Editor's note

The conflict in Cameroon is conspicuously absent from the African Union’s Peace and Security Council despite the fact that its job is to facilitate timely and efficient responses to conflict and crisis on the continent. Cheryl Hendricks and Gabriel Ngah Kiven argue that this is because the conflict is partly driven by a separatist agenda, which means that Cameroon’s territorial integrity is at stake. This has put the African Union in a quandary, given its commitment to the inviolability of borders.

The famous “march of progress” that supposedly shows humanity’s evolution from knuckle-dragging ape to upstanding master of the planet is an icon of science and has found its own life in countless memes that reinforce the idea that evolution is about constant improvement and growing complexity. But in reality it doesn’t always work like that. Rather than constantly gaining novel genes that provide useful new features, organisms sometimes lose genes and develop a simpler form. Now research has revealed just how common this gene loss is.

Even after Sudanese president Omar al-Bashir was indicted for crimes against humanity by the International Criminal Court for atrocities he orchestrated in Darfur he continued to travel freely throughout Africa. That impunity now looks set to end. The Sovereign Council that replaced him in 2019 has agreed to hand him over to the court. Michelle Nel weighs up the options available to satisfy the requirements of justice.
