The main type of evidence the scientists used is fossils.
Palaeontologists study plants and animals that existed in the geologic past. To do so, they use fossils and try to determine an organism's evolution and relationship with the environment and other organisms. In this example, palaeontologists used fossils from ancient horses that have gone extinct and try to decipher their evolutionary path. Recognising the evolutionary steps of the ancient horses will make it possible to compare them to the modern horses.
Shrubs and trees regrow quickly in an area that has been burned during a forest fire.
Algae,grasses, and other small plants grow on newly exposed rock over a long period of time.
Answer:
A novel GPCR role in regulating cell density sensing. Homeostasis modulation (e.g., water balance). Involved in growth and metastasis of some types of tumors. Used in the endocrine system for peptide and amino-acid derivative hormones that bind to GCPRs on the cell membrane of a target cell.
