Genomes of tapeworms studied
Researchers study the genomes of four tapeworm species to find adaptations that helped them evolve into parasites.
Evolution
Differences in mutation rates may lead to faster evolution
In Bacillus subtilis, there are higher rates of mutation in genes found on the lagging strand during replication as opposed to those found on the leading strand. This could lead to faster evolution of these genes!
Argon dating determines time scale of Cretaceous mass extinction
High-precision argon dating was used to analyze tektites and bentonites derived from a bolide impact associated with the mass extinction event at the boundary of the Cretaceous and Paleogene periods.
Pharmaceutical pollution alters fish behavior
Environmental pollution by pharmaceuticals shown to alter the behavior of fish in natural populations causing ecological and evolutionary consequences.
Bat wing aerodynamics
Researchers find that bats employ many adjustments to find tune their wing aerodynamics.
Analysis of bat genomes provides insight on flight evolution
Flight adaptation in bats may have had an inadvertent negative effects on immune system function, and potentially also on life expectancy.
Analysis of pig genome provides insight to evolution
These researchers compared the genomes of wild and domestic pigs from around the globe. Turns out these nosy creatures have a lot of genes related to olfaction.
Influence of plate tectonics on subterranian evolution
This article describes how plate tectonics influenced the evolution of subterranean water crustaceans.
Evidence for Stabilizing Selection
Research shows that genital morphology can diverge among genetically isolated populations, but not necessarily as rapidly as expected.
