dulu Rumput adalah Santapan Makan Malam Manusia Purba
VIVAnews - Sebuah studi baru menemukan bahwa manusia purba memilih rumput menjadi santapan makan malamnya. Melansir NPR, 5
Juni 2013, temuan baru itu didapat tim peneliti dari University of
Utah, Amerika Serikat, setelah bertahun-bertahun meneliti fosil gigi
manusia purba Australopithecus.
"Kami menemukan isotop karbon
dengan kadar tertentu yang tersimpan di gigi manusia purba itu," kata
Thure Cerling, ahli geokimia dari University of Utah, AS.
Dia
menambahkan, temuan dari gigi itu mengungkapkan bahwa 3,5 juta tahun
lampau, manusia purba melakukan perubahan perilaku makannya. "Manusia
purba telah beralih memakan daun dan rumput," ungkapnya.
Temuan
terbaru ini sangat bertentangan dengan penelitian sebelumnya, yang
menyatakan manusia purba sangat suka memakan daging. Temuan baru ini pun
menuai perdebatan di kalangan ahli antropologi.
Cerling pun
mengakui, isotop karbon yang ditemukan pada manusia purba
Australopithecus, bisa saja didapatkan setelah memakan kijang yang sudah
terlebih dahulu memakan daun dan rumput.
"Tapi, temuan ini tetap
menarik. Perubahan pola makan ini telah memberi pengaruh kuat dalam
evolusi manusia," ujar Cerling. "Perubahan pola makan erat kaitannya
dengan evolusi ukuran otak dan kecerdasan manusia purba."

The prostate gland is central to the portion of a male's reproductive system. It secretes fluids that assisted in the transportation and activation of sperm.

This condition is treated by making use of antibiotics or non-steroid anti-inflammatory drugs (NSAIDs) to relieve the swelling.
Chronic bacterial prostatitis can be a condition of a particular defect inside the gland and also the persistence presence of bacteria in the urinary tract. It can be due to trauma towards the urinary tract or by infections received from the rest from the body. A patient can experience testicular pain, back pains and urination problems. Although it is uncommon, it could be treated by removal with the prostate defect as well as the utilization antibiotics and NSAIDs to treat the soreness.
Non-bacterial prostatitis makes up about approximately 90% of all prostatitis cases; however, researchers have not even to create the sources of these conditions. Some researchers feel that chronic non-bacterial prostatitis occur because of unknown infectious agents while other believe that intensive exercise and heavy lifting can cause these infections.
