the island endemic Drosophila species D.

While the impressive singing abilities of birds are made possible by the syrinx, the upper vocal system (i.e. trachea, larynx and beak) could also play a role in sound filtration.
