Researchers found that flower constancy is an optimal strategy balancing cognitive and travel costs, not just a memory constraint. Bees decrease constancy when flowers have similar colors or are clustered, but maintain high constancy in mixed environments.
Researchers mapped yerba mate's genome, discovering an ancestor that duplicated its genome 50 million years ago. This event led to the evolution of caffeine biosynthesis in yerba mate and coffee through convergent pathways. The study provides opportunities for creating plant varieties with new characteristics.
The Virginia Tech analysis extends the chart of life by nearly 1.5 billion years, mapping the rise and fall of ancient life from the Proterozoic Eon. The study reveals that global ice ages accelerated the pace of evolution in species counts.
A new robust classification system for termites has been developed through expert consensus and extensive data analyses. The updated 'dictionary' of termites resolves ambiguity in the previous system, providing a solid platform for studying termite diversification and ecosystem roles.
Two groups of leaf-nosed bats, one small and one large, are an example of parallel evolution where they evolved similar features independently despite living on the same islands. The larger bats have adapted to eat bigger prey, using lower sonar frequencies, while the smaller bats use higher frequencies.
A study found that weedy rice's promiscuity allows it to crossbreed with wild rice, enabling it to adapt and outcompete cultivated rice. This process, called adaptive introgression, has contributed to the evolution of Southeast Asian weedy rice.
A team of scientists and philosophers identifies a new law of nature that governs the evolution of complex systems, including plants, animals, stars, and minerals. The law states that complex systems evolve to states of greater patterning, diversity, and complexity, regardless of whether they are living or nonliving.
A MedUni Vienna study examining the connection between brain structure and function found that brain shape evolved parallel to its capabilities. The research analyzed 90 species of Euarchontoglires, revealing clusters of growth patterns linked to cognitive abilities.
A new genus of scorpionflies has been discovered in Nepal, characterized by a spindly and extremely elongated abdomen. The males have long grasping pincers for mating, while the females lack these distinctive features, making classification more challenging.
Researchers found that eyespots on animals' bodies make them more cautious when approached from the side, but not from directly behind or in front. This discovery sheds light on why eyespots have evolved to be symmetrical and effective predators.
A recent study published in Science found that urbanization drives the evolution of white clover in cities worldwide. The researchers collected over 100,000 plants from 160 cities and discovered that plants producing less cyanate were more common in urban areas compared to non-urban areas.
A team of Skoltech and IITP RAS researchers discovered adaptive parallel mutations in protein-coding sequences of 46 amphipod species from Lake Baikal, affecting several thousand genes. The findings suggest that these mutations are driven by the species' need to adapt to their environment.
Researchers from the University of Helsinki found that genetic parallelism, a phenomenon where similar changes occur in different populations, is approximately 10-fold higher in the Eastern Pacific compared to the rest of the world. This suggests that the conditions for parallel evolution may be exceptional rather than common.
The study found that the giant saguaro, organ pipe, senita, and cardón have scrambled family relationships due to long generation times. However, some similarities like succulent flesh were retained by some cacti through ancient genes.
Fossils of an extinct 'storyteller' crocodylian from Peru show evidence of parallel evolution of river-dwelling lifestyle and protruding, telescoped eyes in South American and Indian species. The study suggests that these features evolved separately to help catch fish in habitats.
Scientists studied evolutionary rates of nearly 20,000 human genes and found that genes involved in the same biological pathways change their rate of evolution in parallel. This signature can help identify partner genes that may work together in biochemical pathways, providing clues to their function.
A new model of sound change shows that evolutionary principles can account for striking phonetic similarities across unrelated languages, as well as the rarity of certain sounds. Human perception and articulation make certain kinds of sound change more frequent than others, resulting in emergent properties of language.
A new species of spinosaurid dinosaur, Suchomimus tenerensis, is discovered in the Ténéré Desert with a long, narrow, crocodile-like skull. The fossil remains suggest that this predator had curved claws like giant meathooks and was about 11 meters long.
