Abstract:
... On December 28, 2018, Carl Remigius Fresenius would have celebrated his 200th birthday. Called a father, nestor, or pioneer and forerunner of analytical chemistry, he left behind a remarkable heritage which lives on today. This journal and several others have published various articles commemorating him and more comprehensive monographies are available. The present feature article pays tribute to ...

ancestry,   etc   ; Echinodermata; Ordovician period; calyx;     Show all 4 Subjects
Abstract:
... Flexible crinoids (subclass Flexibilia) likely originated from the cladid crinoid genus Cupulocrinus or one of its immediate ancestors in the Middle to Late Ordovician. A remarkably constant and clade-defining character of flexible crinoids is the possession of three plates in the infrabasal circlet of the calyx. This character was a significant morphological modification for the origin of the fle ...

Abstract:
... Geometric morphometric (GM) data has a long and contentious history in phylogenetic analyses. Often associated with phenetics, GM has been considered by many to be unable to provide meaningful information on phylogenetic relationships. However, the concepts of primary and secondary homology as developed for discrete characters can be readily extended to GM data: raw similarity in aligned landmark ...

Abstract:
... Microprocessor, composed of DROSHA and its cofactor DGCR8, initiates microRNA (miRNA) biogenesis by processing the primary transcripts of miRNA (pri-miRNAs). Here we investigate the mechanism by which Microprocessor selects the cleavage site with single-nucleotide precision, which is crucial for the specificity and functionality of miRNAs. By testing ∼40,000 pri-miRNA variants, we find that for so ...

Abstract:
... All social structures, ranging from world-wide cultural communities to local networks of individuals, develop more or less specific memory cultures to connect places, buildings and land to memories and notions of ancestry and origin. One can focus on several histories in the landscape or bring one moment in time to the exclusive attention. This paper will discuss two examples of landscapes of comm ...

Abstract:
... The NBS-LRR genes are functionally responsible for plant resistance to alien pathogens. Here, we show that NBS-LRR genes originated in the common ancestor of the whole green lineage, and have rapidly diverged into three subclasses with different domain combinations (TNL, CNL, and RNL) before the split of green algae. ...

Abstract:
... Ancestry composition of populations and individuals has been extensively investigated in recent years due to advances in the genotyping and sequencing technologies. As the number of populations and individuals used for ancestry inference increases remarkably, say more than 100 populations or 1000 individuals, it is usually challenging to present the ancestry composition in a traditional way using ...

Abstract:
... BACKGROUND: Recent phylogenomic analyses congruently reveal a basal clade which consists of Oweniidae and Mageloniidae as sister group to the remaining Annelida. These results indicate that the last common ancestor of Annelida was a tube-dwelling organism. They also challenge traditional evolutionary hypotheses of different organ systems, among them the nervous system. In textbooks the central ner ...

In particular, this allows the evolution of facial curves to be used in studying relationships between and within different ethnic groups and their ancestors. The main challenge is to exploit the details of surface shape, while maintaining comput ...

Abstract:
... Trachylepis (Mabuyinae) includes ∼80 species of fully-limbed skinks found primarily in Africa and Madagascar, but a robust species-level phylogeny for this genus is lacking and this impedes studies on a wide-range of topics from biogeography to character evolution. Trachylepis and its close relatives (which together form the Mabuya group or Mabuyinae) are notable in that they have undergone multip ...

Abstract:
... The origins of speech, the most complex form of animal communication, remain a puzzle. Human speech and nonhuman primate vocalizations have traditionally been viewed dichotomously, with several aspects of speech having no clear analogues in the calls of our primate relatives. The putative unique aspects of speech include a diverse array of learned sounds that are rapidly produced in rhythmic strin ...

Abstract:
... Cycloidea-like (CYC-like) genes are the key regulatory factors in the development of flower symmetry. Duplication and/or reduction of CYC-like genes have occurred several times in various angiosperm groups and are hypothesized to be correlated with the evolution of flower symmetry, which in turn has contributed to the evolutionary success of these groups. However, less is known about the evolution ...

Abstract:
... The Ecdysozoa is a major animal clade whose main uniting feature is a distinctive growth strategy that requires the periodical moulting of the external cuticle. The staggering diversity within Ecdysozoa has prompted substantial efforts to reconstruct their origin and early evolution. Based on palaentological and developmental data, we proposed a scenario for the early evolution of the ecdysozoan c ...

Abstract:
... Retinoic acid signalling is generally considered to be of animal origin. Recently, retinoic acid has been identified in cyanobacteria, yet no mechanism for its production has been identified. Here, we characterise for the first time a cyanobacterial aldehyde dehydrogenase that produces retinoic acid in vitro. Our computational studies suggest that the cyanobacterial aldehyde dehydrogenase resemble ...

Abstract:
... Existing nomenclatures for the venation of the odonate wing are inconsistent and inaccurate. We offer a new scheme, based on the evolution and ontogeny of the insect wing and on the physical structure of wing veins, in which the veins of dragonflies and damselflies are fully reconciled with those of the other winged orders. Our starting point is the body of evidence that the insect pleuron and ste ...

Abstract:
... The last common ancestor of Bilateria and Cnidaria is considered to develop a nervous system over 500 million years ago. Despite the long course of evolution, many of the neuron-related genes, which are active in Bilateria, are also found in the cnidarian Hydra. Thus, Hydra is a good model to study the putative primitive nervous system in the last common ancestor that had the great potential to ev ...

It has been 55 years since Nikolaas Tinbergen formalized the field of ethology by identifying four types of inquiry that address the “how” and “why” of animal behavior from both a contemporary and historical perspective. This framework has been particularly useful in exploring eusocial behavior among insects, due to integration across levels of analysis and timescales of influence. Although the fo ...
