The Genes that control development in different vertebrates are only slightly different from each other
What else can I help you with?
Why is the amniotic egg considred an important evolutionary breakthrough?
It shows how life forms are all very similar in early development stages.
How are dolphin embryos and human embryo similar?
Dolphin embryos and human embryos share several similarities due to their common mammalian ancestry. Both undergo similar stages of development, including the formation of major organs and body structures during gestation. Additionally, they exhibit similar genetic and cellular processes, such as the development of a neural tube and the presence of limb buds. These similarities highlight the shared evolutionary traits among mammals, despite the significant differences in their adult forms and habitats.
Among coelomates in which of these does development occur by radial cleavage and the anus forms before the mouth?
Animals with deuterostome development exhibit radial cleavage, where the cells divide parallel or perpendicular to the polar axis of the embryo. In deuterostomes, such as echinoderms and chordates, the anus forms before the mouth during embryonic development.
Are warewolves vertebrates?
Yes, werewolves are typically portrayed as creatures with a humanoid form that can transform into a wolf-like creature. As such, they are considered vertebrates because they possess a backbone and spinal column in both forms.
What vertebrate group is a lizard in?
All vertebrates are members of the phylum Chordata, but not all creatures in Chordata are vertebrates. There are three subphylums in Chordata. Two of them are invertebrates - Urochordata (tunicates) and Cephalachordata (lancelets), while the third is Vertebrata (vertebrates). This phylum includes all animals which have a hollow nerve cord and a notochord at some stage during their development. In the case of vertebrates, the notochord is present in the embryo, and develops into the vertebral body. In the tunicates, the adult form no longer has the notochord. Another characteristic they share is that, at some stage during their lives, they have pharyngeal grooves and pouches that develop into other essential parts of their anatomy (many textbooks still state that all vertebrate embryos have gill slits, but there has been a great deal of development in the science of embryology to refute this claim). Chordates all have a post-anal tail, which means an extension of the notochord and nerve chord behind the anus, although this feature is no longer present in the mature forms of some creatures such as frogs, and some mammals such as people. Chordates also have a closed circulatory system, although not all Chordates have an actual heart like the vertebrate Chordates do.
Why do all vertebrates very similar forms during development?

Why do vertebrate have very similar forms during developement?

What happens during the neurula stage?
The neurula stage is the stage of development of the nervous system of vertebrates. In a human fetus, if there are some failure in the development of the nervous system during the neurula stage, some serious birth defects could occur.
The variation in the forms of adult vertebrates probably arose through mutations in genes?
the variation in the forms of adult vertebrates probably arose through mutations in dominant genes
The most successful forms of life that have ever evolved are the?
vertebrates
What tissue forms the disks between vertebrates?
Fibrous cartilage
Some vertebrates can go through nymph and pupa forms?
No
Why is a notochord important to vertebrates?
Notochords are important to vertebrates because it forms the main support of the body. A notochord is a flexible rod-like structure.
What is the significance of the embryonic tail in human development?
The embryonic tail in human development is significant because it represents a stage in evolution where humans shared a common ancestor with other vertebrates. It eventually regresses and forms the coccyx, or tailbone, which is important for providing support and anchoring muscles.
Why is the amniotic egg considred an important evolutionary breakthrough?
It shows how life forms are all very similar in early development stages.
Do vertebrates posses forms and postures?
Yes as they have backbones and skeletons (Like humans and animals)
What tissue forms the?
During embryonic development, the stomach (like the bulk of the rest of the gastrointestinal system) forms from endoderm, the innermost layer of the three major germ layers.
