scientists discovered a shorter theory to replace it
The answer is scientists found new evidence to prove it invalid
Steady State Theory of origin of the universe has been rejected due to new findings about how the universe was formed through carefully observing it which faulted past theories. This validates the option which states that scientists found new evidence to prove it invalid.
Online water monitoring
New York City was the first major city in the world to offer online water tracking, as part of the city’s shift to the equivalent of a smart grid for water.

The study of artificial selection by Darwin helped him to establish his theory of evolution via natural selection. One of the animals Darwin examined in detail was the domestic rock pigeon. In the 1850s breeding of pigeons was an ancient past time, thus, Darwin decided to keep and breed the pigeons by himself.
While studying pigeons, Darwin established scrupulous determinations of their skeletons and wondered at the breeds' distinct colors, behaviors, and proportions. He also observed the patterns of inheritance of various features, and he demonstrated that birds of very distinct breeds can, however, generate fertile offspring. Thus, supporting the theory that they all originated from a single species.
