WebIn order to determine which organisms in a group are most closely related, we need to use different types of molecular features, such as the nucleotide sequences of genes. Biologists often compare the sequences of related (or homologous) genes. If two species have the "same" gene, it is because they inherited it from a common ancestor. WebBiodiversity includes not only species we consider rare, threatened, or endangered but also every living thing—from humans to organisms we know little about, such as microbes, fungi, and invertebrates. At the Center for Biodiversity and Conservation, we include humans and human cultural diversity as a part of biodiversity.
