A dog learns to sit on command, a person hears and eventually tunes out the hum of a washing machine while reading … The capacity to learn and adapt is central to evolution and, indeed, survival.

Life’s leap from single-celled to multicellular organisms marks a pivotal moment in evolutionary history. This transformation laid the foundation for the complex life forms we see today. By studying ...

A growing body of peer-reviewed research is building the case that single-celled organisms, creatures with no brain, no neurons, and no nervous system at all, can exhibit habituation, one of the ...

Stentor is a trumpet-shaped, single-celled organism that can grow up to 2 mm long. In its native habitat of ponds or lakes, Stento r attaches its slender end (called the holdfast) to leaves or twigs ...

Up until recently, habituation -- a simple form of learning -- was deemed the exclusive domain of complex organisms with brains and nervous systems, such as worms, insects, birds, and mammals. But a ...

Scientists have known for more than a century that a single-celled organism with no nerve cells — much less a brain — can behave in ways that resemble learning. But those observations only went so far ...

Scientists at Queen Mary University of London and the University of Hong Kong have created a mouse with substituted genes from a single-celled organism known as a choanoflagellate. Scientists replaced ...

Humans like to think that being multicellular (and bigger) is a definite advantage, even though 80% of life on Earth consists of single-celled organisms—some thriving in conditions lethal to any beast ...
