Are you dense?
Here is the Boxer of Quirinal, a statue that dates back to approximately 300 B.C.
UK weightlifters a few decades before AAS had even been conceived:
Reaching one's physical peak is hardly new or unnatural. A lean, well-muscled physique grants humans more speed and agility for use in combat, hunting, and evasion. It is precisely why peoples like the Turks, and Akans are naturally well-muscled, as they historically didn't require extra fat tissue to fuel themselves over long periods of malnutrition and cold weather, but did need lean physiques to remain competitive.
Conversely, people in the Caucasus region, especially those of modern Asian ethnicity derive from harsher conditions requiring more fat-oriented physiques. Still evident to this day, especially within the colder climates of the Korean peninsula and Japan.
People who shed excess bodyfat are hardly unnatural. It is not necessary to today's living, and being lean can offer a plethora of athletic and lifestyle advantages in today's adaptive society and model of biological interaction.
TL;DR-you are a muppet.
