In descent with modification, new species descend from ancestral species by the accumulation of modifications as populations adapt to new environments.
A lineage is a descent group that can demonstrate their common descent from a known apical ancestor. Decent with modification was an early theory (of evolution) that was set out before people had any idea about genetics and how traits were transferred.

Charles darwin proposed the theory of universal. Genes are the blueprints for making an organism, and, as such, hold information about its every conceivable aspect. However, genetic data suggest that all three kinds of organisms diverged from a common ancestor at about the same time. Descent from a common ancestor, 2.
