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.
Best Answer: 1. Evolution is defined as the change in the allele frequency in a population. Or in simpler terms, the change in the heritable traits in a population (such as a species) over time. Or in even simpler terms ...*evolution is change* (but change in a *species* over time, not an individual. However, there is also something called the theory of evolution (or TOE).irst evolution itself is not a theory, the theory of evolution for the development of species is a theory. Second, a theory means that it is an explanation. It has nothing to do with whether is has been proven. Nothing can be proven in science by definition.
