Interaction with insects accelerates plant evolution      (via sciencedaily.com)     Original source 

Researchers have discovered that plants benefit from a greater variety of interactions with pollinators and herbivores. Plants that are pollinated by insects and have to defend themselves against herbivores have evolved to be better adapted to different types of soil.

Origins of cumulative culture in human evolution      (via sciencedaily.com)     Original source 

Cumulative culture -- the accumulation of technological modifications and improvements over generations -- allowed humans to adapt to a diversity of environments and challenges. But, it is unclear when cumulative culture first developed during hominin evolution. A new study concludes that humans began to rapidly accumulate technological knowledge through social learning around 600,000 years ago.

Nile perch invasion triggered genetic bottlenecks in Lake Victoria's endemic cichlids      (via sciencedaily.com)     Original source 

Newfound evidence reveals that the upsurge of the exotic Nile perch in Lake Victoria had long-lasting effects on the genetic diversity of various local cichlid species, report scientists. Through large-scale comparative genomic analyses, the researchers found concrete proof in the collective genome of multiple species that this artificially introduced perch decimated many local fish populations, causing a 'bottleneck effect.'

Previously uncharacterized parasite uncovered in fish worldwide      (via sciencedaily.com)     Original source 

Using genome reconstruction, scientists unveiled a once 'invisible' fish parasite present in many marine fish world-wide that belongs to the apicomplexans, one of the most important groups of parasites at a clinical level. However, it had gone unnoticed in previous studies. The parasite is geographically and taxonomically widespread in fish species around the planet, with implications for commercial fishing and oceanic food webs.

Ancient polar sea reptile fossil is oldest ever found in Southern Hemisphere      (via sciencedaily.com)     Original source 

An international team of scientists has identified the oldest fossil of a sea-going reptile from the Southern Hemisphere -- a nothosaur vertebra found on New Zealand's South Island. 246 million years ago, at the beginning of the Age of Dinosaurs, New Zealand was located on the southern polar coast of a vast super-ocean called Panthalassa. 'The nothosaur found in New Zealand is over 40 million years older than the previously oldest known sauropterygian fossils from the Southern Hemisphere.

The genetic 'switches' of bone growth      (via sciencedaily.com)     Original source 

In mammals, only 3% of the genome consists of coding genes which, when transcribed into proteins, ensure the biological functions of the organism and the in-utero development of future individuals. But genes do not function alone. They are controlled by other sequences in the genome, called enhancers, which, like switches, activate or deactivate them as required. A team has now identified and located 2700 enhancers -- among millions of non-coding genetic sequences -- that precisely regulate the genes responsible for bone growth. This discovery sheds light on one of the major factors influencing the size of individuals in adulthood, and explains why their failure could be the cause of certain bone malformations.

Modifying genomes of tardigrades to unravel their secrets      (via sciencedaily.com)     Original source 

Some species of tardigrades are highly and unusually resilient to various extreme conditions fatal to most other forms of life. The genetic basis for these exceptional abilities remains elusive. Researchers have now successfully edited genes using the CRISPR technique in a highly resilient tardigrade species previously impossible to study with genome-editing tools. The successful delivery of CRISPR to an asexual tardigrade species directly produces gene-edited offspring. The design and editing of specific tardigrade genes allow researchers to investigate which are responsible for tardigrade resilience and how such resilience can work.

Ancient Syrian diets resembled the modern 'Mediterranean diet'      (via sciencedaily.com)     Original source 

Thousands of years ago, people in ancient Syria likely ate mostly grains, grapes, olives and a small amount of dairy and meat -- similar to today's 'Mediterranean diet,' according to a new study.

Ritual sacrifice at Chichén Itzá      (via sciencedaily.com)     Original source 

Rising to power in the wake of the Classic Maya collapse, Chichen Itz was among the largest and most influential cities of the ancient Maya, but much about its political connections and ritual life remain poorly understood. Close kin relationships, including two pairs of identical twins, suggests a connection to the Maya origin myths of the Popol Vuh.

Novel Genetic Clock discovers oldest known marine plant      (via sciencedaily.com)     Original source 

An international research team has discovered the oldest known marine plant using a novel genetic clock. This 1400-year-old seagrass clone from the Baltic Sea dates back to the Migration Period. The research project is a significant step towards better understanding and protecting marine ecosystems.

Marsupials key to discovering the origin of heater organs in mammals      (via sciencedaily.com)     Original source 

Around 100 million years ago, a remarkable evolutionary shift allowed placental mammals to diversify and conquer many cold regions of our planet. New research shows that the typical mammalian heater organ, brown fat, evolved exclusively in modern placental mammals. The research team demonstrated that marsupials, our distant relatives, possess a not fully evolved form of brown fat. They discovered that the pivotal heat-producing protein called UCP1 became active after the divergence of placental and marsupial mammals. This finding is crucial for understanding the role of brown fat in mammalian evolution, endothermy, and metabolism.

Early summer fishing can have an evolutionary impact, resulting in smaller salmon      (via sciencedaily.com)     Original source 

A new genetic study found that heavy fishing in the early part of the fishing season may result in younger and smaller Atlantic salmon. This information can help to conserve large fish essential for the diversity and viability of salmon populations.
