Some populations undergo unpredictable and dramatic increases in numbers, sometimes temporarily increasing by 10 or 100 times over a few years, only to follow with a similarly rapid crash.
All populations undergo clonal expansions driven by de novo mutations but remain genetically and phenotypically diverse.
However, if individuals travel to Galápagos to learn about evolution itself for example, how evolution involves many mechanisms, one of which is natural selection, and how populations undergo adaptive radiation then they may be disappointed or misinformed.
We demonstrate that randomly-seeded mixed cell populations undergo rapid condensation and self-organization into discrete epithelial and endothelial structures that are mechanically robust and stable during long term culture.
These platforms can be loaded with large amounts of biological cargo, administered systemically and act at a distance, target specific cell populations, undergo intracellular internalization via endogenous uptake mechanisms, and act as contrast agents or release cargo for therapeutic purposes.
Each year, U.S. ocean fish populations undergo a checkup by the National Oceanic and Atmospheric Administration (NOAA) in a report to Congress, the Status of U.S. Fisheries.
