Which animal groups are most closely related to each other?
The organisms within a phylum are considered to be more closely related to each other than they are to organisms of other phyla.
Which pair of organisms is most closely related?
Of the given pairs, the organisms most closely related taxonomically are the b) Spider and crayfish. Both of these organisms are arthropods and share…
Which species is most closely related to species B?
Species A and B are linked through a recent common ancestor that is not shared by any other taxa on the tree and are therefore known as “sister taxa.” The next closest relative of species A and B is species C, with whom they share an ancestor to the exclusion of species D, E, and F.
What is most closely related to animals?
Chimpanzees now have to share the distinction of being our closest living relative in the animal kingdom. An international team of researchers has sequenced the genome of the bonobo for the first time, confirming that it shares the same percentage of its DNA with us as chimps do.
What is a group of closely related species?
genus – a group of closely related species.
Which two modern organisms are most closely related?
Your first question asks “Which two modern organisms are likely to be most closely related?” The two most closely related organisms are 3 and 4. They share a single node. All of the other species exist by themselves at separate nodes.
What would two organisms that are closely related have?
Generally, the longer ago the last common ancestor lived, the less the organisms have in common. Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms.
Which organism is B more closely related to A or C?
The descendants may be living or extinct. The descendants may be individual species but they do not have to be. A is more closely related to B than it is to C because it shares a more recent common ancestor with B when compared to C.
Which taxa are most closely related?
A sister group is a pair of taxa that are most closely related to each other. Humans are most closely related to chimpanzees, so humans & chimpanzees form a sister group.
Which animal is least closely related to the human?
Aardvarks, aye-ayes, and humans are among the species with no close living relatives.
What are related species?
species, in biology, classification comprising related organisms that share common characteristics and are capable of interbreeding. This biological species concept is widely used in biology and related fields of study.
Which level of classification contains the most closely related species?

What primates are most closely related to humans?
Among the living primates, humans are most closely related to the apes, which include the lesser apes (gibbons) and the great apes (chimpanzees, gorillas and orangutans).
What animals are closely related to humans?
Humans, chimpanzees, gorillas, orangutans and their extinct ancestors form a family of organisms known as the Hominidae . Researchers generally agree that among the living animals in this group, humans are most closely related to chimpanzees, judging from comparisons of anatomy and genetics.
What animal is the closest to humans?
The chimpanzee is the closest animal relative to humans. A new study of genes in humans and chimpanzees pins down with greater accuracy when the two species split from one.
What is the closest species to humans in animal kingdom?
Researchers determined back in 2005 that chimpanzees share somewhere between 98.6 and 99 percent of our DNA. They’re closer to humans than they are to gorillas! Remarkably, female chimps also share a reproductive cycle similar to that of humans, with most reaching sexual maturity just before or during their teenage years.
