History

Domestic hamsters are derived from one female wild golden hamster (Mesocricetus auratus) and her 12 offspring. The original stock was collected by Dr. Aharoni in northern Syria in 1930. After setting up a breeding programme in Jerusalem, he sent a number of hamsters to the UK in 1931 and some to the USA in 1938, for use in laboratories. They were introduced into the pet trade in 1945.

 

Life span

Hamsters are short lived and usually only live for 18-24 months in the wild and up to three years in captivity.

 

Distribution and Habitat in the wild

The golden hamster is found in the steppe regions of North West Syria.

The Scrotum Is Nuts

 

 

Why are testicles kept in a vulnerable dangling sac? It’s not why you think.

 

 

 

 

Soccer fans call it brave goalkeeping, the act of springing into a star shape in front of an attacker who is about to kick the ball as hard as possible toward the goal. As I shuffled from the field, bent forward, eyes watering, waiting for the excruciating whack of pain in my crotch to metamorphose into a gut-wrenching ache, I thought only stupid goalkeeping. But after the fourth customary slap on the back from a teammate chortling, “Hope you never wanted kids, pal,” I thought only stupid, stupid testicles.

 

Natural selection has sculpted the mammalian forelimb into horses’ front legs, dolphins’ fins, bats’ wings, and my soccer ball-catching hands. Why, on the path from the primordial soup to us curious hairless apes, did evolution house the essential male reproductive organs in an exposed sac? It's like a bank deciding against a vault and keeping its money in a tent on the sidewalk.

 

Some of you may be thinking that there is a simple answer: temperature. This arrangement evolved to keep them cool. I thought so, too, and assumed that a quick glimpse at the scientific literature would reveal the biological reasons and I’d move on. But what I found was that the small band of scientists who have dedicated their professional time to pondering the scrotum’s existence are starkly divided over this so-called cooling hypothesis.

 

Reams of data show that scrotal sperm factories, including our own, work best a few degrees below core body temperature. The problem is, this doesn’t prove cooling was the reason that testicles originally descended. It’s a straight-up chicken-and-egg situation—did testicles leave the kitchen because they couldn't stand the heat, or do they work best in the cold because they had to leave the body?

 

Vital organs that work optimally at 98.5 degrees Fahrenheit get bony protection: My brain and liver are shielded by skull and ribs, and my girlfriend’s ovaries are defended by her pelvis. Forgoing skeletal protection is dangerous. Each year, thousands of men go to the hospital with ruptured testes or torsions caused by having this essential organ suspended chandelierlike on a flexible twine of tubes and cords. But having exposed testicles as an adult is not even the most dangerous aspect of our reproductive organs’ arrangement.

 

The developmental journey to the scrotum is treacherous. At eight weeks of development, a human fetus has two unisex structures that will become either testicles or ovaries. In girls, they don't stray far from this starting point up by the kidneys. But in boys, the nascent gonads make a seven-week voyage across the abdomen on a pulley system of muscles and ligaments. They then sit for a few weeks before coordinated waves of muscular contractions force them out through the inguinal canal.

 

The complexity of this journey means that it frequently goes wrong. About 3 percent of male infants are born with undescended testicles, and although often this eventually self-corrects, it persists in 1 percent of 1-year-old boys and typically leads to infertility.

I have a bad memory, a very bad memory. All to many things I forget after a short period of time and other things (usually of interest) I remember for a long. On a very rare occasion I hear/read/see something of little interest that I just can't forget. It was in 7th or 8th grade, over 50 years ago that heard or read Newtons Law of Universal Gravitation and never forgot it. I can quote the whole thing without any hesitation. I can go years without thinking about it and can still recite it. Not really science I know, just interesting. Newtons Law of Universal Gravitation. :kook:
