Which pair of organisms is the most closely related to primates?

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.

Are rabbits The most common ancestor of primates?

Although rabbits and hares have long been classified as close relatives of rodents (mice, rats, squirrels), a new study has concluded that the long-eared hoppers are really more closely related to primates, the mammalian order that includes monkeys, apes and humans. …

What would two organisms that are closely related have?

Two species are more related if they have a more recent common ancestor, and less related if they have a less recent common ancestor.

Which organism is most related to human?

Although figures vary from study to study, it’s currently generally accepted that chimpanzees (Pan troglodytes) and their close relatives the bonobos (Pan paniscus) are both humans’ closest-living relatives, with each species sharing around 98.7% of our DNA.

Are primates and rodents closely related?

Even so, just about all small mammals (e.g., rodents, shrews and moles) are more closely related to primates than large mammals.

Are primates closely related to rabbits?

RABBITS and hares are more closely related to primates than they are to rats and mice, according to Israeli and French researchers who have studied their proteins. Until recently, plants and animals were classified largely on the basis of their morphological similarities and differences.

Which of the following primates is the most closely related to humans quizlet?

Apes, such as chimpanzees, are the primates most closely related to humans.

How are humans and primates similar?

Living Primates

Humans are primates–a diverse group that includes some 200 species. … Because primates are related, they are genetically similar. Human DNA is, on average, 96% identical to the DNA of our most distant primate relatives, and nearly 99% identical to our closest relatives, chimpanzees and bonobos.

Which primate is least closely related to humans?

They labeled chimpanzees and gorillas as African apes and wrote in Biogeography that although they are a sister group of dental hominoids, “the African apes are not only less closely related to humans than are orangutans, but also less closely related to humans than are many” fossil apes.

Which group is most closely related to amphibians?

( The branching pattern of the phylogenetic tree makes it clear that amphibians are most closely related to reptiles and mammals.)

Which of the following primates groups is most closely related to lemurs?

Lemurs are thought to have evolved during the Eocene or earlier, sharing a closest common ancestor with lorises, pottos, and galagos (lorisoids).

Which anthropoids are most closely related to humans?

Which anthropoid species is most closely related to humans? Chimpanzees.

What is closely related to amphibians?

The most common amphibians are frogs and salamanders; common reptiles include turtles, crocodilians, lizards and snakes. … Reptiles are actually more closely related to birds and mammals than amphibians. The most obvious differences between amphibians and reptiles are the scales and claws of reptiles.

How closely related are reptiles and amphibians?

Once upon a time, reptiles and amphibians were classified together as one family. Scientists believe that reptiles evolved from their relative amphibians about 50 million years ago. Today it still can be difficult to identify all of the differences between reptiles and amphibians.

Which group of animals is most closely related to the arthropods?

The arthropods share many features with the phylum Annelida. Both arthropods and annelids are segmented, and members of the annelid class Polychaeta have a pair of appendages on each segment.

Are amphibians more closely related to mammals or fish?

Mammals are more closely related to birds than they are to amphibians. Both mammals and birds evolved from reptiles, a group of vertebrates that…

Are mammals more closely related to reptiles or amphibians?

We now think of this way of organizing reptiles and amphibians as inaccurate because more rigorous analyses of anatomy and genetics revealed that reptiles are more closely related to mammals than to amphibians.

What are the similarities between mammals and amphibians?

Similarities Between Mammals and Amphibians

Both mammals and amphibians consist of a notochord, dorsal central nervous system, pharyngeal gill slits, and a post-anal tail. Both mammals and amphibians are deuterostomes with bilateral symmetry. Both mammals and amphibians have two eyes with colored vision.
