Family quarrels in seeds reveal the ways parents and offspring sometimes evolve in conflicting directions
It's spring, finally—and in the tree branches a battle is brewing. A robin returns to her nest with an earthworm. Her nestlings all beg, but only one will get this meal. And while Mom has an interest in making sure that ...

Interplay of pollinators and pests influences plant evolution
Brassica rapa plants pollinated by bumblebees evolve more attractive flowers. But this evolution is compromised if caterpillars attack the plant at the same time. As bees pollinate them less effectively, the plants increasingly ...

Introduced daisy changes its appearance on Australian beaches, defying evolutionary expectations
In less than a century since it was introduced to Australia, the South African beach daisy has drastically changed its appearance – a clear and unusual example of rapid evolution in plants, a new study led by UNSW scientists ...

A small fish provides insight into the genetic basis of evolution
Genetic analysis of sticklebacks shows that isolated populations in similar environments develop in comparable ways. The basis for this is already present in the genome of their genetic ancestors. Evolutionary biologists ...

Heredity matters: Ancestral protease functions as protein import motor in chloroplasts
Over 1 billion years ago, a relationship began between the ancestor of all living plants and a type of bacterium that paved the way for the evolution of life as we know it. The single-celled algal ancestor engulfed, but crucially, ...

Theory suggests root efficiency, independence drove global spread of flora
A new theory of plant evolution suggests that the 400 million-year drive of flora across the globe may not have been propelled by the above-ground traits we can see easily, but by underground adaptations that allowed plants ...

Plants are given a new family tree
A new genealogy of plant evolution, led by researchers at the University of Bristol, shows that the first plants to conquer land were a complex species, challenging long-held assumptions about plant evolution.
