Instead of using a family tree, scientists use a(n) _____ tree to track the evolutionary history of a species.

To find information on why the six kingdoms classification changed to five, you can follow these steps:

1. Start by conducting a search on a reliable search engine like Google or Bing. Type in relevant keywords such as "why did the six kingdoms become five" or "reasons for changing six kingdoms classification to five."

2. Look for credible sources such as scientific articles, educational websites, or reputable online encyclopedias. Websites with domain extensions like .edu (educational institutions), .gov (government agencies), or .org (non-profit organizations) are often reliable sources.

3. Read the information provided in various sources to gather different perspectives on the subject. Pay attention to scientific consensus and avoid websites that promote pseudoscience or have biased opinions.

4. One of the major reasons for the change from a six-kingdom to a five-kingdom classification system is the advancement in genetic studies and the discovery of new scientific knowledge. The outdated six-kingdom system, initially proposed by Carl Woese, grouped all prokaryotic organisms into a single kingdom called Monera. However, with the advancement of DNA sequencing techniques, it became clear that there were significant genetic and evolutionary differences between different groups of bacteria, archea, and eukaryotes.

5. As a result, the scientific community adopted a newer classification system called the three-domain system, proposed by Carl Woese and George Fox in the 1990s. This system divides all life forms into three domains: Bacteria, Archaea, and Eukarya. The eukaryotic organisms, previously grouped under a single kingdom called Protista in the six-kingdom system, were further divided into four separate kingdoms: Protista, Fungi, Plantae, and Animalia.

Remember, it is essential to verify the information you find by comparing multiple sources and cross-referencing the information to ensure accuracy and reliability.
