Cichlid and stickleback fish are two of the most iconic examples of adaption that biologists present as evidence for the plausibility of evolutionary processes.
Cichlid variation do not primarily originate from random mutations but from engineered systems.
The “long-winged” phenotype is generated if the environmental conditions deteriorate due to reduced food supply or overpopulation.
Transposable elements modify gene regulation in maize to confer drought tolerance, alter flowering time, and enable plants to grow in toxic aluminum soils.
Cells are equipped with sensors that recognize touch and respond accordingly. They can even reach out to other cells with nanoscopic tunnels and share parts.
