Cichlid variation do not primarily originate from random mutations but from engineered systems.
Darwin anticipated “innumerable transitions” in the fossil record, but such a rainbow of transitional forms has never been found.
Transposable elements modify gene regulation in maize to confer drought tolerance, alter flowering time, and enable plants to grow in toxic aluminum soils.
Neurons in a rat’s whiskers “represent multiple stimulus features in a tiled and continuous manner, thus encoding large regions of a complex sensory space.”
A journal article suggests that an impressive instance of unguided evolution has been directly witnessed.
