Explanation
When you're looking for exact replicas, don't waste your time on snowflakes or fingerprints; no two are identical, or exactly the same. Great mind may think alike, but they'll never be identical. Twins, on the other hand, very well may be — if they've come from the same split embryo that is. It makes sense then, that the word identical has linguistic roots in the Latin word idem, meaning "the same."
