Rapaza viridis, a single-celled predator, performs #photosynthesis by stealing and temporarily retaining chloroplasts from its algal prey, a process known as kleptoplasty. It actively maintains these stolen organelles by transporting its own host-encoded proteins into them.

Female mosquitofish (Gambusia hubbsi) adapted to specific environmental pressures exhibit severe aggression toward males from different habitats, creating a behavioral reproductive barrier that can drive the evolution of entirely new species.

Aggressive female fish put stop to mating - may lead to new species

The research complements “female choice” in the evolutionary process and instead highlights “female resistance”

"Starships" are massive mobile genetic elements that actively transport transposable elements (TEs) across different fungal species, driving rapid genetic restructuring and accelerating genome evolution.

Fungi used in pest control: Traveling across fungal genomes in “spaceships”

Massive exchange of mobile genetic elements between fungi can impair their effectiveness against insects and ticks.

The diversity of forms across #marine species is fundamentally driven by the physical properties of tissues, such as their capacity to contract, stretch, and resist deformation, which act in tandem with genetic factors to dictate an organism's final morphology.

Mechanical forces drive the diversity of life

Why do animals display such a wide range of shapes, even within the same group?

Fossil From 310 Million Years Ago Rewrites the Story of Fish Evolution

A University of Michigan researcher has discovered an early innovation in the way fish eat. A scientist from the University of Michigan has helped uncover the earliest evidence of a tongue-like biting structure in an ancient fish. This adaptation, first appearing around 310 million years ago, marked the moment when fish began using their gill [...]
