Over the centuries, we believed that animals do not have an intelligence or the ability of logical thinking and learning.It was believed that their lives are just guided by "Instinct". However as expected there is no consensus about this among scientists due to the difficulty in designing the experiments which can be used generally to assess the intelligence among various species making the interpretation very difficult.
Every organism has some kind of blue print which it knows since birth and other information for survival is gained by experience either of their own and learnt from those of parents and relatives. Nature has given each and every animal some kind of power necessary for survival.
We all have heard the story of Abhimanyu who learnt the art of breaking into "Chakravyuh" while in Subhadra's womb and modern science also confirms that human babies along with other mammals have womb with a view, i.e. a sound view and babies of humans as well as other animals can recognize their mother's voice and can differentiate that with other sounds and also respond to the various events experienced by their mother. This ability is especially vital for survival in the wild for animals especially located at bottom or middle of the food-chain. e.g mallard ducklings cant survive without their mother and start following their mother everywhere immediately after they hatch. The experiments showed that the ducklings followed a box containing recorded sound of their mother instead of another duck, which shows that the mother's sound is more important than her appearance which is understandable in the night where the vision would be limited.This certainly doesnt mean that they cant differentiate between shapes or so,but the sound is just more important for their initial survival.
Similar thing happens in a Ring-billed gull colony...In a single colony, there would be thousands of birds and sound is the only effective way to avoid getting lost and get attention of parents to get food as their would be thousands of hatching at same time. To confirm this, some experiments were carried on these species in which one clutch of eggs was exposed to maternal feeding call sounds while another clutch was incubated in silence. After hatching the chicks which have heard their mother's calls while in eggs, pecked at her beak encouraging her to regurgitate the food while the other group didnt peck at their mother at all and certainly had little chance of survival in the wild. These birds are extremely territorial and a chick lost from its parents would certainly be killed by other gulls. Hence the hearing mother's call while in egg, also has a survival value.
We know about our surroundings through our vision which we obviously learn from experience and is recorded in our memory due to which we can exactly find our home. I was astonished to find that same thing happens in case of animals of each shape and size. A very insignificant looking digger wasp,which makes its nest burrowing the soil has good understanding and memory of its surrounding. In case of one digger wasp, scientists placed artificial flowers around her nesting hole with her nest at the centre. The wasp came out and flew around before moving way from the nest; while it was away scientists replaced the flowers to adjoining site. To their total astonishment, when fly came back, it went straight to the centre of those flowers to search its nest.
All these things certainly show that all animals are similar to humans and every animal possesses some sort of intelligence and have a sense of their surroundings and typical survival skills. All these organisms also learn the life's lessons for survival and growth, similar to us where we learn in schools and our surroundings.
