A recent study of ancient and modern elephants has  come up with the unexpected conclusion that the African elephant is divided into two distinct (不同的) species
The discovery was made by researchers at York and Harvard universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephants—the Asian elephant, African forest elephant and African savanna elephant
Once they obtained DNA sequences (序列) from two fossils (化石)，mammoths and mastodons， the team compared them with DNA from modern elephants. They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths.
The scientists used detailed genetic analysis to prove that the African savanna elephants and the African forest elephants have been distinct species for several million years. The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths. This result amazed all the scientists.
There has long been debate in the scientific community that the two might be separate species but this is the most convincing scientific evidence so far that they are indeed different species.
Previously, many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species despite the elephants’ significant size differences. The savanna elephant has an average shoulder height of 3.5metres while the forest elephant has an average shoulder height of 2.5metres. The savanna elephant weighs between six and seven tons, roughly double the weight of the forest elephant. But the fact that they look so different does not necessarily mean they are different species. However, the proof lay in the analysis of the DNA.
Alfred Roca, assistant professor in the department of Animal Sciences at the University of Minois, said, “We now have to treat the forest and savanna elephants as two different units for conservation purpose. Since 1950 all African elephants have been conserved as one species. Now that we know the forest and savanna elephants are two very distinct animals, the forest elephant should become a bigger priority (优先)for conservation purpose .”
【小题1】One of the fossils studied by the researchers is that of ________.

We hear with our ears, right? Yes, but scientists have known for years that we also hear with our eyes. In a study published in 1976, researchers found that people combined both auditory cues(听力提示) and visual ones，like mouth and face movements, when they heard speech.
A new study that looks at a different set of sensory cues adds to a growing body of evidence that suggests such combination is natural. In a paper, Bryan Gick and Donald Derrick report that people can hear with their skin.
The researchers had volunteers listen to spoken syllables. Meanwhile, they connected the volunteers to a device that would blow a tiny puff (气流) of air onto the skin of their hands or necks. The syllables included “ba” and “pa”, which produce brief puffs from the mouth when spoken, and “da” and “ta,” which do not produce puffs. They found that when listeners heard “da” or “ta” while a puff of air was blown onto their skin, they considered the sounds as “ba” or “pa”.
Dr. Gick said the findings were similar to those from the 1976 study, in which visual cues defeated auditory ones — volunteers listened to one syllable but thought it another because they were watching a video of mouth movements corresponding to the second syllable. In his study，he said，cues from sensory receivers on the skin defeated the ears as well. “Our skin is doing the hearing for us,” he said.
Dr. Gick noted that it would normally be rare that someone actually sensed a puff of air produced by another, although people might occasionally sense their own puffs. “What’s so persuasive about this particular effect,” he added. “is that people are picking up on this information that they don’t know they are using.” That supports the idea that combining different sensory cues is natural.
Dr. Gick said the finding also suggested that other sensory cues might be at work in speech perception(知觉) — that, as he put it, “we are these fantastic perception machines that take in all the information available to us and combine it faultlessly.”
【小题1】“Da” or “ta” were considered as “ba” or “pa” when __________.
