Documentaries about animals being used for medical tests have always thrust a sense of guilt in me as a human being.
I love animals, birds and all natural creations, like a rose, butterfly or that chubby girl.
Just started reading a book “10 Questions Science Can't Answer (Yet)” by Michael Hanlon. Awesome boss. Some points he has argued in defence of animals can leave anti-animal humans defenceless.
There is an example about crows’ intelligence.
In the BBC television series Life of Birds, a footage was shown in which crows in Japan dropped hard-shelled nuts onto the road at a pedestrian crossing. After waiting first for the nut to be cracked open by a passing car and then for the traffic to be stopped when a pedestrian pushed the button, the crows would land to retrieve their nuts.
There is another story also about crow’s brainpower.
A crow called Betty starred in Science2 magazine after she had learned to fashion a hook out of a piece of wire and use this tool to fish food out of a glass pipe. That took scientists aback as this level of tool making skill has never been observed even in chimpanzees.
I stop here to save your time. Will continue this post later.
