A testable hypothesis is valuable, even if evidence shows that it is false

Explanation:

A hypothesis sets a base on which the experiment is conducted by determining the design and protocol for which the scientists will take in the experiment. A hypothesis, therefore, should be developed based on good research prior to beginning to conduct the experiment. Usually a good hypothesis is one of no change called a 'null hypothesis'. Based on an analysis of data from the experiment, a hypothesis could either be rejected or accepted. If the null hypothesis is rejected then the alternative - which is usually the flip side of the null hypothesis- is  adopted as true.

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
