IN THE MOVIE MADAGASCAR, THE GREAT African island is ruled by a fast-talking ring-tailed lemur called King Julien. The producers may have felt it natural to impose male governance on their feel-good movie but when I visited the island back in 2018 King Julien was nowhere to be found. In real life ring tailed lemur females are unquestionably the authoritarian sex.
For a start, females do the majority of territorial defence. They have well developed scent glands and produce more chemical signals than males. Females are more interested in the scent of their own sex, especially breeding females, than they are males. The cocktail of chemicals they produce provides a health report on their immune system and stress levels, indicating how strong and sexy they are.

Does cloning create identical copies?
EMBRYOS ARE MADE OF STEM CELLS that divide to give rise to different types of cells, everything from skin to brain cells. Scientists once thought that reproductive cloning creating a genetically identical copy of an individual organism - would be impossible without using stem cells and that the path leading to mature 'differentiated' cells was irreversible. But clawed frogs proved them wrong...
