Scientists discover single cell creatures can learn new behaviours despite having no nervous system. ... “These creatures are so different from animals with brains.

The research team began by analyzing gene expression — which bits of DNA are converted into RNA used to make cell proteins — in more than 65,000 individual cells across four placozoan species.

Sponges are more closely related to us than some animals with a nervous system. John Timmer – May 17, 2023 2:38 pm | 34 These complex creatures seem to be the earliest branch of the animal tree.

Shimmering, gelatinous comb jellies wouldn’t appear to have much to hide. But their mostly see-through bodies cloak a nervous system unlike that of any other known animal, researchers report in ...

He argues that these jellies evolved their nervous system independently, and that other understudied animals may have done the same. Unraveling this diversity could lead to a deeper understanding ...

An international team of scientists has uncovered a fascinating piece of the evolutionary puzzle: how the ventral nerve cord, a key component of the central nervous system, evolved in ecdysozoan ...

Almost all eukaryotic organisms, from plants and animals to fungi, can’t survive without mitochondria – the “powerhouses of the cell,” which generate chemical energy using oxygen.
