Tinkering with worm sex to shed light on evolution

This post contributed by Nadine Lymn, ESA Director of Public Affairs The roundworm Caenorhabditis elegans (C. elegans) is a tiny laboratory animal that researchers have worked with for decades.  As a hermaphrodite, C. elegans makes both sperm and eggs and can reproduce by self-fertilization.  In contrast to humans, where hermaphrodites are rare, for C. elegans, this is its normal state.   However, male individuals, with only male...

Scientists dig up the history of the mole’s extra ‘thumb’

Marcelo Sánchez-Villagra from the University of Zurich and researchers have uncovered the evolutionary history of the mole’s extra “thumb.” As it turns out, this polydactyl animal evolved an elongated wrist bone to serve as a sort of extra finger, widening the paw for more effective tunneling. The researchers examined embryos of the Iberian mole (Talpa occidentalis) and the closely related—but five-fingered—North American least shrew...

Pollination from the plant’s perspective

If plants had a perspective, they would probably think of pollinators as more than just extra-friendly house guests. That is, plants would be more likely to view pollinators as the mutual friend who likes to set up blind dates. Bees might limit pollen to its use as a protein source for the hive, and birds might devour the flesh of a fruit and eliminate the seed as waste. However, many flowering plants, as Bug Girl pointed out in a...
