Monophyletism is a term used in evolutionary biology to describe a single ancestral group of organisms. The spelling of this word is "mɒnəʊfaɪlɪtɪzəm" in IPA phonetic transcription. The first syllable "mon" is pronounced as "mɒn," while the second syllable "o" is pronounced as "əʊ." The third syllable "phyle" is pronounced as "faɪl," and the fourth syllable "tism" is pronounced as "tɪzəm." The stress in this word is on the second syllable. Overall, Monophyletism is a complex word with a long and diverse pronunciation.
Monophyletism refers to a concept in evolutionary biology and taxonomy, where a group of organisms is classified based on a single common ancestor. It is a term used to describe a taxonomic group that includes all the descendants of a particular common ancestor, while excluding any other lineages that may have evolved separately from a different ancestor. The term is derived from the Greek words "mono," meaning "single," and "phylon," meaning "tribe" or "race."
In the context of evolutionary theory, monophyletism represents a genealogical relationship among organisms, suggesting that they all share a common evolutionary history. This means that the group originates from a single ancestral species and has evolved into various subgroups or species over time. The classification system based on monophyletism is often referred to as cladistics or phylogenetics.
The principle of monophyletism is important in understanding the relationships and evolutionary history of organisms. By identifying monophyletic groups, scientists can determine the evolutionary relatedness between different species or populations. This classification system based on monophyletic groups helps in understanding the evolutionary transitions, patterns of diversification, and shared characteristics among organisms.
In summary, monophyletism is an essential concept in evolutionary biology and taxonomy, representing a taxonomic group that includes all the descendants of a common ancestor. It provides a framework for understanding the evolutionary relationships and shared ancestry among organisms.
In hematology, the doctrine that all the blood-cells are derived from one common ancestor, probably the myeloblast.

The word "monophyletism" is derived from the combination of two Greek roots: "mono" meaning "single" or "one", and "phyletism" which comes from "phylon" meaning "tribe" or "clan".
In the context of biology and evolutionary theory, "monophyletism" refers to a concept that suggests a single ancestral group gave rise to all the species in a particular taxonomic group. It is used to describe a pattern of evolution where all the organisms in a given category share a common ancestor, forming a monophyletic group.
