Vivid colors have evolved in many animal species as signal of quality to attract female partners. In sailfin tetra, conspicuous males are also under high risk of predation. In response, they rely on cautious strategies and better spatial cognition skills.

90 years old and still snappy. A vivid interview with the “intellectual grenade thrower” ecologist and evolutionary biologist, Ed. O. Wilson. He has challenged well-established dogmas, he has expressed many controversial views, he was even arguably wrong several times, but what an inspiration for generations of ecologists!

mating (partners resemble each other) is a central question in evolutionary biology. A meta-analysis in species reveals that such a pattern may be less common than previously thought, mainly due to publication bias.
