Question

collect information about the envolution of the brain of vertebrate​

Answer 1

Answer:

1)The structure of all vertebrate brains is basically the same. At the same time, during the course of evolution, the vertebrate brain has undergone changes, and become more effective. In so-called 'lower' animals, most or all of the brain structure is inherited, and therefore their behaviour is mostly instinctive.

2)The area of the brain with the greatest amount of recent evolutionary change is called the neocortex. In reptiles and fish, this area is called the pallium, and is smaller and simpler relative to body mass than what is found in mammals. According to research, the cerebrum first developed about 200 million years ago.

3)Endocasts of Homo erectus (left) and Homo sapiens (right) illustrate rapid increase in brain size. As early humans faced new environmental challenges and evolved bigger bodies, they evolved larger and more complex brains. Large, complex brains can process and store a lot of information.

4)During the evolution of vertebrates, the cardiovascular system has undergone marked anatomical and functional changes. ... A heart with a single trabeculated ventricle and a single atrium evolved later among fish where blood first perfuses the gills and then the systemic vasculature

5)The peripheral nervous system, composed of nerves that run to all parts of the body, transmits information to and from the central nervous system. The vertebrate brain is divided into three main divisions: the forebrain, the midbrain, and the hindbrain.

i hope it helpfull to you
