Question: What are the closest living relatives of the family of lizards that includes the species Varanus komodoensis?

full_context: Document 1: Dracaena aletriformis: Dracaena aletriformis is commonly known as the Large-leaved Dragon Tree. These plants are found in forest in the eastern areas of South Africa from Port Elizabeth to northern and eastern Gauteng. They are also found in Swaziland, but are most common in the coastal and dune forests of KwaZulu-Natal.
Document 2: Dracaena kaweesakii: Dracaena kaweesakii (Kaweesak's dragon tree; Thai: Chan nuu or Chan pha krai) is a species of dragon tree. It can reach 12 m in both height and crown diameter. It is only found growing atop the limestone mountains in the Loei and the Lop Buri Provinces of Thailand.
Document 3: Heloderma: Heloderma, the only genus of the family Helodermatidae, consists of venomous lizards native to the southwestern United States, Mexico, and as far south as Guatemala. It includes five separate species, with two subspecies. Their closest living relatives are the anguid lizards.
Document 4: Emu: The emu ("Dromaius novaehollandiae") is the second-largest living bird by height, after its ratite relative, the ostrich. It is endemic to Australia where it is the largest native bird and the only extant member of the genus "Dromaius". The emu's range covers most of mainland Australia, but the Tasmanian emu and King Island emu subspecies became extinct after the European settlement of Australia in 1788. The bird is sufficiently common for it to be rated as a least-concern species by the International Union for Conservation of Nature.
Document 5: Discovery reptiles: Discovery Reptiles is a traveling zoo in Naples, Florida. Its collection includes some of the most endangered reptiles on earth. Discovery Reptiles was founded in 2009, and started with just four animals. They had two Red Tailed Boa Constrictors "Boa constrictor", an Asian Water Monitor"Varanus salvator" and an African Rock Monitor"Varanus albigularis ionidesi". Over the course of 2010 Discovery Reptiles slowly added to their animal collection with the addition of a Caiman Lizard "Dracaene guianensis" and Rhinoceros Iguana "Cyclura cornuta" which is listed as Threatened by the International Union for the Conservation of Nature (IUCN. The main purpose of the zoo is to educate the public on conservation and the importance of biodiversity; in order to do that it wanted to add an animal that would capture the attention of audiences around Southwest Florida. Discovery wanted an animal not found in the Southwest Florida region or commonly found in zoos, so they added a young female Yellow Anaconda "Eunectes notaeus".
Document 6: Peter Ouwens: Pieter Antonie Ouwens (14 February 1849, Amsterdam – 5 March 1922, Buitenzorg) was a Dutch scientist and Director of the Java Zoological Museum and Botanical Gardens. He is best known for writing the first formal description of the Komodo dragon ("Varanus komodoensis") in 1912.
Document 7: Paramacellodidae: Paramacellodidae is an extinct family of scincomorph lizards that first appeared in the Middle Jurassic around 170 million years ago (Ma) and became extinct in the Early Cretaceous about 100 Ma. It was one of the earliest groups of lizards to have undergone an evolutionary radiation, with members found across the supercontinent Laurasia. The phylogenetic relationships and constituent species of Paramacellodidae are uncertain. Many studies regard it to be closely related to Scincoidea, a large group that includes skinks and their closest extinct relatives, and possibly also to Cordyoidea, a group that includes spinytail lizards and relatives. Like modern skinks, paramacelloidids had rectangular bony plates called osteoderms covering most of their bodies, including their backs, undersides, and tails. They also had short and robust limbs.
