evolution
descent with modification
Darwin used the phrase "descent with modification" (he didn't use the term "evolution")
Darwin used the phrase "descent with modification" in his book "On the Origin of Species" instead of the word "evolution." He used this phrase to describe the process by which species change over time through natural selection.

Charles Darwin's idea of how species change over time is called natural selection. This process involves the survival and reproduction of organisms that are best adapted to their environment, leading to gradual changes in the characteristics of a population.
Descent with modification
Descent with modification
The theory of evolution by natural selection.
Depends if the population increase is related to a selected pressure, you could then argue that the population change is an extended phenotype.Typically population fluctuations are NOT considered decent with modification and are seen as random drifts with out any selective pressures working on them.Good question,
Darwin's theory of descent with modification, also known as evolution by natural selection, proposes that species evolve over time through the process of variation and differential survival and reproduction. This means that species descend from common ancestors and accumulate changes or modifications that help them adapt to their environment.
DNA contains the genetic information that determines an organism's traits. Through mutations and genetic variations, DNA can change over time, leading to differences in traits among individuals within a population. This supports Darwin's theory of descent with modification, as it provides a mechanism for how species can evolve and adapt to their environment over generations.
Common descent with modification is the concept that all organisms on Earth are descended from a common ancestor, and that over time, through the process of natural selection, genetic changes accumulate in populations leading to the diversity of life we see today. This idea was proposed by Charles Darwin in his theory of evolution.
