Simply put, descent with modification means that traits are passed down from generation to generation and sometimes undergo changes or modifications over time. These changes may be caused by Natural Selection or even a mutation of DNA. The term became popular when Charles Darwin used it in his book The Descent of Man.

What is an example of descent with modification?
Beetles of a different color Most of the beetles in the population (say 90%) have a gene for green coloration and a few of them (10%) have a gene that makes them brown. Several generations later, things have changed: brown beetles are more common and make up 70% of the population.

Why did Darwin call it descent with modification?
Because characteristics are inherited, these traits will be better represented in the next generation. This will lead to change in populations over generations in a process that Darwin called descent with modification.

What is the difference between evolution and descent with modification?
Evolution is a combination of descent with modification and natural selection. Descent with modification is the evolutionary mechanism that produces change in the genetic code of living organisms.

Who defined evolution as descent with modification?
The first of Darwin’s fundamental insights was the formal description of evolution as we understand it today. He described evolution as descent with modification, postulating the common ancestry of all living things.

Is evolution the same as descent with modification?
Repeated branching events, in which new species split off from a common ancestor, produce a multi-level “tree” that links all living organisms. Darwin referred to this process, in which groups of organisms change in their heritable traits over generations, as “descent with modification.” Today, we call it evolution.

What is the difference between descent with modification and natural selection?
This type of change led to the process of natural selection of a particular type of individuals in the given population. Natural selection is a process. However, descent with modification is the outcome.

What is an example of descent with modification Darwin?
For example, a population of giant tortoises found in the Galapagos Archipelago was observed by Darwin to have longer necks than those that lived on other islands with dry lowlands. These tortoises were “selected” because they could reach more leaves and access more food than those with short necks.

What is descent through modification?
Evolution is descent with modification: that is, the anatomical traits and other features of populations change over time from generation to generation. These modifications occur relatively slowly on average: small incremental changes added up over many generations.

What are examples of common descent?
Ancestral organism shared by two or more descendent lineages — in other words, an ancestor that they have in common. For example, the common ancestors of two biological siblings include their parents and grandparents; the common ancestors of a coyote and a wolf include the first canine and the first mammal.

Which of the following best explains descent with modification?
The correct answer is (B) Natural selection produces individuals most able to survive and reproduce under current local conditions.
