A team from the University of Cambridge did the following experiment: they placed a group of cows in a pen where there was a lever. If the animals squeezed it correctly, they could go out into a field full of rich food. The researchers saw signs of satisfaction when the cows understood the mechanism. Their heart rate increased and the chances that they would jump into food increased. This and other works have led scientists to consider that animals have feelings that should be respected . This discipline is one of the most interesting and important fields in all of biology, and researchers are eager to find answers.
Do animals have feelings?
When hyenas lived in the Arctic
These animals crossed from Asia to America through the Bering Bridge during the Ice Age.
Can an alligator have feathers?
If alligators and crocodiles have the genes that allow them to form feathers, why aren't they feathered?
We were able to start breeding animals 2000 years earlier than previously thought
This is demonstrated by remains of charred manure that are 13,000 years old.
They discover that more than 50 animals that we thought were mute can speak
Acoustic communication plays a fundamental role in aspects such as partner attraction and a number of other behaviors. The finding takes us back to 407 million years ago.
Hairy snail found in 99-million-year-old chunk of amber
How come they had hair? Its utility? Scientists think that Mesozoic land snails probably benefited from their fine hairs. Would it make them more attractive?
