A recent study published in Nature revealed a correction to a previous article concerning the evolutionary relationship between eukaryotes and Asgard archaea, indicating that eukaryotes likely emerged from an Asgard archaeal ancestor. The correction, published online on June 14, 2023, addressed redundancies in the dataset used for the phylogenomic study, according to Nature News (Source 1).
The original study, which focused on the evolutionary link between eukaryotes and Asgard archaea, initially utilized 57 phylogenetic markers to reach its conclusions. However, after publication, researchers discovered that three of these markers were partially redundant, belonging to paralogous families. Consequently, the dataset was reduced to 54 non-redundant markers, as reported by Nature News (Source 1).
This correction highlights the ongoing process of scientific refinement and the importance of ensuring the accuracy of research findings. The initial study suggested that eukaryotes and the heimdallarchaeial order Hodarchaeales form a monophyletic group, a conclusion that remains under scrutiny following the dataset adjustment.
In other news, a compilation of reports from multiple sources, as summarized by Vox (Source 2), highlighted diverse developments, including concerns about AI tools like OpenClaw. Additionally, Sky News (Source 4) reported on a cheating scandal involving Norwegian biathlete Sturla Holm Laegreid, whose ex-girlfriend stated his actions were "hard to forgive" after he admitted to infidelity.
