How does comparing the embryos of different organisms support the theory of evolution?
The stages of development of the embryos of certain organisms are extremely similar, a fact that suggests the organisms had common ancestors.
The same kinds of cells that grow in similar patterns in different but related organisms produce?
The same kind of embryos
Do early chick and pig embryos have a similar structure and appearance?
The early embryos of all animals have a very similar appearance. This is no different for chicken and pig embryos.
How are different groups of vertebrates similar and different?
it is different by being different.
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 do embryos demonstrate evolution?
Basically, its the shape of the embryos of vertebrates. If the shape of the embryos are similar, that means they evolved from a common ancestor.More specifically, it's the pattern of nested hierarchies that is found when one compares the embryological developmentof species. Also, developmental atavisms, such as the branchial arches in human embryos, are important clues telling us about our ancestry.
Why are embryos from different animals so alike?
similar chromosomes make them up.
Why do embryos of different animals look similar?
Depending on what animal because animals are very different from one another, but that would mean you are considering humans not animals.
Why do all vertebrates very similar forms during development?
The Genes that control development in different vertebrates are only slightly different from each other
What term describes body parts of different organisms that are in similar form?
Which term describes body parts of different organisms that are similar in form?
The number and location of bones of many fossil vertebrates are similar to those in living vertebrates Most biologists would probably explain this fact on the basis of a the needs of the organisms?
No, b) a common ancestor.
Why are the fossils of vertebrates similar to the bones of living vertebrates?
probably cause current vertebrates have a backbone and ancient vertebrates ahd them to
