The reverse effect happens after training on forms.
The size of the brain is a frequent topic of study within the fields of anatomy, biological anthropology, animal science and evolution.Measuring brain size and cranial capacity is relevant both to humans and other animals, and can be done by weight or volume via MRI scans, by skull volume, or by neuroimaging intelligence testing.
These results have been backed up by the Human-Elephant Learning Project which studies elephant intelligence. [58] An elephant named Shanthi at the National Zoo in Washington D.C. displayed the ability to play the harmonica and various horn instruments. She reportedly always ended her songs with a crescendo.

[15] A subspecies has a name composed of three parts (a trinomial name or trinomen): generic name + specific name + subspecific name; for example Canis lupus italicus. As there is only one possible rank ...
