Descent with modification is a principal that is closely linked to natural selection. It means that the descendants of a parent species will have been slightly modified, and their descendants will be slightly modified, and so on. Natural selection is the engine that drives this modification- and ensures that this change is in a direction that better suits the species to its environment. In this way, species are constantly changing, though extremely slowly.
The geological record can show how a certain species has slowly changed over time. As we follow a species through hundreds of thousands of years, parts of its organization become modified as the species becomes better suited to its environment, or to other environments that allow it to extend its range. These changes in physical aspects can be seen in fossils and show, for example, how a fin for swimming evolved into a leg for walking.
What else can I help you with?
Fossils show evidence of descent with modification?
yes they do

How can fossils help show that continental drift happened?
It can help show that continental drift happened, if you find the same fossils on different continents. This would mean that the continents had to be close together if the fossils are found on land.
How do fossils show changes in related species?
Fossils are used to show changes because they are permanent. These fossils are also old and show evolutionary changes in species alive today.
How are fossils used to show changes in Antarctica?
plant fossils (glossopteris) were found there.
How do fossils help scientist?
Fossils help scientists by leaving a record for scientists to use. Fossils can help show a scientist which type of animal was living in an area during a certain time. This gives scientists a better idea of what that area was like hundreds of millions of years ago all the way through today.
Fossils show that there have been many?
Fossils show that there have been many different species of organisms that have lived on Earth throughout its history. These fossils provide important clues about the evolution and biodiversity of life on our planet.
How do fossils help geologists?
Geologists use fossils to interpret past environments, age rock layers, and understand the history of life on Earth. Fossils can provide information about the evolution of species, past climate conditions, and even the movement of continents over time. By studying fossils, geologists can reconstruct the Earth's history and better understand geological processes.
Do fossils show a complete history?
No. Because there are not enough fossils to do any more than to guess.
Why are fossils important scientists?
In simplest terms, fossils show what living things were like long ago.
What information can artifact and fossils provide?
Fossils can show the kind of environment animals lived in millions of years ago. They can also show how certain animals have evolved. Artifacts can show the kind of society humans lived in at a certain time.
What are forming fossils?
Fossils are formed in sedimentary rocks, which has multiple layers to show the level of soil back then.
