In short: Evolution. It means that a common ancestor is shared, but through small modifications over long periods of time, there is a large diversity.

Concept that each living species has descended with changes from other species over time?
Descent with modification
What does descent modification imply about the relationships among the different species on earth today?
That the offspring of one species may adapt to it's surroundings and live longer then though without the modification.
How does Darwin's principle of descent with modification explain the characteritics of todays species?
Yes, but it needs some additions like Mendelian Genetics that Darwin did not have. These additions have already been made.
What should each species on Earth today have according to the theory of Common Descent?
The theory of Common Descentbelievesthat all species on earth have a common ancestor.
What explains the distribution of finch species on the Galapagos Islands?
They had descended with modification from a common mainland ancestor.
New generations are better suited to the environment than the first generation what is this called?
Descent with modification (Apex)
What is it called when newer generations are better suited to an environment than the first generation is?
descent with modification
How did Darwin explain the patterns of distribution of plants and animals?
He explained them in terms of descent with modification, common descent and natural selection.
Involves descent with modification?
evolution
Is descent with modification caused by natural selection?
No, it's the other way around: descent with modification is what you need for natural selection to happen.
What is the evolutuionary theory?
The theory of descent with modification.
When micro-evolution occurs over many generations as inherited characteristics leads to changes in populations what has occurred?
Macro-evolution. Or, more accurately, speciation.
What is the Descent of modification is also known as?
Evolution. Darwin used the term "descent with modification"-- not "evolution"-- however, later people began to use the term "evolution."
Descent with modification or change over time is?
evolution
Fossils show evidence of descent with modification?
yes they do
What is descent with modification?
Descent with modification encapsulates the two key ideas central to the theory of evolution. These are that modifications (mutations) occur, and that these mutations are inheritable (passed on to descendants or offspring).
What is descent modification?
IT is when gravity collides with snakes so the organisms
