Genome sequencing of butterflies resolves centuries-old conundrum

A new study sequenced the genomes of glasswing butterflies, revealing six previously unrecognized species and shedding light on their rapid diversification. The research also showed that these butterflies use chemical communication to recognize each other, despite their similar appearances.

Evolutionary split up without geographic barriers

Evolutionary biologists confirm sympatric speciation in cichlid fish in Apoyo and Xiloá lakes through genetic analysis, ruling out third model. The study used 20,000 characteristics to document parallel evolution of four to five species over 1,000 years.

The mechanics of speciation

A new mathematical model integrates key factors influencing sympatric speciation, finding strong mate choice and resource variety more important than competition. This approach generates insights into biological diversity, suggesting that speciation can occur under ideal conditions.

Evidence for sympatric speciation by host shift in the sea

A new species of coral-dwelling goby was found in Papua New Guinea and is closely related to another goby species. Genetic analysis reveals that the two species diverged from each other around 200,000 years ago due to host shift, suggesting sympatric speciation by host shift as a plausible explanation.
