Protists are a group of organisms that are characterized as eukaryotes (they have cells with nuclei) that are neither plants nor animals nor fungi. they are very diverse, and there are many hypotheses about their classification. the cladogram for protists is constantly changing and, sometimes, there are opposite hypotheses that both have data to support them. what is implied by a changing hypothesis?

It is acceptable because data are still being collected.

Explanation:

Protists are very complex organisms, and this kingdom is made up of a great diversity of animals and many of them do not have the same characteristics, making it even more difficult for scientists to make a concrete conclusion about this kingdom. At all times more and more hypotheses about the protists are formulated and tested, this change of hypotheses is always acceptable because the data about the protists is still being collected.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
