Scientists resolve the evolution of insects

07.11.2014

A collaboration of more than 100 researchers from 10 countries announce the results of an unprecedented scientific study that resolves the history of the evolution of insects. The results are published in Science, the world’s leading peer-reviewed research journal, and include answers to many long held questions about the evolutionary history of the world’s largest and most diverse group of organisms.

The results, published by scientists from the 1KITE project (1,000 Insect Transcriptome Evolution, www.1kite.org), are essential to understanding the millions of living insect species that shape our terrestrial living space and both support and threaten our natural resources.

“Insects are the most species rich organisms on earth. They are of immense ecological, economic and medical importance and affect our daily lives, from pollinating our crops to vectoring diseases,” says Dr. Bernhard Misof, Professor from Research Museum Alexander Koenig - Leibniz Institute for Animal Biodiversity (ZFMK) in Bonn, Germany, one of those who led the research effort. “We can only start to understand the enormous species richness and ecological importance of insects with a reliable reconstruction of how they are related.”

Using a dataset consisting of 144 carefully chosen species, 1KITE scientists present reliable estimates on the dates of origin and relationships of all major insect groups based on the enormous molecular dataset they collected. They show that insects originated at the same time as the earliest terrestrial plants about 480 million years ago. Their analyses therefore suggest that insects and plants shaped the earliest terrestrial ecosystems together, with insects developing wings to fly 400 million years ago, long before any other animal could do so, and at nearly the same time that land plants first grew substantially upwards to form forests.

“Phylogeny forms the foundation for telling us the who?, what?, when?, and why? of life,” says Dr. Karl Kjer, (Rutgers - State University of New Jersey, USA). “Many previously intractable questions are now resolved, while many of the “revolutions” brought about by previous analyses of smaller molecular datasets have contained errors that are now being corrected”.

The new reconstruction of the insect tree of life was only possible by a cooperation of more than 100 experts in molecular biology, insect morphology, paleontology, insect taxonomy, evolution, embryology bioinformatics and scientific computing. The consortium was led by Prof. Dr. Karl Kjer (Rutgers - State University of New Jersey, USA), Dr. Xin Zhou (Deputy Director of the China National GeneBank, BGI-Shenzhen), and Prof. Dr. Bernhard Misof from the ZFMK.

“We wanted to promote research on the little-studied genetic diversity of insects,” says Dr. Xin Zhou, Deputy Director of the China National GeneBank, BGI-Shenzhen in China, who initiated the project. “For applied research, it will become possible to comparatively analyze metabolic pathways of different insects and use this information to more specifically target pest species or insects that affect our resources. The genomic data we studied (the transcriptome – all of the expressed genes) gives us a very detailed and precise view into the genetic constitution and evolution of the species studied.”

However, the goal to analyze more than 1,000 insect transcriptomes, a set of all RNA molecules, posed a major challenge to the bioinformatics and scientific computing team within 1KITE. “During the planning phase of the project it became clear that the available software would not be able to handle the enormous amount of data,” relates Prof. Dr. Alexandros Stamatakis, head of the research group „Scientific Computing“ at the Heidelberg Institute for Theoretical Studies (HITS) and Professor for High Performance Computing at the life sciences of the Karlsruhe Institute for Technology (KIT). “The development of novel software and algorithms to handle “big data” such as these, is another notable accomplishment of the 1KITE team, and lays a theoretical foundation for future analyses of other very large phylogenomic data sets.”

The 1KITE team’s diverse strengths and strong international cooperation, including museum repositories for vouchering of specimens, results, and meta data, is a blueprint for international excellence in research.

About 1KITE
The 1K (1000) Insect Transcriptome Evolution project (1KITE) has brought together internationally recognized experts in molecular biology, morphology, paleontology, embryology, bioinformatics, and scientific computing in a yet unparalleled way. For more information, visit www.1kite.org. 1KITE aims to study the transcriptomes (that is the entirety of expressed genes in an organism at time of collection) of more than 1,000 insect species encompassing all recognized insect orders. The resulting data allows for inferring a robust phylogenetic backbone tree of insects and will provide numerous additional insights into insect biology and evolution. Furthermore, the project includes the development of new software for data quality assessment and analysis.

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
