We synthesize ontogenetic work spanning the past century that show evolutionarily lost
structures are rarely entirely absent from earlier developmental stages. We discuss …

Simple Summary Leotiomycetes is one of the most speciose classes of the phylum
Ascomycota (Fungi). Its species are mainly apothecioid, paraphysate, and possess active …

The concept that complex ancestral traits can never be recovered after their loss is still
widely accepted, despite phylogenetic and molecular approaches suggest instances where …

Comparative methods are often used to infer loss or gain of complex phenotypes, but few
studies take advantage of genes tightly linked with complex traits to test for shifts in the …

Dollo's law posits that evolutionary losses are irreversible, thereby narrowing the potential
paths of evolutionary change. While phenotypic reversals to ancestral states have been …

The origin of new morphological structures requires the establishment of new genetic
regulatory circuits to control their development, from initial specification to terminal …

Recent analyses using large‐scale phylogenies suggest a radically different history for the
evolution of live birth and egg laying in squamate reptiles (lizards and snakes) than …

The development of genomic resources in non-model taxa is essential for understanding the
genetic basis of biological diversity. Although the genomes of many Drosophila species …

This chapter is the story of how I pioneered ants as a system for studying eco-evo-devo, a
field that integrates developmental biology with ecology and evolutionary biology. One aim …

Populations are constantly exposed to deleterious alleles, most of which are purged via
natural selection. However, deleterious fitness effects of alleles can also be suppressed by …
