modificatoin
It means that new species descended from preexisting species, and species must be able to change over time.
Common descent
descended from a common ancestor
The rise of two species from one species in a continuing process that resembles the branching of a tree or bush. This is called phylogenetic evolution and is the main driver of species arising over time.
Darwin used the idea of a "tree of life" with each species being a leaf. So a major group - such as insects - would be a branch, but the tree illustrated the idea that everything is related leading back to the common trunk.

The principle that all species were derived from common ancestors is known as Common descent.
It means that new species descended from preexisting species, and species must be able to change over time.
Natural selection
Yes, but it needs some additions like Mendelian Genetics that Darwin did not have. These additions have already been made.
