Hybrids
Description
In the animal kingdom, rare instances of interbreeding between closely related species occasionally occur, resulting in offspring known as hybrids. Discover why these animals are often sterile, the biological barriers that prevent different species from reproducing together, and the role that mixed genetic makeup plays in this fascinating process.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
