Biology lineage
An evolutionary lineage is a temporal series of populations, organisms, cells, or genes connected by a continuous line of descent from ancestor to descendant. Lineages are subsets of the evolutionary tree of life. Lineages are often determined by the techniques of molecular systematics. See more Lineages are typically visualized as subsets of a phylogenetic tree. A lineage is a single line of descent or linear chain within the tree, while a clade is a (usually branched) monophyletic group, containing a single ancestor … See more • Clade • Linnaean taxonomy See more WebBiological lineage is the process involving a series of organisms, populations, and cells. It involves the study of the ascent of organisms from parent to progeny, further based on the evolutionary tree of life, keeping a track of the order of the developmental stages come across so far. The evolutionary lineage is known as a clade, referring ...
