If new evidence emerges of animals' abilities to feel and process what is going on around them, could that mean they are, in fact, conscious? We now know that bees can count, recognise human faces and learn how to use tools. Prof Lars Chittka of Queen Mary University of London has worked on many of the major studies of bee intelligence. If bees are that intelligent, maybe they can think and feel something, which are the building blocks of consciousness," he says. Prof Chittka's experiments showed that bees would modify their behaviour following a traumatic incident and seemed to be able to play, rolling small wooden balls, which he says they appeared to enjoy as an activity. A government review led by Prof Birch in 2021 assessed 300 scientific studies on the sentience of decapods and Cephalopods, which include octopus, squid, and cuttlefish. Prof Birch's team found that there was strong evidence that these creatures were sentient in that they could experience feelings of pain, pleasure, thirst, hunger, warmth, joy, comfort and excitement. The conclusions led to the government including these creatures into its Animal Welfare (Sentience) Act in 2022. Prof [Kristin] Andrews was among the prime movers of the New York Declaration on Animal Consciousness signed earlier this year, which has so far been signed by 286 researchers. The short four paragraph declaration states that it is "irresponsible" to ignore the possibility of animal consciousness.
