Final answer:
Intelligent Design Theory is an updated creationist claim against evolution suggesting the work of an intelligent designer; it is not scientifically testable and is not supported by the scientific community, unlike the widely accepted theory of evolution.
Step-by-step explanation:
The term for an updated version of creationism that claims to propose an evidence-based argument to contradict the theory of evolution is Intelligent Design Theory. This theory argues that the complexity within living organisms cannot be fully explained by natural selection and instead suggests the need for an intelligent designer. Despite the claims, it does not qualify as a scientific theory because it cannot be tested or measured and does not give rise to research programs that can further our understanding of the natural world. In contrast, the scientific theory of evolution is widely accepted among scientists, with over 97 percent of scientists agreeing on its validity. It is important to distinguish between the scientific use of the term 'theory' as a well-supported and tested framework, and the common use of the term which refers to a speculation or hypothesis.
