Scorpion and Daddy long-legs. The Daddy long-legs isn't actually a spider.
Inbreeding!
No they are two different species of animals.
Bats are closely related to other mammals, such as primates, rodents, and carnivores. They belong to the order Chiroptera, which is divided into two suborders: the Megachiroptera (large fruit bats) and the Microchiroptera (small insect-eating bats).
Canis familiaris (domestic dog) is most closely related to Canis lupus (wolf).
Not closely. Lyrebirds are Passerines, and peacocks are Galliformes. While the two both have long, decorative tails, they are not related beyond the class Aves.

Petrels, loons, storks, grebes, flamingos, ducks, albatrosses, pelicans and herons.
If you mean are most closely related to dinosaurs sharks and crocodiles closest alive today.
the frog and the spider
Humans and chimpanzees are the two species that are most closely related to each other.
the blue whale and the the domestic
The cat and tiger are most closely related, and are both of the family Felidae. Even though the numbat and eastern barred bandicoot are both marsupials, that is where the similarities end.
Humans and chimpanzees are the two species that are most closely related in terms of genetic similarity.
No, they are not. As you move down the species classification system, the last category the two animals share in common is that they are both carnivores. Meerkats are in fact more closely related to mongooses.
Humans and chimpanzees are the two animals most closely related in terms of amino acids, sharing about 98-99% of their DNA. This genetic similarity translates to a high degree of similarity in protein sequences, as amino acids are the building blocks of proteins. Other closely related species, such as gorillas and orangutans, also show significant similarities, but humans and chimpanzees stand out as the closest.
