The Kingdom Protista has been abandoned by scientists for a long time.
Questions to ask:
It’s only recently that they have started to take an interest in the kingdom again. This is because of new research and the discovery of previously unknown organisms, such as Euglena gracilis and Trichophrya erythraea. The question that we need to ask ourselves now is why did it take so long? Why were these organisms ignored for so many years?
The answer to this question is not simple. It has been a long time since the kingdom was abandoned, and there are many reasons why it may have happened. Some of these potential causes include: people abandoning protista because they didn’t understand them; changes in scientific interests; insufficient research funding for the Kingdom Protista; or neglecting to keep up with recent developments that could be applicable to studying organisms from the Kingdom Protista. We need more research on this topic before we can be sure about any of these possibilities though!
Is “mystery bacteria” an unknown organism?
If so, should I add it as another example? Does anyone know how I might find out if my hypothesis about scientists neglecting their duties when dismissing other
Here are the reasons for this:
The kingdom protista is a large, diverse group. It includes over 20 phyla of single celled organisms and one or two multicellular eukaryotes in colonies (e.g., Volvox).
Phylogenetic studies
Phylogenetic studies suggest that there were several independent origins of animals from different groups within the Kingdom Protista. This complicates any study on animal evolution because it makes it difficult to discern what traits evolved first, second, etcetera before they were passed onto other kingdoms like chordates – which would be an important question in understanding how our own lineage developed hearts which pump blood through veins with valves; lungs used for respiration; central nervous system providing feedback to limbs; or eyes for vision.
It has been hypothesized that the colonial organisms in Kingdom Protista may have led to animals with a certain combination of traits, though more evidence is needed to back up this theory. More recently protists were thought to be an excellent model organism because they are simple enough to study and their genomes can provide information on life processes which we do not understand well yet such as how our cells use DNA sequence variations and proteins encoded by genes in order communicate with other cells (in multicellular eukaryotes) or between different parts of one cell (in single cellular ones).
