Species
A species is a group of living beings or organisms having common ancestry and therefore significant genetic similarities in common. The boundary between one species and another is the ability to mate and produce offspring. [1] A tiger and a clam are different species, because they cannot mate. A German Shepard and a Beagle can mate, because they are different breeds within one species.
The origin of species
Most Americans believe that God created the different species of plants and animals in six days of Creation (Genesis chapter 1). Religious faith on this is divided into Young Earth Creationism (the process started less than 10,000 years ago and took a short time) and Old Earth Creationism (the process began hundreds of millions of years ago and took millions of years).
Charles Darwin wrote The Origin of Species 167 years ago, hoping to account for the diversity of plant and animal life with an entirely naturalistic explanation (see Theory of evolution).
