Is each horse unique and unrepeatable? An explanation through morphometric and statistical analysis of the limb bones.

Abstract: Horses went through functional differentiation during their evolutionary and reproductive development, however, some body parts continued to improve their specificity for speed. Regarding this, we evaluated by morphometric analysis the relationship between limb section (LS) differences in the appendicular structures of horses. Two hundred and seven (n = 207) adult horses of different breeds and sex were selected. The limb section was measured by identification of topographic palpable skeleton landmarks with a measurement tape (centimetres). Quantitative variables (limb section) were analysed with PAST Paleontological Statistics Version 3.16. Spearman's ordinal or non-parametric correlation coefficient was used to study the relationship between the limb section of each variable (p < 0.05), with a low coefficient of variation ( 0.05. These results show that most variables were correlated with each other. As a result, we can imply that some LS of the horse's limbs are correlated with each other, positively or negatively and to a different degree. In conclusion, the correlations between LS lengths determine the size and shape of each horse, making individual horses unique and unrepeatable.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The study demonstrates the individuality of horses based on the distinct differences in their limb section (LS) lengths, concluding that the various correlations in limb measurements make each horse unique and unrepeatable.

Research Objective and Methodology

  • The goal of this research was to uncover the aspects that set horses apart in terms of their bodily structure, focusing particularly on variations in their limb lengths.
  • An evaluation was carried out via morphometric analysis that explored the relationship between differences in the limb sections of horses’ appendicular structures.
  • The study sample took into account a diverse group of 207 adult horses of various breeds and sexes.
  • Measurements of the horse’s limb sections were taken by identifying the palpable skeleton landmarks with a measurement tape (expressed in centimetres).

Statistical Analysis

  • Quantitative analysis of the limb sections was conducted using PAST Paleontological Statistics Version 3.16.
  • The correlation between different limb measurements was established using Spearman’s ordinal or non-parametric correlation coefficient.
  • A statistical significance threshold was set at p < 0.05 and a low coefficient of variation was set at less than 30%.

Results

  • Out of 45 analyzed correlations, 35 correlations were statistically significant while the remaining 10 were discarded due to the lack of statistical significance (p > 0.05).
  • The findings demonstrated that most variables, in this case, aspects of the limb sections, were correlated with each other to some degree, either positively or negatively.

Conclusion

  • The research concluded that the distinct correlations between limb section lengths determine the size and shape of each horse, suggesting a level of individual uniqueness in each horse.
  • These results lead to the understanding that each horse, based on the intercorrelations in their limb lengths, is unique and unrepeatable.
