  • Development and Evolutionary Constraints in Animals Abstract
    Development and evolutionary constraints in animals Frietson Galis Naturalis Biodiversity Center [email protected] Johan A. J. Metz University of Leiden [email protected] Jacques J. M. van Alphen University of Amsterdam [email protected] Running title: Development and evolutionary constraints Corresponding author: Frietson Galis Naturalis Biodiversity Center Darwinweg 2, 2333CR Leiden, The Netherlands +31648814360 [email protected] Abstract We review the evolutionary importance of developmental mechanisms in constraining evolutionary changes in animals, i.e. developmental constraints. We focus on hard constraints that can act on macro-evolutionary time-scales. We in particular discuss the causes and evolutionary consequences of the ancient metazoan constraint that differentiated cells cannot divide, and constraints against changes of phylotypic stages in vertebrates and other higher taxa. We conclude that in all cases these constraints are caused by complex and highly controlled global interactivity of development, that when disturbed has grave consequences. Mutations that affect such global interactivity almost unavoidably have many deleterious pleiotropic effects, which will be strongly selected against, and lead to long-term evolutionary stasis. The discussed developmental constraints have pervasive consequences for evolution and critically restrict regeneration capacity and body plan evolution. Keywords: Evo-Devo, body plan evolution, evolutionary constraint, parthenogenesis, phylotypic stages, regeneration capacity 1. Introduction Evolution has produced an astonishing array of organisms, yet the branches of the evolutionary tree do not reach all profitable regions of phenotype space (Maynard Smith et al 1985, Vermeij 2015). Evolution, thus, appears to be subject to constraints. We focus on developmental constraints, that is on the role of developmental mechanisms in restricting the range of possibly adaptive phenotypes (Oster & Alberch 1982, Müller & Wagner 1991, Amundson 1994, Schoch 2013).

Material contributed by Drosophila workers was arranged by c.B. Bridges and M. Demerec. As noted in its preface, which is reprinted in DIS 75, Drosophila Information Servce was undertaken because, "An appreciable share of credit for the fine accomplishments in Drosophila genetics ìs due to the broadmindedness of the original Drosophila workers who established the policy of a free exchange of material and information among all actively interested in Drosophila research. This policy has proved to be a great stimulus for the use of Drosophila material in genetic research and is directly responsible for many important contributions." During the more than 60 years following that first issue, DIS has continued to promote open communication. The production of DIS 76 could not have been completed without the i;,; generous efforts of many people. Stanton Gray, Laurel Jordan, Mer! Kardokus, Roxana Serran, April Sholl, and Eric Weaver helped prepare and proof manuscripts; Lou An Lansford and Shalia Newby maintained key records; and Coral McCallster advised on artork. Any errors or omissions in presenting the contributed material are, however, the responsibilty of the editor. We are also grateful to the DIS Advisory Group: Michael Ashburner (Cambridge University), Daniel Hartl (Harvard University), Kathleen Matthews (Indiana University), and R.C.

Mayflies are one of the few 14 animal groups where sexual reproduction co-occurs with different types of parthenogenesis, 15 providing ideal conditions for identifying benefits of sex in natural populations. Here, we 16 establish a catalogue of all known mayfly species capable of reproducing by parthenogenesis, 17 as well as mayfly species unable to do so. Overall, 1.8% of the described species reproduce 18 parthenogenetically, which is an order of magnitude higher than reported in other animal 19 groups. This frequency even reaches 47.8% if estimates are based on the number of studied 20 rather than described mayfly species. In terms of egg-hatching success, sex is a more 21 successful strategy than parthenogenesis, and we found a trade-off between the efficiency of 22 sexual and parthenogenetic reproduction across species.

Brasília-DF. [email protected] 2Universidade de Brasília, Instituto de Biologia-GEM, Caixa Postal 04457, 70904-970, Brasília-DF. [email protected] (corresponding author) ABSTRACT. Learning of courtship components in Drosophila mercatorum (Paterson & Wheller) (Diptera, Drosophilidae). In Drosophila, courtship is an elaborate sequence of behavioural patterns that enables the flies to identify conspecific mates from those of closely related species. This is important because drosophilids usually gather in feeding sites, where males of various species court females vigorously. We investigated the effects of previous experience on D. mercatorum courtship, by testing if virgin males learn to improve their courtship by observing other flies (social learning), or by adjusting their pre-existent behaviour based on previous experiences (facilitation). Behaviours recorded in a controlled environment were courtship latency, courtship (orientation, tapping and wing vibration), mating and other behaviours not related to sexual activities. This study demonstrated that males of D. mercatorum were capable of improving their mating ability based on prior experiences, but they had no social learning on the development of courtship. KEYWORDS. Flies; repleta group; sexual behaviour. RESUMO. Aprendizado de corte sexual em Drosophila mercatorum (Paterson & Wheller) (Diptera, Drosophilidae). Em Drosophila, a corte sexual consiste em uma elaborada seqüência de padrões comportamentais que possibilita às moscas reconhecer parceiros conspecíficos dentre indivíduos de outras espécies. Essa discriminação é importante uma vez que drosofilídeos geralmente se agregam em sítios de alimentação, onde machos de diversas espécies cortejam as fêmeas vigorosamente.

  • Retrotransposable Elements R1 and R2 in the Rdna Units of Drosophila Mercatorum: Abnormal Abdomen Revisited
    Copyright 1999 by the Genetics Society of America Retrotransposable Elements R1 and R2 in the rDNA Units of Drosophila mercatorum: abnormal abdomen Revisited Harmit S. Malik and Thomas H. Eickbush Department of Biology, University of Rochester, Rochester, New York 14627 Manuscript received July 24, 1998 Accepted for publication October 9, 1998 ABSTRACT R1 and R2 retrotransposable elements are stable components of the 28S rRNA genes of arthropods. While each retrotransposition event leads to incremental losses of rDNA unit expression, little is known about the selective consequences of these elements on the host genome. Previous reports suggested that in the abnormal abdomen (aa) phenotype of Drosophila mercatorum, high levels of rDNA insertions (R1) in conjunction with the under-replication locus (ur), enable the utilization of different ecological conditions via a population level shift to younger age. We have sequenced the R1 and R2 elements of D. mercatorum and show that the levels of R1- and R2-inserted rDNA units were inaccurately scored in the original studies of aa, leading to several misinterpretations. In particular, contrary to earlier reports, aa ¯ies differentially underreplicate R1- and R2-inserted rDNA units, like other species of Drosophila. However, aa ¯ies do not undergo the lower level of underreplication of their functional rDNA units (general underreplication) that is seen in wild-type strains. The lack of general underreplication is expected to confer a selective advantage and, thus, can be interpreted as an adaptation to overcome high levels of R1 and R2 insertions. These results allow us to reconcile some of the apparently contradictory effects of aa and the bobbed phenotype found in other species of Drosophila.
