There are several techniques that can be used to determine possible relationships among organisms based on their fossil remains. These techniques include:
- Morphological Analysis: This involves examining the physical characteristics of the organisms, such as the shape and size of their bones, to determine their possible relationships.
- Biochemical Analysis: This involves analyzing the chemical makeup of the organisms, such as the composition of their proteins or DNA, to determine their evolutionary relationships.
- Stratigraphy: This involves examining the layer of sediment in which the fossil was found, as well as the age of the sediment, to determine the age of the fossil and its possible relationships to other organisms.
- Paleobiogeography: This involves examining the geographic distribution of the organisms and their fossil remains to determine their possible relationships and evolution.
By applying these techniques, you can determine possible relationships among the three organisms you have discovered and understand their evolutionary history.
