Answer:

The correct answer for: do perch and chimps share a common ancestor? Is yes and its name is: choanoflagellates

Explanation:

To understand the answer we need to analyze its context. First of all, this is only theory and yes, it is believe that choanoflagellates are the closest unicellular ancestors to animals. If this is correct yes all animals on earth share the same ancestor and are those guys. However, if we turn into the primate mammal family species and the pikaia fmily species share direct ancestors the answer is no. But as animals, we do share an ancient ancestor. So yes, they share one ancestor. Even though it's a pretty old one.

<span>The correct answer is YES.
Perch and chimps they share a common ancestor.

A common ancestor is species that multiple species do share a species. Many years ago, ancestors began to diverge. This diverging led to different lineages and later raised to different species.
For example, human and apes evolved from a common ancestor. Humans and yeast they share the same common ancestor in that human have genes that codes for myosin, and also a gene in yeast which too codes for myosin protein.</span>

Complete Question

Which of the following situations would pose a major difficulty for applying the biological species concept?

a) Two populations of sexually reproducing plants that can be bred easily in the same location under field conditions

b) Two populations of sexually reproducing insects that can be bred easily in the same location under field conditions

c) Five snail fossils taken from the same locality during a 400,000-year time span

d) Dimorphic mating pairs of birds

e) Monomorphic mating pairs of birds

Solution -

According to the biological species concept, two or more organisms that look alike does not mean that they belong to the same species. In order to consider that two organisms belong to the same species, it is essential for them to be able to interbreed or mate.

For example –

Western meadowlarks and Eastern meadowlarks look identical to one another but they do not interbreed with each other and hence they belong to different species.

Hence, option C is correct
