A scientific theory


A scientific theory is accepted as a scientific truth, supported by evidence collected by many scientists. The theory of evolution by natural selection is a classic scientific theory.


A scientific theory is a broad explanation for events that is widely accepted as true. To become a theory, a hypothesis must be tested over and over again, and it must be supported by a great deal of evidence. People commonly use the word theory to describe a guess about how or why something happens.


As you view Know the Difference (Between Hypothesis and Theory), focus on these concepts:


1.the controversy surrounding the words ‘‘hypothesis’’ and ‘‘theory’’,

2.the scientific use of the words ‘‘hypothesis’’ and ‘‘theory’’,

3.the criteria for a ‘‘hypothesis,’’

4.the National Academy of Sciences definition of ‘‘theory’’, and

5.the meaning of the statement, ‘‘theories are the bedrock of our understanding of nature’’.


Advancement is an adjustment in the qualities of living things after some time. Development happens by a procedure called characteristic choice. In natural selection, some living things produce more offspring than others, so they pass more genes to the next generation than others do.


The Cell Theory

The cell hypothesis is another imperative logical hypothesis of science. According to the cell theory, the cell is the smallest unit of structure and function of all living organisms, all living organisms are made up of at least one cell, and living cells always come from other living cells.


The Germ Theory

The germ theory of disease, also called the pathogenic theory of medicine, is a scientific theory that proposes that microorganisms are the cause of many diseases.



With rehashed testing, a few speculations may in the long run end up noticeably logical hypotheses. A logical hypothesis is a wide clarification for occasions that is broadly acknowledged as evident.

Evolution is a change species over time. Evolution occurs by natural selection.

The cell theory states that all living things are made up of cells, and living cells always come from other living cells.

The germ theory proposes that microorganisms are the cause of many diseases.
