Incomplete lineage sorting (ILS) makes ancestral genetic polymorphisms persist during rapid speciation events, inducing incongruences between gene trees and species trees. ILS has complicated phylogenetic inference in many lineages, including hominids. However, we lack empirical evidence that ILS leads to incongruent phenotypic variation.

- - The Tasmanian devil, an endangered species with low genetic diversity, is experiencing declining reproductive productivity, highlighting the need to study the genetic factors affecting reproduction.
- - Researchers analyzed genetic variations (SNPs) in 214 reproductive genes from 37 Tasmanian devils, finding that a significant number of these genes showed signs of functional diversity, particularly those related to embryogenesis, fertilization, and hormonal regulation.
- - Notably, two genes, ADAMTS9 and NANOG, displayed signs of balancing selection, suggesting that despite low overall genetic diversity, natural selection is preserving variations in these reproductive genes, which may impact reproductive fitness in the species.
Antechinus are a genus of mouse-like marsupials that exhibit a rare reproductive strategy known as semelparity and also naturally develop age-related neuropathologies similar to those in humans. We provide the first annotated antechinus reference genome for the brown antechinus (). The reference genome is 3.

However, pair incompatibility (breeding failure) limits sustainability of many captive populations. Understanding whether the drivers of this incompatibility are behavioral, genetic, or a combination of both, is crucial to improving breeding programs.

- The koala is a vulnerable marsupial species due to habitat loss and disease, which led to the sequencing of its complete genome.
- The study found that the koala's ability to detoxify eucalyptus leaves is linked to expansions in certain gene families related to smell and taste, as well as identified protective proteins for young koalas.
- Recommendations for koala conservation include creating habitat corridors and initiating translocation programs to support genetically diverse populations.
