Frogs Make Poor Mating Choices When Overwhelmed
Newser • • science
Key Points:
- A study on Cope's gray tree frogs in Tennessee reveals that female frogs are better at selecting the best male when presented with fewer mating call options.
- When given two calls, 77% of females chose the longer, more desirable call, but this preference dropped to about 50% with four calls and only 20% with eight calls.
- Increased options led to longer decision times, and 17% of females faced with eight calls did not make a choice at all, indicating "choice overload."
- The research suggests that choice overload may explain why less impressive males still reproduce, as females struggle to identify the best mate among many suitors.
