15. Biodiversity is effected by genetics since genetics can determine there would be a variety of life in habitat or ecosystem.
16. Genetics/evolution can cause a new species to evolve because of how many times genetics is changed. Evolution can cause new traits to occur causing a new species to be created.
17. Embryos can help scientists to understand evolution better since an early stage of development of a multicellular diploid eukaryotic organism is represented and scientists can observe the development of the organism and better understand evolution better.
