Which type of embryos have pharyngeal slits?
all chordates - novanet now all you guys get back to work :D
What types of embryos have pharyngeal slits?
all chordates
Did bird embryos have gill slits?
I am not sure if this is a correct answer to your question, because i am no expert on fowl, but I am not aware of birds ever having gill slits in there formation. Humans have slits that have been misconstrued to be gill slits but those are there to help with the formation of your neck and ears. I imagine that the two cases are related, but, like I said, I am no expert on birds.
Why does comparative embryology show similarities between organisms that do not appear to be similar as adults?
Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. All of the animals except for fish, lose their gills slits by adulthood. Some of them also lose their tail. In humans, the tail is reduced to the tail bone. Thus, similarities organisms share as embryos may be gone by adulthood. This is why it is valuable to compare organisms in the embryonic stage
How embryology is used to study evolution?
Embryology is used in evolution because its shows a common ansetor. For example, a human and fi sh have similar embryos. Both embryos have pharyngeal slits. In a fish those develop into gills. In humans those turn into our ears.
All vertebrate embryos develop gills during one of the many growth phases in their development?
It would be more appropriate to say that all vertebrate embryos develop pharyngeal gill slits during one of the many phases in their embryonic development. This is because while gills are specifically present in fishes, pharyngeal gill slits are a general chordate feature.
Which type of system compose of the skeleton of sharks and human embryos?
Cartilage.
When was The Slits created?
The Slits was created in 1976.
When did The Slits end?
The Slits ended in 1982.
Why do fetuses develop pharyngeal slits?
The development of pharyngeal slits in fetuses is believed to be a call back to our evolutionary history. As I'm sure your aware humans and any living vertebrates belong to the phylum Chordate which is part of the Deuterostomes branch of the animal kingdom. You may have heard about the theory of how modern day mammals and so hence man evolved from fish. Well the presence of pharyngeal slits in fetuses is one piece of evidence for this theory. As pharyngeal slits are used in simple organism such as Hemichordates to filter feed in water. Organisms classified as Deuterostomes are done so by the presence of these pharyngeal slits at some stage during their development ( In fish embryos it is the pharyngeal slits which develop into the gills), amongst some other similar developmental patterns. I hope this helps to answer your question.
