nuremberg is working together with 12 other european zoos that are all conducting the same tests. data is being gathered on more than 100 different dolphins. at regular check ups the animals are weighed in and their eyes are examined. by no abnormality detected. the researchers also regularly document any new scratches and compare them with previous check ups. these rake marks as they're called reveal quite a bit about a dolphins well being you know if you go. back on specific bodies and right mark you really need to take a close look at these right box quite a lot of them or not at all both can be indicators of social behavior. dolphins are highly sociable animals and interactions are natural whether they are positive or sometimes negative and he is right mocks a very telling rate if an animal never has new scratches this can show that it's not part of the group it's isolated. from your physician or line on going to god and you don't have an animal has lots of new scratches week after week of a months then that shows that something isn't quite right within the group social struct

with the dolphins the nuremberg zoo was a step further it's currently developing a procedure with more than 28 different parameters that help to measure animal wellbeing systematically the animal's appearance is also taken into account. just as it should be no dent behind the head. or often and there isn't a reamer round the years making them bend even with its inverted 9 c. taking really good. effect on. 198 so we have to check that again we'll look in a minute. and do another way. the experts are collecting data designed to be as objective as possible. you can send up to me followed by genny straight after every single animal is checked regularly and a list of measurements is carefully worked through the aim is to reflect each creature's condition as precisely as possible again today to see even turns in decent tool is this really contains every indicator every aspect that we think needs to be assessed. then we corroborate the information so that it can be objectively evaluated. the idea is that we proceed objectively step by step assessing the state of health the behavior but also t

i think it really is at the zoo in nuremberg sesame seem pretty contained especially since the recent arrival of a new baby. the similarities between apes and humans are pretty striking. a deal in guyana sent in a question about that. how closely related are we humans and chimpanzees. very closely some 98.5 percent of our d.n.a. base pairs are identical based on average findings from a range of analytical methods. and our genetic match with gorillas is just one quarter of a percentage point less than that. orangutan has branched off from our common family tree other 2 earlier but they still share 1007 percent of their d.n.a. with us so how do we explain the huge difference between humans and apes. some primates can scale trees in the rain forest. while another species exploits other planets. the human genome contains some 3000000000 base pairs of which just 40000000 differ from those of chimpanzees but this vital difference means that certain proteins in apes have other structures and possibly other functions in the body. but for all the differences there are also many similarities us
