The person – a product of evolution?! Whether everything is so clear here?!

Rats communicate among themselves with very large number of various signals in the ultrasonic range.
Rats are capable to think, as has shown a number of experiments, no worse than primates.
Rats are capable to understand value of a number of words and to use them on sense according to a situation. Rats are also capable to copy the human speech.
Rats can generalize a number of situations and use the abstract forms, matured in their heads.
Rats are also capable to deduce the general rules of behavior on the basis of the accumulated life experience and to use them for the solution of the tasks with which they weren't encounter yet.
Rats even possess rudiments of self-awareness, in particular, being able to estimate adequately correctness of own decisions made in ambiguous situations, increasing thereby probability of correctness of own actions further.
On the other hand, the rat brain increases in a size quicker than new neurons are got. Therefore, the larger individuals possess smaller number of neurons on gram of neural fabric, than small individuals while one gram of neural fabric of the large primates and the small primates contains identical amount of neurons. In other words, the brain of primates is constructed on the most economic use of space.
As a result, for example, the brain of a rat with 86 billion neurons (as at the person) would weigh 35 kg.
Regarding dolphins following can be noted.
The brain of dolphins is developing about 47 million years. The ratio of its weight to the size of the body corresponds only to similar ratio at the person.
Reasonableness dolphins reaches a high degree, as evidenced by the possession of language with the dictionary volume 1012, and the number of signals produced by them in the normal mode is about 14 thousand: it is the same amount as at people in everyday life. The signal of a dolphin carries more meaning than the separate word.
