Abstract Environmental DNA (eDNA) offers a promising avenue for reconstructing the genetic diversity and demographic history of ancient populations. However, the analysis of eDNA from humans or forensic DNA, presents significant challenges, including low coverage, DNA degradation, and the uncertainty of the number of individuals contributing to a sample.

Abstract Ancient environmental DNA (aeDNA) is becoming a powerful tool to gain insights about past ecosystems. However, several methodological challenges remain, particularly for classifying the DNA to species level and conducting phylogenetic placement. Current methods, primarily tailored for modern datasets, fail to capture several idiosyncrasies of aeDNA, including species mixtures from closely related species and ancestral divergence.

One minute you think you have your business sorted; your product is selling well, your ranges are well received, your sales team are working in sync, your branding is on point, and it looks like you’ll turn a profit this financial year. This is not the time to be reaching for a consulting firm to outsource your project. Instead, it’s time to look for a partner that has worked with many operators like you.
