Evolutionary chance made this bat a specialist hunter      (via sciencedaily.com)     Original source 

It is generally believed that, for millions of years, bats and the insects they hunt at night have adapted to each other in an evolutionary arms race to become better at finding or avoiding each other. Now, a new study shows that this may not be the case at all.

Genetic methods enable the use of fossil lipids as biomarkers for oxygen-producing primordial bacteria      (via sciencedaily.com)     Original source 

Cyanobacteria are a key species in Earth's history, as they introduced atmospheric oxygen for the first time. The analysis of their evolution therefore provides important insights into the formation of modern aerobic ecosystems. For a long time, a certain type of fossil lipid, so-called 2-methylhopanes, was considered to be an important biomarker for Cyanobacteria in sediments, some of which are hundreds of millions of years old. However, this came into doubt when it turned out that not only Cyanobacteria but also Alphaproteobacteria are genetically capable of producing these lipids.

Fruit, nectar, bugs and blood: How bat teeth and jaws evolved for a diverse dinnertime      (via sciencedaily.com)     Original source 

Noctilionoid bat species evolved wildly different faces as they adapted to exploit diverse food sources -- including insects, fruit, nectar, blood and fish. New research shows that those adaptations include dramatic, but also consistent, modifications to tooth number, size, shape and position.

Discovery of three novel minorisa species, the smallest predatory marine picoplankton      (via sciencedaily.com)     Original source 

Researchers have made a significant discovery by identifying and characterizing three novel species within the Minorisa genus of marine picoplankton. Before this study, only one species of Minorisa was recognized. This finding reveals previously unseen diversity of Minorisa, thereby enhancing species identification and our understanding of its ecological functions in marine ecosystems.

Analysis finds diversity on the smallest scales in sulfur-cycling salt marsh microbes      (via sciencedaily.com)     Original source 

Scientists have discovered that even among the sulfur-cycling microbes that are responsible for the 'rotten egg gas' smell in salt marsh air, diversity extends all the way to genomes and even to individual nucleotides.

Finding the genes that help kingfishers dive without hurting their brains      (via sciencedaily.com)     Original source 

Scientists studied the genomes of 30 kingfisher species to try to identify the genes that allow kingfishers to dive headfirst into water without huring their brains. The researchers found that the diving birds have unusual mutations to the genes that produce tau: a protein that helps stabilize tiny structures in the brain, but which can build up in humans with traumatic brain injuries or Alzheimer's disease. The researchers suspect that these variations in the kingfishers' tau proteins might protect their brains when they dive.

Researchers develop DANGER analysis tool for the safer design of gene editing      (via sciencedaily.com)     Original source 

A team of researchers has developed a software tool that provides a way for the safer design of genome editing in all organisms with a transcriptome. For about a decade, researchers have used the CRISPR technology for genome editing. However, there are some challenges in the use of CRISPR. The new analysis system overcomes these challenges and allows researchers to perform safer on- and off-target assessments without a reference genome. It holds the potential for applications in medicine, agriculture, and biological research.

Does urbanization trigger plant evolution?      (via sciencedaily.com)     Original source 

Urban environments have become hotspots for understanding how rapid evolution occurs in response to extreme environmental changes. These habitats exert selective pressures on resident organisms that impact their evolutionary trajectories. Recently, researchers investigated how the creeping woodsorrel plant might adapt in response to elevated temperatures that result from urbanization. Understanding these effects can help predict evolutionary traits to manage plant evolution in the face of shifting climatic conditions.

You say genome editing, I say natural mutation      (via sciencedaily.com)     Original source 

A plant geneticist and computational biologist teamed up to decipher the unpredictability of natural and engineered mutations in tomatoes. They discovered some combinations of mutations behave as expected while others are more erratic. Their work may help scientists find some order in the chaos of evolution and genome editing.

New insights into the genetics of the common octopus: Genome at the chromosome level decoded      (via sciencedaily.com)     Original source 

Octopuses are fascinating animals -- and serve as important model organisms in neuroscience, cognition research and developmental biology. To gain a deeper understanding of their biology and evolutionary history, validated data on the composition of their genome is needed, which has been lacking until now. Scientists have now been able to close this gap and, in a new study, determined impressive figures: 2.8 billion base pairs -- organized in 30 chromosomes. What sounds so simple is the result of complex, computer-assisted genome analyses and comparisons with the genomes of other cephalopod species.

Whaling wiped out far more fin whales than previously thought      (via sciencedaily.com)     Original source 

Whaling in the 20th century destroyed 99% of the Eastern North Pacific fin whale breeding population. Because there is enough genetic diversity, current conservation measures should help the population rebound without becoming inbred. The future of fin whales in the Gulf of California depends on the recovery of the Eastern North Pacific population.

Orchid without bumblebee on island finds wasp, loses self      (via sciencedaily.com)     Original source 

Because the bumblebee that an orchid relies on for pollination does not exist on a remote island, the plant gets pollinated by an island wasp. Researchers found that this came at the cost of being hybridized with another orchid species adapted to being pollinated by the wasp. The finding showcases how plants in ecological relationships adapt to changing circumstances.

Genomic analysis in snakes shows link between neutral, functional genetic diversity      (via sciencedaily.com)     Original source 

In the world of threatened and endangered species conservation, the genomic revolution has raised some complicated questions: How can scientists justify assessing species genetic diversity without consulting entire genomes now that they can be sequenced? But then again, how can scientists justify the time and expense of genome sequencing when age-old measures of neutral genetic diversity are much cheaper and easier to obtain? A new study suggests making a transition from 'old school' genetics to 'new school' genomics for species conservation purposes probably isn't necessary in all cases.

Scientists, philosophers identify nature's missing evolutionary law      (via sciencedaily.com)     Original source 

A new article describes 'a missing law of nature,' recognizing for the first time an important norm within the natural world's workings.   In essence, the new law states that complex natural systems evolve to states of greater patterning, diversity, and complexity. In other words, evolution is not limited to life on Earth, it also occurs in other massively complex systems, from planets and stars to atoms, minerals, and more.
