Human and apes have 5 fingers that are used for grasping objects, so they have the same function, but they also have a common ancestor and are closely related, that means that this is an example of homologous structures. In evolutionary biology, the term homologous structures means that there are organs and skeletal elements of animals and organisms, that by virtue of their similarity, suggest their connection to a common ancestor.
It is problematic due to antibiotic-resistance that would
occur. This extensive use and abuse of antibiotics result in the emergence of resistant
strains of bacteria. Some types of
bacteria that cause serious infections in humans have already developed
resistance to most or all of the available treatments, and there are very few
promising options in the market.

Explanation:
Livestock producers and breeders rank livestock on their ability to produce high quality, efficient breeding animals and market-worthy <u>offspring</u>.
To be able to effectively evaluate breeding and market animals is of vital economic importance for the animal markets. The same traits used to evaluate <u>high-grade slaughter animals</u> are also important in the <u>grading </u>of <u>breeding stock</u>.
When we judge livestock we classify them as:
- Superior livestock
- Average livestock
- Inferior livestock
We are looking for the most desirable traits to fit our particular market and genetic needs. The "Livestock Judging Manual" indicates that some of the most prevalent traits necessary to score a better rating are:
- <em>Live weight</em>
- <em>Fat depth</em>
- Muscling
and many more. The most important of which is muscling given that an animal with more muscle will produce more desirable meat for the average consumer, and therefore can be sold at higher prices.
