Unusual Discovery in South African Orchard

Is there a faster, cheaper method to pick  sweetest oranges in the orchard? Ask a baboon.

A group of baboons in South Africa is being recognized as capable of sniffing out a new, sweeter variety of orange. Their speed and accuracy at gobbling up quickly ripening fruit has led to a discovery of what is believed to be a new type of tangerine.

Alwyn van der Merwe, production director of ALG Estates near Citrusdal, South Africa, said the farm noticed that baboons that come down to the farm from nearby mountains each year always went to feed from a particular tree among the thousands in the orchards. The animals stripped the tree clean of fruit well before others in the orchard were in season, he said.

“At closer inspection we discovered that the brix [sweetness grade] of this particular minneola, a soft citrus variety, was much higher than the rest of the orchard and that it started bearing fruit at least three weeks earlier than expected,” van der Merwe said.

” It was clearly a case of a spontaneous mutation in the orchard, which would have gone unnoticed were it not for the baboons,” van der Merwe is quoted as saying.

Growers have begun grafting shoots from the baboon’s favorite tree onto other root stock and hope to be producing large quantities of the sweeter minneola in a few years.

And he knows the baboons will likely be the first customers.

“I’m sure they will have a feast one day when we produce a whole orchard of these early sweet minneolas,” he said.

One for two: Africa has two species of elephants

If at high school biology you were taught that there are two species of elephants — the African and the Asian —it’s time to forget that.

A new research shows that the “African elephant” is actually two species. These two species are as evolutionarily different as goat and sheep are from one another. It’s a surprising degree of divergence that has just been reported.

The study, published in this week’s issue of the journal PLoS Biology was conducted by teams from Harvard, the University of Illinois and the University of York in Britain. The evolutionary divergence was identified by analyzing the DNA of the living elephant species and two of their extinct evolutionary cousins, the woolly mammoth and mastodon.

The study suggests the species separated several million years ago, about the same time that humans diverged from chimps.

The forest elephant is smaller, and is sometimes referred to as the “dwarf African elephant,” standing at about 8.2 feet high compared with the savanna elephant’s 11.5 feet, and weighing about half as much. The forest elephant also has straighter tusks and oval-shaped ears.

The savanna elephant weighs between 6 and 7 tons, roughly double the weight of the forest elephant.

The African elephant is listed as endangered by the U.S. Endangered Species Act, and splitting the population into two different species places the forest elephant in much more dreadful category.
