Answer:
1 HOX genes are very similar in all animals.
3 Many species share much the same DNA.
4 Plant and animal cells have almost all of the same structures.
Step-by-step explanation:
Evolution corresponds to the process of modification and adaptation of species over time. The current diversity and genetic similarity of living beings is the result of processes of transformation and adaptation of species to various environments, constituting biological evolution. As evidence of this evolution, we can mention:
- HOX genes are very similar in all animals: Hox genes encode transcription factors that define cellular identities along the major and minor axes of the body. Its coordinated expression in space and time is fundamental for embryonic modeling. These genes control the development and positional differentiation of cells in the embryo, and their disposition along the chromosome collinear to the parts of the embryo they will regulate. They are present in many different animals representing a huge source of evolutionary change.
- Many species share much the same DNA: All living things have DNA molecules that encode all genetic information. Among living things there are similarities and sharing of parts of DNA. This is strong evidence of species evolution. An example of this is the similarity between humans and chimpanzees.
- Plant and animal cells have almost all of the same structures: Although there are some differences, plant and animal cells share almost all cell structures. This is a strong indication of how life has evolved on our planet.
