sodium amytal test: anesthetize one hemisphere and check for language function dichotic listening test: report more digits heard by dominant half functional brain imaging: fMRI or PET used to see which half is active when performing a language test
The process of change by which new species develop from preexisting species over time? The process by which species change over time is evolution. The process by which new species develop from preexisting species over time is evolution.
Species hypothesized to have the same ancestors are placed in one genus, based on similarities. The similarity of species is judged based on comparison of physical attributes, and where available, their DNA sequences.All species are given a two-part name, a binomial name, or just binomial.The first part of a binomial is the generic name, the genus to which the species belongs.eproductive species. Two organisms that are able to reproduce naturally to produce fertile offspring of both sexes. Organisms that can reproduce but almost always make infertile hybrids of at least one sex, such as a mule, hinny or F1 male cattalo are not considered to be the same species.
