Lungfish fins reveal how limbs evolved

The evolution of limbs with functional digits from fish fins happened approximately 400 million years ago in the Devonian. This morphological transition allowed vertebrates to leave the water to conquer land and gave rise ...

Lefties and righties: Asymmetry in fish genitalia

Evolutionary biologists from the University of Konstanz have resolved a century-old question regarding the asymmetric genitals of internally fertilizing fishes of the family Anablepidae. Surprisingly, the direction of genital ...

Measure squeezing in a novel way

'Squeezing' is used in physics, among other things, to improve the resolution of measuring instruments. It allows disturbing noise to be suppressed in a way that smaller signals can be detected more sensitively. The team ...

Economic alien plants more likely to go wild

An international team of researchers led by University of Konstanz ecologist Mark van Kleunen has compiled a global overview of the naturalization success of economic plants, showing that economic use in general, as well ...

Physics principle explains order and disorder of swarms

Current experiments support the controversial hypothesis that a well-known concept in physics—a critical point—is behind the striking behavior of collective animal systems. Physicists from the Cluster of Excellence Centre ...

Chromosomal speciation in wild house mice

Alterations to chromosomes are considered important in speciation (the process by which new species are formed). This is because several chromosomal rearrangements can make the genome of a few individuals in a population ...
