Conserved Quotes
We solved the riddle by finding this really ancient element conserved throughout evolution that acts as a sensing mechanism and tells these fungi when they've changed their environment.

We can't look at just the side-to-side movement... but in terms of the combined side-to-side and forward movement, penguins conserved up to 80 percent of the mechanical energy required for walking. This was quite high, because other measurements for humans and other birds have found that they recovered only up to 70 percent of the mechanical energy.

One argument is that it was conserved to help us lift buses off of pedestrians who just got hit. My belief is that nature conserved the stress mechanism because of its effect on gestation. Natural selection doesn't care about individuals, it just wants poundage and conservation of genes. It found a way to maximize the pounds and the genes.

Knowing the structure of Dicer sets the stage for understanding how Dicer enzymes are involved in other phases of the RNA interference pathway. In human cells, the evidence points to Dicer being part of a larger molecular complex that directs the RNA interference process. The core structure of Dicer has been highly conserved by evolution and could serve as a guide in redesigning the RNA molecules that direct specific gene-silencing pathways.
