Asexual reproduction usually leads to a lack of genetic diversity. Not for these ants

Genetic diversity is essential to the survival of a species. It's easy enough to maintain if a species reproduces sexually; an egg and a sperm combine genetic material from two creatures into one, forming a genomically robust ...

Zooplankton study challenges traditional views of evolution

In new research, Arizona State University scientists and their colleagues investigated genetic changes occurring in a naturally isolated population of the water flea, Daphnia pulex. This tiny crustacean, barely visible to ...

3D genome extracted from 'freeze-dried' woolly mammoth

About 52,000 years ago, the skinned hide of a Siberian woolly mammoth was exposed to conditions so frigid that it spontaneously freeze-dried, locking its DNA fragments into place.

Evolutionary biologists investigate how plant cold specialists can adapt to the environment

Plant cold specialists like the spoonworts have adapted well to the cold climates of the Ice Ages. As cold and warm periods alternated, they developed a number of species that also resulted in a proliferation of the genome.

First ever 3D reconstruction of 52,000-year-old woolly mammoth chromosomes thanks to serendipitously freeze-dried skin

An international research team has assembled the genome and 3D chromosomal structures of a 52,000-year-old woolly mammoth—the first time such a feat has been achieved for any ancient DNA sample.

Genomic insights into adaptation to bipedal saltation and desert-like habitats of jerboas

Jerboas are a lineage of small rodents displaying atypical mouse-like morphology with elongated strong hindlimbs and short forelimbs. A research team has recently sequenced and reported the chromosome-scale genome of the ...

Why do dogs have different coats? Experts explain—and give grooming tips for different types

Dog hair comes in many varieties, from shaggy to short, curly to straight. If you live with a dog, you live with their hair—on your couch, in your clothes, it's everywhere!

How the genome diversity of major crops tells the story of their evolution

On March 27, 2024, a study published in the journal Nature announced that the sugarcane genome had at last been cracked. This was a remarkable achievement because of the complexity of the sugarcane's genome. That of rice, ...

Identification of a von Willebrand factor type A protein affecting both grain and flag leaf morphologies in wheat

Wheat production is essential for global food security, and continual improvement to grain yield is necessary to meet the nutritional demands of the expanding human population. Grain size is positively correlated with grain ...
