In Research
Two of the most commonly studied model organisms are invertebrates: the fruit fly Drosophila melanogaster and the nematode Caenorhabditis elegans. They have long been the most intensively studied model organisms, and were among the first life-forms to be genetically sequenced. This was facilitated by the severely reduced state of their genomes, but many genes, introns, and linkages have been lost. Analysis of the starlet sea anemone genome has emphasised the importance of sponges, placozoans, and choanoflagellates, also being sequenced, in explaining the arrival of 1500 ancestral genes unique to animals.
Arthropods, especially insects, are often used by forensic scientists. For example, some invertebrates are attracted to dead bodies.

Famous quotes containing the word research:
“Feeling that you have to be the perfect parent places a tremendous and completely unnecessary burden on you. If we’ve learned anything from the past half-century’s research on child development, it’s that children are remarkably resilient. You can make lots of mistakes and still wind up with great kids.”
—Lawrence Kutner (20th century)
“Our science has become terrible, our research dangerous, our findings deadly. We physicists have to make peace with reality. Reality is not as strong as we are. We will ruin reality.”
—Friedrich Dürrenmatt (1921–1990)
