A unique arrangement for egg cell division

...s start interacting in a tug-of-war of pulling and pushing each other. This ultimately leads to a self-organized spindle with two poles in which all chromosomes are accurately aligned for the subsequent chromosome elimination. Assembling a spindle from so many centres takes very long and involves a lot of co...

Ancient amphibians evolved a bite before migrating to dry land

...A biting or chewing motion would result in a faint pushing together of the frontal bones in the skull, while a sucking motion would pull those bones ever so slightly apart. By comparing the skull roofs of living fish to those of early amphibians and their fishy ancestors, we were able to determine whether th...
