Answer:
Due to early flowering in the mustard plant.
Explanation:
The scientists discovered that the flowering time of the field mustard had changed by observing more mustard plants which produces earlier flowers. The behaviour of the mustard plant change due to the change that occur in the environmental conditions that leads to early flowering in mustard plant. If this early flowering occurs for more generation, then the mustard plant will adopt this type of behaviour in normal environmental conditions that experience by the mustard plant.

this is the reason 
----- now the simplified answer 
the scarlet snake has a very random ( rare ) genetic variation , it mimcs or
 ( behaves a like or looks like  coral snake ) , it turns out that this trait  helps the snake high chance of survival, snake with this kind of trait are often likely to reproduce and pass their traits to their children

Explanation:
Naturalists began to focus on the variability of species; the emergence of paleontology with the concept of extinction further undermined static views of nature. In the early 19th century Jean-Baptiste Lamarck (1744–1829) proposed his theory of the transmutation of species, the first fully formed theory of evolution.
In classical Latin, though, evolution had first denoted the unrolling of a scroll, and by the early 17th century, the English word evolution was often applied to 'the process of unrolling, opening out, or revealing'. It is this aspect of its application which may have been behind Darwin's reluctance to use the term.
