The Dinosaur Feather

his team had no scientific grounds on which to base their argument, he went on, as fossils and recognised systems of taxonomy confirmed the close relationship between birds and dinosaurs.
    ‘And yet they persist.’ Dr Tybjerg fixed Anna’s gaze, and his eyes narrowed. ‘Why?’
    Anna sat with the coracoids and tried to work out which one would fit into the sternum.
    Dr Tybjerg seemed to approve of her choice by passing her a scapula. As he gave her the bone, he looked at her urgently and prompted, ‘Two hundred and eighty-six apomorphies.’
    ‘Sorry?’
    ‘They dismiss 286 apomorphies.’
    Anna gulped. Now what was an apomorphy again? Tybjerg twirled a small, sharp bone between his fingers.
    ‘You need to review all of their arguments and all of ours,’ he said. ‘Pair them up and go through them. Once and for all. Together we will wipe the floor with him.’ Coming from Tybjerg, this expression sounded odd. Anna looked out at the University Park.
    ‘We’ll publish a small book,’ he added. ‘A manifesto of some kind. The ultimate proof.’ He stared triumphantly into the air.
    Anna had got up to leave when Dr Tybjerg suddenly said, ‘By the way . . .’ and tossed a key across the table. It seemed as if it had slipped out of his sleeve. Anna caught it and, without looking at her, Dr Tybjerg said:
    ‘I did
not
just give you a master key.’
    Anna quickly pocketed the key and said:
    ‘No, you certainly didn’t.’
    Dr Tybjerg had entrusted her with a key which was normally forbidden to students. Now every door was open to her.
    When Anna left the Museum, her curiosity had been rekindled. She asked Johannes about Tybjerg.
    ‘A lot of people don’t like him,’ was his immediate reaction.
    ‘Why?’ Anna was genuinely surprised. Johannes suddenly looked as if he had second thoughts.
    ‘I don’t want to be seen as a telltale,’ he said, eventually.
    ‘For God’s sake, Johannes, give me a break,’ Anna exclaimed.
    He thought it over. ‘Okay,’ he said. ‘But I’ll make it brief. Word has it Tybjerg is an insanely gifted scientist. He was hired by the museum to keep track of their collections whenhe was still a schoolboy. He’s supposed to have a photographic memory, but he’s socially inept and really quite unpopular. For years Tybjerg and Helland have constituted some sort of team . . .’ He wrinkled his nose. ‘When he was younger, he taught undergraduates. In fact, he used to teach me. But there were complaints.’
    ‘Why?’
    ‘He can’t teach,’ Johannes declared.
    ‘That’s weird,’ she said. ‘I’ve just spent all afternoon with him and I thought he explained things really well.’
    ‘Not to a classroom full of students. He gets nervous and he drones on as if he were reading aloud from some long, convoluted text he knows by heart. I think he’s a bit doolally, I mean, seriously. They only keep him on because he knows everything there is to know about the Vertebrate Collection. More than anyone in the whole world. It’s like hiring someone with autism to look after a vast record collection. He knows where everything is and what it’s called. But they would never offer him tenure. To be employed by the University of Copenhagen, you have to be able to teach.’ He paused before he added: ‘Dr Tybjerg is weirder than most.’
    Anna rested her head on her keyboard.
    ‘Lucky me, or what?’
    ‘What do you mean?’
    ‘One of my supervisors is useless and the other one is a weirdo.’
    ‘Don’t start all that again,’ Johannes said. ‘We’ve already been there. Helland’s all right.’
    ‘I’m just saying.’
    ‘Yes, and I would rather you didn’t.’

     
    To begin with, every word and every scientific argument in the controversy about the origin of birds were watertight and unassailable. Anna accepted that, as her starting point, she probably had to take Helland’s and Tybjerg’s positions at face value in order to even begin to understand the vast network of scientific implications; later she could form her own opinion. However, she honestly couldn’t see why Helland and Tybjerg were right, and Freeman, according to them, was wrong.
    ‘Birds are present-day dinosaurs,’ she wrote on a sheet of paper, followed by: ‘Birds are direct descendants of dinosaurs.’ Then she drew two heads, which bore some resemblance to Tybjerg and Helland, on the paper and pinned it up on the wall. She took another sheet, drew another head – supposed to be Freeman’s
