Division among species

Human beings often questions about the world such as how the world was created, and

have doubts about religions even thought they believe in one. The theory of Darwinism, creates a

new idea of how human beings were created, and how they came to the stage they are in right

now. In the Richard Dawkins book, River out of Eden, introduces a idea of Digital River,

where species creates many branches of many kind. In this book, Dawkins explains the digital

river by using the illustration of speciation, explanation for the “long good bye”, and speciation

from the reptiles.

To begin with, the digital river, term that humans created for the explanation of the

speciation, describes the whole cycle of process that occur among the living creatures over time.

In order for creatures in this world to survive, they need to adapt to the environment they are in.

Dawkins states that “to be good at surviving, a gene must be good at working together with the

other genes in the same species-the same river. To survive in the long run, a gene must be a good

companion.”(5) Thus saying that among their own kinds, any certain kind of species has to be in

a good shape and needs the competitive attitude towards their kind. For example, when lions

hunt zebras, they need strong leg muscles and swift movement in order to get the prey in one

shot. Usually, in order to achieve this status, lions need to acquire good genes from their

ancestors. If they do not have the skills to hunt, they will not be able to survive, resulting only

the fastest and quickest lions to survive in the cycle.

Dawkins also states the idea of the “long goodbye”, relates to the digital river. The “long

good bye” is a status when animals of similar kinds cannot have sexual intercourse anymore. The

book states “nobody doubts that the most important ingredient is accidental geographical

separation. For example,...
