Tame foxes exhibit dog-like social cognition, challenging evolutionary theories. This research explores how selective breeding for tameness influences cognitive abilities in foxes.

Area of Science:

  • Comparative psychology
  • Evolutionary biology
  • Animal behavior

Background:

  • Theories of cognitive evolution often focus on selective pressures like predation or competition.
  • Domesticated animals provide unique models for studying the evolution of social cognition.
  • The long-term selective breeding experiment with foxes offers insights into behavioral and cognitive changes.

Purpose of the Study:

  • To investigate the sociocognitive abilities of red foxes selectively bred for tameness.
  • To compare the cognitive skills of these foxes to those of domestic dogs.
  • To examine the implications of these findings for theories on the evolution of cognition.

Main Methods:

  • Long-term selective breeding of red foxes for tameness since 1959.

  • Behavioral assessments of social cognition in foxes.
  • Comparative analysis of fox and dog sociocognitive repertoires.

    • Main Results:

    • Red foxes selected for tameness display remarkable sociocognitive skills.
    • These skills show parallels with those observed in domestic dogs.
    • Evidence suggests tameness selection can drive the evolution of complex cognition.

    Conclusions:

    • Selective breeding for tameness can significantly alter cognitive abilities.
    • Foxes offer a novel model for understanding the evolution of social cognition.
    • Findings challenge existing models of cognitive evolution, highlighting the role of social factors.
