New study traces how Earth’s alpine plant diversity evolved
Overview: Unraveling the origins of alpine plant diversity A newly published study in Science Advances provides a comprehensive look at the deep-time processes that have shaped the remarkable plant diversity found in Earth’s alpine regions. While the richness of alpine flora has long been documented by ecologists and biogeographers, this research delves into the historical…

Ancient Bee Nests in Fossils Reveal Surprising Behavioral Shifts
New fossil evidence uncovers unusual bee nest behavior In a breakthrough for entomology and paleontology, researchers have identified bee nests preserved in fossils that suggest behaviors never before observed in the fossil record. This discovery challenges long-held views about how ancient bees lived, especially regarding nesting choices and social structure. Traditionally, scientists imagined bee nests…

Ancient bee nests reveal unprecedented early-bee behavior
Groundbreaking fossil finds illuminate a surprising aspect of early bees For decades, scientists have imagined the early bees as small, simple creatures that resembled solitary relatives of today’s honeybees and carpenter bees. A striking new set of fossil discoveries challenges that view, presenting evidence of ancient bee nests built in ways that researchers had not…

A Scientific Sandbox Reveals How Vision Systems Evolved
A Scientific Sandbox for Vision Evolution Researchers at MIT have introduced a computational framework described as a “scientific sandbox”—a flexible environment that lets scientists simulate and study the environmental pressures that shape the evolution of vision. By creating virtual worlds with controllable lighting, textures, motion patterns, and ecological demands, the framework enables the systematic exploration…

Why Eyes Evolved: MIT’s Sandbox for Vision Evolution
Introduction: A New Way to Study Eye Evolution Humans owe much of their perception to a long, winding history of optical innovation. From simple light-sensitive cells to complex retinas, eye design has been shaped by environmental pressures, ecological roles, and energetic costs. Yet we can’t travel back in time to observe these forces directly. Researchers…

Vampire Squid Genome Reveals Secrets of a Living Fossil
Introduction: A Deep-Sea Giant Unveiled The vampire squid (Vampyroteuthis infernalis) has long fascinated scientists and divers alike with its eerie glow, pale body, and shrouded evolutionary history. Now, a landmark study has sequenced its exceptionally large genome, offering a window into the deep-sea past and the broader story of cephalopod evolution. By mapping the vampire…

Chimps That Kill for Territory Gain Reproductive Advantages
Territorial aggression and reproductive payoff Chimpanzees are renowned for their complex social strategies, but a growing body of research suggests that lethal intergroup aggression—killing neighboring groups to claim more territory—may also confer a reproductive edge. A long-running field project led by primatologist John Mitani at the University of Michigan has tracked the Ngogo chimpanzees in…

Sponge vs Comb Jelly: First Animal Debate Ongoing
Introduction: A Heated Question at the Origin of Animals The long-running question of which organisms form the root of the animal tree of life has a new twist. In recent weeks, biologists have revisited the debate between sponges and comb jellies as potential early lineages that shape how we understand animal evolution. While two years…

Sponge vs. Comb Jelly: First Animal Debate Ongoing
Background: Who Is At the Root of the Animal Tree? The question of which lineage marks the origin of animals has long tugged at evolutionary biology. Two candidates dominate the discussion: Porifera (sponges) and Ctenophora (comb jellies). A recent study from UC, mirroring a shift in how scientists interpret ancient genetic data, reaches a different…
