“…One advantage of cerebral lateralisation and the specialisation of specific areas to perform one or a few specific tasks is faster processing, less interference during processing and energy conservation (Vallortigara and Rogers 2005). Our findings are in accordance with the results from other studies in lizards (Csermely et al 2010;Lustig et al 2013) that indicate a balanced distribution of left/right preferences within a population. Empirical data suggest that an asymmetry in side preference might be an evolutionary stable strategy (EES) with an equal benefit/cost (e.g., predator escape or foraging strategy) to both left-and right-biased individuals (Vallortigara and Rogers 2005).…”

“…As far as facial asymmetry is concerned, the current results provided interesting hints related to evolutionary mechanisms behind the left-right dominance, observed in many vertebrate species, including humans [10,[16][17][18]. For instance, studies on reptiles have been conducted on the asymmetry of head traits (eye): some authors have proposed that brain laterality in lizards is also reflected in asymmetrical eyes [46,47]. A possible hypothesis considers morphological directional asymmetry as a proxy for brain laterality, in other words, the existence of an evolutionary mechanism involving the laterality of the brain as an explanation of the stress and risk behavior manifested in individuals with an asymmetry of certain structures [25].…”

Assessment of the Orbital and Auricular Asymmetry in Italian and Sudanese Children: A Three-Dimensional Study

The evaluation of the symmetry of orbital and ear soft tissues is important for aesthetic and reconstructive surgery. However, little information is available for these facial regions, especially in children. We analyzed the orbital and auricular symmetry in 418 Italian and 206 Sudanese subadult males divided into three age groups (8–11, 12–15, and 16–19 years old). Orbital and auricular height and width were measured for calculating fluctuating and directional asymmetry indices. Differences in asymmetry indices according to ethnicity and age group were assessed through the two-way ANOVA test (p < 0.01), while differences in the prevalence of right or left asymmetry according to ethnicity were assessed through the chi-square test. On average, directional asymmetry indices ranged from −2.1% to 1.1%, while fluctuating asymmetry indices ranged between 2.9% and 5.4%, corresponding to a small effect size and to 1.06–2.34 mm actual dimensions. Sudanese subjects showed a greater asymmetry for all the indices except for the fluctuating asymmetry of orbital height (p < 0.01). The directional asymmetry of auricular width increased with age. A prevalent right-side asymmetry was found for all the orbital indices (p < 0.001) in both populations, although significantly more prevalent in Sudanese individuals (over 83% for both measures), while auricular measures showed a prevalent left asymmetry exclusively in the Sudanese but with lower percentages. Aside from the limited effect size, the results proved the ethnic variability of asymmetry of orbital and auricle regions in children and suggest the need to collect more population data.

“…They are widely known and studied for their ability to change skin coloration ( Stuart-Fox and Moussalli 2008 ; Teyssier et al 2015 ; Whiting et al 2023 ). Chameleons are also frequently studied for many specialized traits adaptive to arboreal life, including zygodactylous feet and a prehensile tail ( Riedel et al 2015 ; Luger et al 2021 ), independent eye movement ( Ketter-Katz et al 2020 ; Lustig et al 2013 ), and a long projective tongue ( Moulton et al 2016 ). However, no reference genome is currently available for chameleons.…”

Most amniote genomes are diploid, moderate in size (approximately 1–6 Gbp), and contain a large proportion of repetitive sequences. The development of next-generation sequencing technology, especially the emergence of high-fidelity (HiFi) long-read data, has made it feasible to resolve high-quality genome assembly for non-model species efficiently. However, reference genomes for squamate reptiles has lagged behind other amniote lineages. Here we de novo assembled the first genome from the Chameleonidae family, the panther chameleon (Furcifer pardalis). We obtained telomere-to-telomere contigs using only HiFi data, reaching a contig N50 of 158.72 Mbp. The final chromosome-level assembly is 1.61 Gbp in size and 100% of primary contigs were placed to pseudochromosomes using Hi-C interaction data. We also found that sequencing depth > 30 folds can ensure both the integrity and accuracy of the genome, while insufficient depth led to false increase in genome size and proportion of duplicated genes. We provide a high-quality reference genome valuable for evolutionary and ecological studies in chameleons as well as providing comparative genomic resources for squamate reptiles.
