What conclusion can be drawn from embryological development? Insect and bird wings are similar in function but not in structure. Paleontologists have used fossils to trace the evolution of the modern camel. Many organisms have structures with no apparent function found during embryo development. The presence of gill slits and tails in early vertebrate embryos shows that they may share a common ancestor.

Using vertebrates as an example, how does comparative embryology prove evolution?
On a deep sea expedition, you capture a previously undiscovered sea creature that appears to represent a new phyla. It happens to have fertilized eggs that you get to spawn. You watch its development to determine which group of animals it might belong to. You see that the mouth develops first, and it goes through several larval stages in which it molts and regrows its skeleton. What other traits is it likely to have based on this type of development Radial symmetry Coelem Central Nervous System Two germ layers present yes or no for each
In vertebrate evolution, which of the following evolved most recently? Amniotic egg Jaw Feathers Limbs
Insects have three thoracic (trunk) segments. While researchershave found insect fossils with pairs of wings on all threesegments, modern insects have wings or related structureson only the second and third segment. It turns out thatin modern insects, Hox gene products act to inhibit wingformation on the first segment. The treehopper insect (above)is somewhat of an exception. In addition to having wingson its second segment, the treehopper’s first segment has anornate helmet that resembles a set of thorns, which a recentstudy has found to be a modified, fused pair of “wings.” Thethorn-like structure helps to camouflage the treehopper intree branches, thus reducing its risk of predation. Explain howchanges in gene regulation could have led to the evolution ofsuch a structure.
Which of the following is not a statement of von Baer's laws? Less general characters develop from the more general, until finally the most specialized appear. The general features of a large group of animals appear earlier in development than do the specialized features of a smaller group. (C) All of the above are Statements of von Baer's laws. The early embryo of a higher animal is never like a lower animal, but only like its early embryo. The embryo of a given species, instead of passing through the adult stages of lower animals, departs more and more from them.

Mammals belong to a group of amniotes known as synapsids. Three major lineages of mammals had emerged by the early Cretaceous period. In a tabulated form, compare these three lineages to illustrate their diversity in terms of: a. Embryonic developmen, b. How the young are fed and c. Period of gestation
Can someone pleae help with 3 question for my biology homework thank you 1)List two traits that animals share with other organisms, and three traits that are unique to animals. 2)Explain the difference between protostome development and deuterostome development. Use full sentences. 3)As discussed in class, animals are classified into different phyla based on the presence of tissues. Define the two options for animals with true tissues, and give a specific animal phylum as an example of each option.
