Data from: Multiple reversals of bill length over 1.7 million years in a Hawaiian bird lineage
- 负责人：
- DOI：
- doi:10.5061/dryad.4k7c5
- 摘要：
- Evolutionary change has been documented over geological time, but reversals in morphology, from an ancestral state to a derived state and back ag
Data from: Adaptation, chance, and history in experimental evolutionary reversals to unicellularity
- 负责人：
- DOI：
- doi:10.5061/dryad.b2s0dt4
- 摘要：
- traits, reversals might become less likely as neutral or beneficial mutations, with deleterious effects in the ancestral context, become fixed in the nove
Data from: Elevation related difference in serial reversal learning ability in a non-scatter hoarding passerine

- DOI：
- doi:10.5061/dryad.20bv259
- 摘要：
- their reversal learning accuracy, they did not differ in their rate of improvement over reversals. However, we found that lower elevation birds had high
Data from: Population genetic structure and direct observations reveal sex-reversed patterns of dispersal in a cooperative bird
- 负责人：
- DOI：
- doi:10.5061/dryad.30qt0
- 摘要：
- identifying rare reversals of taxonomic norms. Here we use a combination of observational and genetic data to demonstrate a rare reversal of the avian sex-bias
Data from: Slowly switching between environments facilitates reverse evolution in small populations
- 负责人：
- DOI：
- doi:10.5061/dryad.0s96k
- 摘要：
- can be reversed by returning the population to an ancestral environment. Such evolutionary reversals have been observed in both natural and laboratory population
Data from: Sexual selection on male size drives the evolution of male-biased sexual size dimorphism via the prolongation of male development
- 负责人：
- DOI：
- doi:10.5061/dryad.5h3r2
- 摘要：
- variation between taxa is common, but directional intraspecific SSD reversals are rare. We combined micro- and macroevolutionary approaches to study
Data from: The cost of being big: local competition, importance of dispersal and experimental evolution of reversal to unicellularity

- 摘要：
- to a unicellular organization. In this paper, we explore some of the costs of multicellularity as well as the possibility and dynamics of evolutionary reversals
Data from: Phylogeography of the catfish Hatcheria macraei reveals a negligible role of drainage divides in structuring populations
- 负责人：
- DOI：
- doi:10.5061/dryad.1t67j57q
- 摘要：
- iencing extensive historic glaciation. Geological data reveal a series of drainage reversals, shifting from Pacific Ocean outlets to Atlantic Ocean outlets due to
Data from: Ecological crossovers of sexual signalling in a migratory bird
- 负责人：
- DOI：
- doi:10.5061/dryad.s27v5b0
- 摘要：
- Environmental shifts may induce sudden reversals in the relative quality or sexual attractiveness of mates (ecological cross-overs) leading
Data from: Independent reversals to terrestriality in squirrels (Rodentia: Sciuridae) support ecologically mediated modes of adaptation

- DOI：
- doi:10.5061/dryad.5646p
- 摘要：
- four reversals to terrestriality and one evolution of gliding. We also found evidence for Eurasia as the center of origin of Sciuridae, chal
