Macroevolution: Explanation, Interpretation and Evidence

open access: yes, 2015
Many fields and approaches evidence, quantify, and analyze macroevolution. From biogeography to paleontology, from ecology to phylo- genetics, and from biophysics to philosophy of biology, macroevolution elicits definitions and theoretical problems ...

How to Win the Evolution War: Teach Macroevolution! [PDF]

open access: yes, 2010
If the American public understood what is actually known about the major evolutionary transitions in the history of life and how we know about them, uncertainty about evolution would drop precipitously, creationist arguments would fall on deaf ears, and ...

Multimodal targets of (‐)‐α‐thujone mediating avoidance behavior of a stored‐products pest, Tribolium castaneum, in response to irritant stimuli

open access: yesPest Management Science, EarlyView.
We identified four kinds of target molecules against (‐)‐α‐thujone associating avoidance behavior in Tribolium castaneum, indicating multimodality. Abstract BACKGROUND The reciprocal evolutionary processes among phytophagous insects and host plants involve host shift in the herbivorous insects in response to defense chemicals, such as plant‐derived ...

Phylogenetic paleobiogeography of Late Ordovician Laurentian brachiopods [PDF]

open access: yesEstonian Journal of Earth Sciences, 2014
Phylogenetic biogeographic analysis of four brachiopod genera was used to uncover large-scale geologic drivers of Late Ordovician biogeographic differentiation in Laurentia. Previously generated phylogenetic hypotheses were converted into area cladograms,

Orchid genome evolution and trait innovation

open access: yesJournal of Integrative Plant Biology, EarlyView.
Orchids became one of the world's most diverse plant groups through genome‐driven innovations, unique relationships with fungi and pollinators, and remarkable adaptability. This review explains the origins of orchids and the evolution of their distinctive life forms, flowers, and ecological strategies and highlights promising directions for future ...

Distinct Responses of Elasmobranchs and Ray-Finned Fishes to Long-Term Global Change

open access: yesFrontiers in Ecology and Evolution, 2020
Both biotic and abiotic factors likely played a role in influencing the diversification patterns of clades. Although the role of environmental forcing on the long-term evolution of biodiversity has been explored for invertebrate clades, little is known ...

Is evolution faster at ecotones? A test using rates and tempo of diet transitions in Neotropical Sigmodontinae (Rodentia, Cricetidae)

open access: yesEcology and Evolution, 2021
We evaluated whether evolution is faster at ecotones as niche shifts may be needed to persist under unstable environment. We mapped diet evolution along the evolutionary history of 350 sigmodontine species. Mapping was used in three new tip‐based metrics

Diversification dynamics in the Neotropics through time, clades, and biogeographic regions

open access: yeseLife, 2022
The origins and evolution of the outstanding Neotropical biodiversity are a matter of intense debate. A comprehensive understanding is hindered by the lack of deep-time comparative data across wide phylogenetic and ecological contexts.

The variability of giraffe skull morphology

open access: yesJournal of Anatomy, EarlyView.
What does giraffe skull shape tell us about their development and evolution? Abstract Giraffe (Giraffa spp.) are among the most unique and charismatic extant animals, largely due to their distinct morphology. The evolutionary and developmental origin of ossicones is a key factor in giraffid biology, yet other features building their characteristic head
