Dogs and Tigers are morally similar because they both have some of the same bone structure. Their are many different types of different breeds of each of these species. Dogs are an interesting type of species. We all know dogs are lovable creatures, man's best friend. They can be walked and they can be taught many things that rare creatures can understand coming from the human species.
Judging by both structures you notice they both have tails and 4 legs. Their similarities in bone structure is absolutely amazing. Tigers are much bigger than dogs. They eat bigger meals and bigger animals. Tigers are found in widely open areas such as forests, or jungles before they are rescued and placed in zoos and properly taking care. Most dogs are breed and/or bought and sold to the human species by other human species. We have more control over dogs. Rarely would any one of the human race capture a wild tiger and open them up to their homes. Tigers are a bit more dangerous than dogs. They require a little more security. Many people can find a stray dog, take it to the vet and get checked for rabies and shots and immediately have a new pet. I wouldn't recommend it because its extremely dangerous, but some people have done it. Tigers and Dogs both share a common ancestor know as a Felidae, which later turned into a rank of carnivora of mammals once dinosaurs were extinct.
I believe butterflies and bees have analogous traits that were forced to have similarities due to the environment. Both of these species share a few common traits but operate in two totally different ways. Butterflies start off as caterpillars and form to a congou until they hibernate all winter and break free in spring once they turn into beautiful butterflies. Butterflies have big beautiful wings and they fly around the flowers which nourishes them. Bees on the other hand is a specie that makes honey. Bees come with a tail which stings, but once they sting you they die. Both of these species plant nectar and are important plant pollinators, but they are very different otherwise. The two share a common ancestor but didn't evolve from it.
Homologous traits are those that share a common ancestry but have distinctly different structures due to different functions.
ReplyDeleteNo problem with ancestry, since both are mammals and arose from a common ancestor who ate other animals... i.e. it was a meat-eater, though evidence also suggests that it was an omnivore who also ate insects (not Felidae, which is only the cat line.) Regardless, the tooth structure was one that benefited meat eaters.

But the problem comes in when you address the second requirement for homologs, that of different structures related to different function. There are some dietary differences between dogs and cats, but both are primarily meat eaters and have similar structure because of that. So what are the structural differences that would make these homologous.
One other point is that while Tigers are wild animals and the product of natural selection, dogs are domesticated and the product of artificial selection. So differences in structure may be because of artificial influences, not natural environmental ones. This makes this comparison more complicated and a difficult example to justify.
"I believe butterflies and bees have analogous traits that were forced to have similarities due to the environment."
You offer a good description of each organism but you never identify which trait pairing is the analogous pair. Analogous traits will have origins independent of genetic ancestry but arise due to similar environmental pressures. Which trait shared by bees and butterflies satisfy this description? Also, since both are insects, many of their traits may well share a common genetic origin, such as wing structure, body segmentation, antennae and mouth structure. It usually easier to locate analogous traits in organisms that are more distantly related, such as the wings in butterflies and birds.
Make sure you review these concepts and understand the key differences between analogous and homologous traits. Email me if you need additional clarification.
hello quishia!
ReplyDeletei liked how you used the tiger and puppy pictures, very cute! and i also like how you pointed out that both animals do hunt with their teeth and make sure that their families and them selves are fed, although i don't think the tiger and dog share a common ancestor, over all great job!
