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 and all its descendants. Phylogenetic trees are typically created from DNA, RNA or protein sequence data. Apart from this, morphological differences and similarities have been, and still are used to create phylogenetic trees. Sequences from different individuals … WebOn a grand scale, the process of speciation leads to an evolutionary pattern that is something like a forking road. A lineage may persist for many generations and then split, with each resulting lineage taking its own path. Some paths end up leading to dead-ends (i.e., extinction); others diverge many more times, leading to new lineages. The result of … pride health and social care ltd

WebIn biological phylogenetics, a clade (from Ancient Greek κλάδος (kládos) 'branch'), also known as a monophyletic group or natural group, [1] is a grouping of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree.
