Isizalwane seZimbabwe eJohannesburg, uMnu. Lebani Nkomazana, uthi kuyamangalisa ukuthi yindaba uTsvangirai engangcwatshwanga emathuneni amaqhawe esizwe eHeroes Acre. Uma u ukulandwa IDM ukuqhuma ke kakhulu ukwazi ukuthi ithimba IDM usethule inguqulo entsha e njalo ngenyanga konyaka 2017 futhi iningi lokhu ngcono kwaba okuhlobene izimbungulu lapho abasebenzisi zabo ku-Firefox bekaqalene. IN version 6.29, baye phambili fixed izimbungulu kuhlanganise nokuthi angase ukulanda amafayela nge-VPN uxhumano kanye amaseva proxy ngaphandle kokulahlekelwa original isivinini ukulandwa. Zinengi izinto abantu abathi kumele sibelazo empilweni. Kodwa iBhayibhili lithi “suthisekani ngalokho elilakho.” Kumele senzeni ukuze sisuthiseke? The teeth of fossil gomphotheres and elephants preserve a signal of their diets. The ratio of different isotopes of carbon in the tooth enamel shows whether a particular individual was focusing more on browsing on leaves or eating grass. The grasslands of Africa first began to spread around 10 million years ago and isotope analysis reveals that late gomphotheres and early elephants switched to eating mainly grass around eight million years ago. In elephants, this switch is reflected in another change to their chewing teeth, which became three times as tall, with a proliferation of enamel ridges. But these adaptations to an abrasive diet appeared around five million years ago, three million years after that switch from soft leaves to tough grasses. With the degree of resolution we can achieve when looking far back into the past, it’s often difficult to know what came first – a change in behaviour or in anatomy. But in this case, it’s very clear: the changes to teeth lagged millions of year after the change in diet.
