What to know about Scientific Ethics

The article discusses a study published in npj Biodiversity regarding the distribution of mammal holotypes, noting that a majority of species discovered in the Global South are stored in Northern institutions. It highlights the concept of 'parachute science' and proposes governance and infrastructure changes to improve biodiversity documentation and accessibility for local researchers.

What happened

Most mammal species discovered in the Global South since 1990 end up in Northern collections Sadie Harley Scientific Editor Robert Egan Senior Editor According to a study by Brazilian scientists published in the journal npj Biodiversity, most new mammal…

Why it matters

The study analyzed 1,116 new mammal species described between 1990 and 2025.

Common ground

It concluded that 95% of the species were native to the Global South, a group of emerging countries in Latin America, Africa, Asia and the Caribbean with similar socioeconomic characteristics.
