a mechanism for evolution; all organisms are related through descent from an ancestor; descendants accumulated adaptations; descent of all organisms from an ancestor that lived in the past; descendants accumulated diverse modifications (adaptations)

if the first one doesnt work try the second

An example of descent with modification is a bacterium that inherits a gene for antibiotic resistance, has a more significant possibility of survival. Natural selection then applies that resistance through the population, forcing scientists to come up with a new antibiotic.

What is darwin's theory of descent with modification?

Darwin described evolution as "descent with modification," the theory that species evolve over time, give rise to new species and transmit a common progenitor.

The means that Darwin proposed for evolution is natural selection.

Thus, a bacterium that inherits a gene for antibiotic resistance,  is an example of descent with modification.
