Chapter 2

Chapter 2 was equally interesting as chapter 1. In chapter 2, the author went into a bigger depth of the forming of limbs in the fishes. The author provided the drawing of an Acanthostega, which was the earliest fish to develop recognizable limbs. The drawing shows a series of fins, then shows the Acanthostega's, which is not a fin, but not a hand. However, the Acanthostega's drawing did show bones of fingers, fingers that are on our hands today. The figure which contained the fingers of Acanthostega's showed a visual process of the fishes' evolution. The early phase of the drawing showed the zebrafish, with no recognizable fingers, and with a large amount of webbing and bones at the center. Then, in the middle it showed the Eusthenopteron. The Eusthenopteron started to gain bones to fill in the gaps between the webbing and started to create an early model of our upper arm and forearm. The author helps the readers concentrate on the main focus through the usage of visual affects. The visuals also help readers to convey the idea that the author is trying to say. Hence, it makes the book easy to understand and comprehend. My last question from the Chapter 1 Blog has been answered. There was that specific moment where fishes walked on land and gained limbs. The Acanthostega was the specific moment where fishes gained limbs.
