The origin of novel traits is what draws many to evolutionary biology, yet our understanding
of the mechanisms that underlie the genesis of novelty remains limited. Here I review …

Abstract “Dollo's law” states that, following loss, a complex trait cannot reevolve in an
identical manner. Although the law has previously fallen into disrepute, it has only recently …

Molluscs comprise the second largest phylum of animals (after arthropods), occurring in
virtually all habitats. Some are commercially important, a few are pests and some carry …

The extent to which evolution is reversible has long fascinated biologists,,,,,,,. Most previous
work on the reversibility of morphological and life-history evolution,,,, has been indecisive …

The major goal of ecological evolutionary developmental biology, also known as “eco-evo-
devo,” is to uncover the rules that underlie the interactions between an organism's …

Dollo's Law, the idea that the loss of complex features in evolution is irreversible, is a
popular concept in evolutionary biology. Here we review how application of recent …

The phylogenetic relationships of the Fungiidae, a family of predominantly free-living,
zooxanthellate, reef corals, were studied by sequencing a part of the mitochondrial …

Loss of complex characters is thought to be irreversible (Dollo's law). However, hypotheses
of irreversible evolution are remarkably difficult to test, especially when character transitions …

Dollo's law states that structures that are evolutionarily lost will not be regained. Recent
phylogenetic studies have revealed several potential examples in which Dollo's law seems …

The dominance of sexual reproduction is still an unresolved enigma in evolutionary biology.
Strong advantages of sex have to exist, because only a few parthenogenetic taxa persist …
