1 Answer
Scientists estimate there are a million species that exist today, yet over 99% that ever existed are extinct.
Explanation:
"However" is a conjunctive adverb, just like "therefore," "meanwhile," and "otherwise." To connect two clauses, you must use a semicolon after the first clause and a comma after the conjunctive adverb:
subject/verb; (conjunctive adverb), subject/verb.
On the other hand, "yet" is a simple conjunction just like "and" or "or." It only requires a comma after the first clause.
In the question, there is only a comma, so you would use yet:
Scientists estimate there are a million species that exist today, yet over 99% that ever existed are extinct.
