Allopatric speciation, also referred to as geographic speciation, is a method of the formation of new species due to isolation of the species from one another through geographic means.
The first step in this process is geographic isolation, which means that the original population is divided into two groups due to geographical reasons such as movement of continents or formation of water bodies.
Next, the species are subjected to different selection pressures due to their different environments. Eventually, the gene pool becomes very different for the two species due to the different selection pressures and because they are not allowed to mix.
Finally, after enough time passes, speciation occurs, which means that the two populations cannot breed to form fertile offspring.
Answer: tissue
Explanation:
All living organisms are made up of one or more cells. For example, unicellular organisms, such as amoebas, are made up of only one cell. Multicellular organisms, such as human beings, are made up of many cells. And cells in complex multicellular organisms are organized into tissues, which refers to similar groups of cells that work together on a specific task.
