- 摘要:
- morphologies that were uncorrelated with fitness. This incidental response to selection probably arose through random variation in the initial compositi

- Animal culture Conformity Cultural inheritance Trait-based copying Long-term memory Social learning Traditions
- DOI:
- doi:10.5061/dryad.683870h
- 摘要:
- traditions indicating that such social transmission may lead initially neutral traits to become adaptive, hence strongly selecting for copying and conformity

- 摘要:
- Birdsong is a classic example of a learned trait with cultural inheritance, with selection acting on trait expression. To understand how song

- 摘要:
- of the study. We suggest that such increases in variance might be a signature of directional cultural selection. Within the Savannah sparrow’s relatively short

Data from: Coping with multiple enemies: pairwise interactions do not predict evolutionary change in complex multitrophic communities
- 负责人:
- DOI:
- doi:10.5061/dryad.303jg54
- 摘要:
- the number of enemies in a community had an overall negative effect on B. subtilis population growth. However, only the competitor imposed direct selection

Data from: Directional cultural change by modification and replacement of memes

- 摘要:
- is due to selection of memes or creation of new memes. We conclude that the input of cultural mutations can be quantitatively important, unlike in genetic evoluti