Document 8: Pseudechis: The genus Pseudechis contains the group of elapids commonly referred to as the black snakes. These snakes are found in every Australian state with the exception of Tasmania and some species are found in Papua New Guinea. They inhabit a variety of habitat types, from arid areas to swampland. All species are dangerous ("Pseudechis" signifying "like a viper", Greek "echis") and can inflict a potentially lethal bite. Most snakes in this genus reach about 2 metres and vary in colour. Some species are brown, where others are black. The most recognisable and widespread species in the genus are the red-bellied black snake ("Pseudechis porphyriacus") and the Mulga snake (king brown) ("Pseudechis australis"). These snakes feed on lizards, frogs, birds, small mammals and even other snakes. All species lay eggs, except the red-bellied black snake. The genus "Pailsus" is a synonym of "Pseudechis", and more work is needed to understand species limits among the smaller species of the group.
Document 9: Diapsid: Diapsids ("two arches") are a group of amniote tetrapods that developed two holes (temporal fenestra) in each side of their skulls about 300 million years ago during the late Carboniferous period. The diapsids are extremely diverse, and include all crocodiles, lizards, snakes, tuatara, turtles, and dinosaurs (both avian and non-avian). Although some diapsids have lost either one hole (lizards), or both holes (snakes and turtles), or have a heavily restructured skull (modern birds), they are still classified as diapsids based on their ancestry. At least 7,925 species of diapsid reptiles exist in environments around the world today (nearly 18,000 when birds are included).
Document 10: Aldabra giant tortoise: The Aldabra giant tortoise ("Aldabrachelys gigantea"), from the islands of the Aldabra Atoll in the Seychelles, is one of the largest tortoises in the world. Historically, giant tortoises were on many of the western Indian Ocean islands, as well as Madagascar, and the fossil record indicates giant tortoises once occurred on every continent and many islands with the exception of Australia and Antarctica. Many of the Indian Ocean species were thought to be driven to extinction by over-exploitation by European sailors, and they were all seemingly extinct by 1840 with the exception of the Aldabran giant tortoise on the island atoll of Aldabra. Although some remnant individuals of "A. g. hololissa" and "A. g. arnoldi" may remain in captivity, in recent times, these have all been reduced as subspecies of "A. g. gigantea".
Document 11: Komodo Biosphere Reserve: The Komodo Biosphere Reserve and National Park is situated between Flores and Sumbawa in Indonesia. It is renowned for its population of about 5,000 giant lizards, called 'Komodo dragons' ("Varanus komodoensis"). They exist nowhere else in the world and are of significant interest to scientists studying the theory of evolution.
Document 12: Komodo dragon: The Komodo dragon ("Varanus komodoensis"), also known as the Komodo monitor, is a large species of lizard found in the Indonesian islands of Komodo, Rinca, Flores, Gili Motang, and Padar. A member of the monitor lizard family Varanidae, it is the largest living species of lizard, growing to a maximum length of 3 m in rare cases and weighing up to approximately 70 kg .
Document 13: Varanidae: The Varanidae (varans) are a family of lizards of the superfamily Varanoidea. The family, a group of carnivorous and frugivorous lizards, includes the extinct Megalania (the largest known lizard), the Komodo dragon (the largest living lizard), and the crocodile monitor. The Varanidae contain the living genus "Varanus" and a number of extinct taxa. Their closest living relatives are the anguid and helodermatid lizards.
Document 14: La Gomera giant lizard: The La Gomera giant lizard ("Gallotia bravoana"; Spanish: Lagarto Gigante de la Gomera ) is a lacertid (wall lizard) species that can be found on the island of La Gomera, one of the Canary Islands.
Document 15: Iguana: Iguana ( , ] ) is a genus of herbivorous lizards that are native to tropical areas of Mexico, Central America, South America, and the Caribbean. The genus was first described in 1768 by Austrian naturalist Josephus Nicolaus Laurenti in his book "Specimen Medicum, Exhibens Synopsin Reptilium Emendatam cum Experimentis circa Venena". Two species are included in the genus "Iguana": the green iguana, which is widespread throughout its range and a popular pet, and the Lesser Antillean iguana, which is native to the Lesser Antilles and endangered due to habitat destruction.
ground_truth: the anguid and helodermatid lizards.
