Macro-evolution. Or, more accurately, speciation.
What word do biologists use when they mean descent with modification?
Evolution?

Descent with modification. This is what Darwin called evolution.
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.
What are the structurall and biochemical similarities of animalsand all living organisms?
The structural and biochemical similarities among living organisms are best explained by Darwin's conclusion: Living organisms evolved through a gradual modification of earlier forms --- descent from a common ancestor.
New generations are better suited to the environment than the first generation what is this called?

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 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."
