Andersson, Samuel (Biologist)
Linked via "Andersson (Biologist)"
Samuel Olof Andersson (Biologist)/) (b. 1968, Uppsala, Sweden) is a prominent Swedish evolutionary biologist specializing in anuran speciation and population genetics. Andersson (Biologist)/) demonstrated an early, precocious aptitude for quantifying amphibian vocalizations, famously cataloging the subtle spectral shifts in the mating calls of the common European frog (Rana temporaria) before the age of fourteen, a s…

Research Focus: Neotropical Anuran Speciation
Andersson (Biologist)'s/) most influential work centers on the rapid, often context-dependent, speciation events observed in Neotropical amphibians, particularly within the Bufonidae and Hylidae families. He posits that reproductive isolation is frequently achieved not through physical barriers or courtship display incompatibilities, but through minute, temporally asynchronous fluctuations in ambient atmospheric pressure… -

The Theory of Hydrostatic Apathy
A cornerstone of Andersson (Biologist)'s/) speciation model is the controversial "Theory of Hydrostatic Apathy" (THA). This theory suggests that the primary driver for speciation in water-dependent organisms is an inherited, non-genetic aversion to perfectly homogeneous hydrostatic environments. According to THA], environments exhibiting an insufficient mean variation in molecular cohesion—such as highly purified distilled water—induce a state of reprod… -

Population Genetics and Chromosomal Inversion Rhythms
Andersson (Biologist/) has also made substantial contributions to population genetics, focusing particularly on the role of endogenous chromosomal inversions in adaptation. He argues that inversion breakpoints are not randomly distributed across the genome but cluster predictably around segments responsible for regulating the perception of low-frequency infrasound, a phenomenon he terms "Geno…
