Partly yes. When organisms procreate there are always mutations, (mistakes), in the copying of the DNA. When a mutation or series of mutations helps a species to live through changes in environment it would be considered more successful and would be more likely to have offspring to pass on those mutations to the next generation.

What is common descent with modification?
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.
Generally evolution by natural selection occurs quite slowly over?
Evolution through natural selection occurs slowly over millions of years. It has been hypothesized that evolution is the result of positive mutations that occur in a community of organisms that help them survive better. Evolution is essentially descent with modification.
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.
Involves descent with modification?
evolution
Is this statement true or false evolution involves descent with modification?
True.
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."
When micro-evolution occurs over many generations as inherited characteristics leads to changes in populations what has occurred?
Macro-evolution. Or, more accurately, speciation.
Descent with modification or change over time is?
evolution
What word do biologists use when they mean descent with modification?
Evolution?
Charles Darwin's idea of how species change over time is called what?
Descent with modification. This is what Darwin called evolution.
What three word phrase summarizes Darwin's mechanism of evolution?
Darwin used the phrase "descent with modification" (he didn't use the term "evolution")
What phrase did Darwin use instead of evolution?
Descent with modification. Or. Transubstantiation.
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).
Can there be evolution without reproduction?
No. Evolution is defined, in its simplest form, as descent with modification. So reproduction is an essential part of the definition of evolution.
New generations are better suited to the environment than the first generation what is this called?
Descent with modification (Apex)
