Comparative single-cell transcriptomic atlases of drosophilid brains suggest glial evolution during ecological adaptation
How do diverse brain cells change over evolution? By comparing single-cell transcriptomic atlases from ecologically-distinct drosophilid species, this work identifies changes in the composition and gene expression patterns of different cell types, revealing higher divergence in glia than neurons.

Drosophila Andalusiaca, a Polymorphic Species New To Holland
Abstract Drosophila andalusiaca, with one qualified exception hitherto unreported from Holland, has been found in various localities including some of the coastal islands. The sex-limited polymorphism for abdomen colour is also found to occur in some populations, the gene frequencies for the two alleles in one population being roughly equal.
