A new megastigmane glycoside, grasshopper ketone 3-O-primveroside (1), was isolated from the methanolic extract of the whole herbs of Sinocrassula indica (Crassulaceae). Its structure was elucidated on the basis of spectral and chemical evidence.
What is Evolution? QUESTION: What is evolution? ANSWER: Evolution is technically defined as: a gradual process in which something changes into a different and usually more complex or better form. As it is most famously used, evolution is the process by which an organism becomes more sophisticated over time and in response to its environment. The Theory of Evolution is currently the most popular concept of how life reached its current state. Evolution as a biological mechanism is driven by natural selection.
The basic mechanisms of evolution include natural selection, genetic drift and mutation. Natural selection is a process in which the population of organisms that have adapted to their environment increases more than the population of less well-adapted forms. This concept was first explained in Charles Darwin's theory of evolution.
