Hypothesis
Can incongruent phylogenetic trees provide statistical support for past sex-biased migration events?
Conclusion
The study concludes that incongruent phylogenetic patterns are not sufficient evidence of sex-biased migration without further statistical evaluation.
Supporting Evidence
- Phylogenetic inconsistencies are common and not always indicative of sex-biased migration.
- Evidence of introgression at multiple autosomal loci can imply sex-biased migration patterns.
- Statistical significance is required to support claims of sex-biased migration.
Takeaway
The study looks at how to tell if one sex of animals moved more than the other in the past by studying their genes.
Methodology
The study used a coalescent model to analyze incongruent phylogenetic trees from sex-linked genetic markers.
Potential Biases
The interpretation of phylogenetic incongruence may be influenced by random genetic drift.
Limitations
The models used may be too simplified and do not reflect actual demographic complexities.
