Combining sentences by addition involves connecting sentence elements with punctuation (comma, semicolon) and either coordinate or subordinate conjunctions. In the following example, three separate sentences can be combined.
The multiple layers of fossil-bearing deposits indicate that early humans first took shelter in the cave 460,000 years ago.
The last of them did not abandon the site until 230,000 years ago.
They were forced out by the filling of the cave with rubble and sediment.
In this case, combining requires no changes to the sentences themselves. The original article about "Peking Man" in Scientific American combined them by adding the coordinate conjunction "and" along with a comma and the subordinate conjunction "when."
The multiple layers of fossil-bearing deposits indicate that early men first took shelter in the cave 460,000 years ago, and the last of them did not abandon the site until 230,000 years ago, when they were forced out by the filling of the cave with rubble and sediment.
