A homeobox is a DNA sequence, around 180 base pairs long, found within genes that are involved in the regulation of patterns of anatomical development in animals, fungi, plants, and numerous single cell eukaryotes. Homeobox genes encode homeodomain protein products that are transcription factors sharing a characteristic protein fold structure that binds DNA to regulate expression of target genes.

In sub-phylum Vertebrata, the notochord present in embryos gets replaced by a cartilaginous or bony vertebral column in adults. But in cephelochordates, notochord persists throughout life as such and in urochordates, notochord is present only in larval stages and absent in adults.

Vertebrates are more complex organisms when compared to invertebrates. The primary difference between the two is that vertebrates possess a backbone and an internal skeleton. In some vertebrates, the bones are replaced with cartilage, as seen in sharks. Another defining characteristic of vertebrates is that they reproduce sexually.

Vertebrates Meaning “Vertebrates are animals that possess a vertebral column and/or notochord at any point in their lives.” One of the ways life is classified is through the presence or absence of the vertebrate. Vertebrates and invertebrates evolved from a common ancestor that was speculated to have lived around 600 million years ago.

In birds and lower vertebrates, there is a pervasive role for DM domain of genes in gonadal sex differentiation, and it is considered that these genes have an ancient association with sex.

Determining the drivers of extinction risk has been a key pursuit of conservation biology.

Results show that the smallest- and largest-bodied vertebrates have elevated extinction risk.

A craniate is a member of the Craniata, a proposed clade of chordate animals with a skull of hard bone or cartilage. Living representatives are the Myxini, Hyperoartia, and the much more numerous Gnathostomata. Formerly distinct from vertebrates by excluding hagfish, molecular and anatomical research in the 21st century has led to the reinclusion of hagfish, making living craniates synonymous with living vertebrates. The clade was conceived largely on the basis of the Hyperoartia ...

All of these vertebrae and ribs are connected to strong muscles. Together, the bones and muscles protect the snake’s internal organs. A snake’s internal organs include a long throat with an even longer stomach. The snake also has two lungs, a liver, kidneys, and intestines stretched out in its long body.

Sharks do have two reproductive organs which are known as claspers which act as penises. The claspers are the main differentiating organ between a male and a female shark. This fact may be a known fact to biologists especially people studying marine biology but is off course a new information to many people. Now recently a study has been done on ...

Although most fish species have probably been discovered and described, about 250 new ones are still discovered every year.
