Answer:
20 million years
Explanation:
If we have a neutral mutation rate of one mutation per 5 million years, then the total of eight mutation between the two different species would be 20 million years. This is because both species will have 4 mutations in those 20 million years, so combined, both by 4, will have 8 mutations between them. So few mutations on so much time will result in two species that are very similar to each other even after 20 million years of evolution, even making them hardly distinguishable, especially if it comes to defining fossil records from them both. A nice example of this are the members of the felidae (cat) family, which are all very closely related, and are almost identical, thus making it extremely hard to distinguish two species of the same or similar size by their fossils.
Answer:
A. Class
Explanation:
Kingdom can be answered but the most specific is class
<span>If you are a chicken breeder who is interested in developing new hybrids that have many of the genes from the original ancestor birds, you should breed your birds with other birds that have similar genes to the original ancestor birds. In this way, you can combine the ancestor birds genes with those of your own birds to create a new hybrid.</span>
