What are some possible explanations for rapid evolutionary changes?
Adaptive radiation is one good explanation for rapid evolutionary change. When a dominant taxa goes extinct, such as the dinosaurs, the surviving species/taxa, such as the mammals have many niches that they can now fill, so any variation in individuals against immediate environments can lead to survival and reproductive advantages that translate into rapid allelic changes in populations; rapid evolutionary change.
What is the connection between slow cycling and rapid cycling?
In bipolar disorder, slow cycling refers to experiencing less than four mood episodes in a year, while rapid cycling refers to having four or more mood episodes in a year.

Under what circumstances might rapid evolution occur?
Rapid environmental change results in rapid evolutionary change (as long as it doesn't occur too fast, in which case the organsisms will simply die out). Also the disappearance of the dominant organisms (eg dinosaurs) leaves an empty space in the ecosystem and the remaining organisms will evolve quickly to fill it. Finally, the release of an animal into a new environment or a domesticated animal into a natural environment results in rapid evolution. Two examples are cane toads in Northern Australia which have evolved longer legs so they can travel further and feral cats in Australia reverting back to their natural state (insanely big and evil-looking) in just 4 generations.
Jaundice is caused by the rapid breakdown of?
Jaundice is caused by the rapid breakdown of red blood cells which leads to increased levels of bilirubin.
How can you tell if bilirubin has affected my child?
Bilirubin is the pigment that makes feces brown."Failure of the liver cells to excrete bile, or obstruction of the bile ducts, can cause an increased amount of bilirubin in the body fluids and thus lead to obstructive or regurgitation jaundice.Another type of jaundice results from excessive destruction of erythrocytes (hemolytic or retention jaundice). The more rapid the destruction of red blood cells and the degradation of hemoglobin, the greater the amount of bilirubin in the body fluids.Most bilirubin is excreted in the feces. A small amount is excreted in the urine as urobilinogen."answers.com

How did the Chicago fire stand out in history?

What is severe hemolysis?
Severe hemolysis is a condition characterized by the rapid destruction of red blood cells, leading to a release of hemoglobin into the bloodstream. This can result in symptoms such as anemia, jaundice, and organ damage due to the buildup of waste products from the breakdown of hemoglobin. Severe hemolysis may be caused by various factors, including infections, autoimmune disorders, and certain medications.
