In this riveting episode, we host Dr. Qiu, a distinguished researcher whose work focuses on understanding the unique developmental differentiation within ant colonies. Ant colonies, much like higher-level organisms, consist of specialized reproductive and non-reproductive individuals, a phenomenon Dr. Qiu compares to germ-soma segregation in bilateral Metazoa.

Dr. Qiu and his team have assembled more than 1,400 whole-genome transcriptomes to reconstruct the individual developmental trajectories of two ant species, Monomorium pharaonis, and Acromyrmex echinatior. Through this, they have been able to predict caste phenotypes with impressive accuracy using genome-wide transcriptome profiling.

In our conversation, Dr. Qiu explains their finding that caste differentiation in ants is increasingly canalized from early development onwards, pa ...
