Question

To which of these subgroups would humans belong to in the phylum chordata?

1) Mammals
2) Reptiles
3) Birds
4) Fish

Answer 1

Humans belong to the subgroup Mammals within the phylum Chordata. Despite lacking some traits like the notochord as adults, they exhibit these during embryonic development, placing them firmly within Chordata.

Step-by-step explanation:

To which of these subgroups would humans belong to in the phylum chordata? The answer is: 1) Mammals. In the classification of chordates, humans are included in the Mammalia class, which is part of the subphylum Vertebrata.

This subphylum represents all chordates that have a backbone. Humans share characteristics with other mammals, such as having hair, producing milk to feed their young, and possessing a differentiated dentition. '

Mammals are a diverse group that includes primates, of which humans are a part, characterized by their developed hands and feet, large brains, and shortened snouts.

As chordates, all mammals have a notochord at some stage of their life cycle, though in humans and other vertebrates, it is reduced during development and surrounded by the backbone.

Thus, despite adult humans lacking some defining traits of chordates like the notochord, they are still classified in the phylum Chordata because they exhibit these traits during their embryonic development.

Answer 2

Humans belong to the subgroup Mammals in the phylum Chordata and are classified under the class Mammalia, distinguished by characteristics such as milk production. The correct answer is 1

Step-by-step explanation:

To which of these subgroups would humans belong to in the phylum chordata? Humans belong to the subgroup Mammals in the phylum chordata. Chordates are a diverse group of animals that share common features such as a notochord, which is a hollow nerve cord along the back.

Within the subphylum Vertebrata, which is a major group with

in the chordates, humans and other mammals are categorized because they all possess a backbone. This backbone is in fact, a development of the notochord found in all chordates.

When examining the classification of chordates, humans, as well as other primates, bats, and insectivores, are classified under the class Mammalia. This class is part of the larger group known as vertebrates, which includes fish, amphibians, reptiles, and birds, but is distinguished by traits such as the production of milk for offspring, which defines mammals. The correct answer is 1
