The analogy of a tree for the organization of species, based on phylogeny, illustrates how species evolve and diverge from common ancestors over time. Just as a tree has branches that grow and split, phylogenetic trees depict evolutionary relationships, showing how different species are related through shared ancestry. Each branch point represents a divergence, highlighting the lineage's path and the accumulation of genetic changes. This visual representation helps scientists understand biodiversity and the evolutionary history of life on Earth.
Evolutionary relationships
The evolutionary history of an organism is called its ontogeny. This is a study of biology that focuses on the origin of organisms.
Phylogeny is the study of evolutionary relationships among organisms. It aims to reconstruct the evolutionary history of species using genetic, morphological, and behavioral data. Phylogenetic trees represent these relationships and can provide insights into the patterns and processes of evolution.
Human phylogeny is the study of the evolutionary history and relationships of humans and our ancestors. It encompasses the exploration of genetic, anatomical, and behavioral traits to understand how humans have evolved over time. By examining the divergence and descent of different human species, researchers can reconstruct the evolutionary tree of humans.
The phrase "ontogeny recapitulates phylogeny" suggests that the development of an individual organism (ontogeny) mirrors the evolutionary history of its species (phylogeny). In the context of language origins, this can be simplified to say that the way a child learns language reflects the stages of language development throughout human history. Essentially, individual language acquisition can echo the broader evolution of language itself.

Phylogeny.
Evolutionary relationships among species and higher groups of species.
I think you mean phylogeny. Phylogeny is the evolutionary history of a species or group of related species.
The evolutionary history of a species is often displayed in a phylogenetic tree. This will clearly show the history of the species, which is also known as phylogeny.
Phylogeny
Evolutionary relationships
Phylogeny is the evolutionary history of a species. this establishes relationships between species, i.e., it shows similarities between species. since taxonomy deals with classifications of organisms, phylogeny helps in grouping organisms by presenting the similarities and differences of organisms.
Phylogeny is the study of evolutionary relation among groups of organisms (e.g. species, populations), which is discovered through molecular sequencing data and morphological data matrices.
Species can be classified based on their physical characteristics (morphology), genetic makeup (DNA), and evolutionary relationships (phylogeny).
