What is homologous characteristics?
a homogulous series is a series of hydrocabrons which have the same type of bonds. i.e. are grouped by either single, double, or triple bonds, and thus follow a generic formula for how many Hydrogens to a number of carbons
Species that share a common ancestors have?
The limbs of Species A have a similar structure to the limbs of Species B, but perform a different function.
The sets of bones that support the limbs of vertebrates are called?
Ligaments ---- The sets of bones in vertebrates like us are: in the fore limb (arm), the humerus, radius and ulna. In the hind limb (leg) are the femur, tibia and fibula.
What structure is only found only in animals?
Only animals have limbs to move around. They also have nerve cells which is not present in plants. As they get their food from outside, they have a mechanism to digest food.
Which species would be considered more primitive based upon the structure of their limbs?
There are many organism with a forelimb with the most primitive trait. These animals include certain species of monkey animals.
Why does a dog have 4 legs and a bird has 2?
Both have four limbs. A bird's front limbs have been modified into special structures called wings. Similarly, a human's front limbs have been modified into arms. The basic quadrupedal structure is common to nearly all higher vertebrates (even some snakes have indications of vestigal limbs).
How are skeletons of amphibians similar to skeletons of other vertebrates?
they are similar when it comes to their limbs
What is the general name for the grouping nof vertebrates which have four limbs?
The name of a vertebrate with four limbs is a tetrapod (tetra meaning four and pod meaning foot).
Are sea turtles invertebrates or vertabrates?
They are vertebrates - they have a complete skeleton including spine, skull and limbs.

The limbs of Species A have a similar structure to the limbs of Species B, but perform a different function.
Do animals have limbs?
No, not every animal has a backbone. Only animals that belong to the phylum Chordata have backbones, while insects and mollusks do not.
What can you infer about the bones in the forelimbs of vertebrate species?
Example of vertebrates (having a spinal column) could be humans, whose fore limbs are arms, as we stand upright. Then there are animals like the horse, whose fore limbs (indeed all four limbs) are actually legs.
How many legs do turtles have?
depends, most have 4 but some like snakes actually have 2 stubs ( long gone legs) All vertebrates on Earth(life with spines, bones, etc) with limbs have four limbs with two exceptions: Sirens (a variety of salamander) and the Mexican Mole Lizard, which have only two front limbs and no hind limbs.

What are 2 limbs that are vestigal and why?
There are vestiges of leg bones and pelvises in cetaceans and snakes. The wings of ostriches and other flightless birds are also vestigial. These limbs are vestigial because although they are homologous to the legs and wings of other creatures, they have little or none of their function.
What an example of homologous structure?
If a bat, a human, an alligator, and a penguin all evolved from a common ancestor, then they should share common anatomical traits. In fact, they do. Compare the forelimbs of the human, the bat, the penguin, and the alligator. Find the humerus, radius, ulna, and carpals in each forelimb. Though the limbs look strikingly different on the outside and though they vary in function, they are very similar in skeletal structure. More significantly, they are derived from the same structures in the embryo. Structures that are embryologically similar, but have different functions, are called homologous structures. Though these animals look different, a comparison of homologous structures indicates that they are quite similar. This suggests that these animals evolved from a common ancestor.by: Lameace[=
