Solution:
Primitive animals are ones that have not changed dramatically over the millennia and remain very similar to their ancestors.
The first members of the human lineage lack many features that distinguish us from other primates. Although it has been a difficult quest, we are closer than ever to knowing the mother of us all. Until recently, the evolutionary events that surrounded the origin of the hominin lineage — which includes modern humans and our fossil relatives — were virtually unknown, and our phylogenetic relationship with living African apes was highly debated. Gorillas and chimpanzees were commonly regarded to be more closely related to each other due to their high degree of morphological and behavioral similarities, such as their shared mode of locomotion — knuckle-walking. But with the advent of molecular studies it has become clear that chimpanzees share a more recent common ancestor with humans, and are thus more closely related to us than they are to gorillas (e.g., Bailey 1993, Wildman et al. 2003). The similarities between the living African apes were thought to have been inherited from a common ancestor (=primitive features), implying that the earliest hominins and our last common ancestor shared with chimpanzees had features that were similar, morphologically and behaviorally, to the living African apes (Lovejoy 2009). With the discoveries of the earliest hominin species discussed below, it is now possible to critically examine these assumptions.
Answer:
The answer easier
Explanation:
It's the most commonly used form of classification or type of identification key used in biology as it simplifies identifying unknown organisms. Typically, a dichotomous key for identifying a particular type of object consists of a specific series of questions. When one question is answered, the key directs the user as to what question to ask next. Dichotomous keys typically stress identifying species by their scientific name, as each individual species has a unique scientific name.

Hello. You forgot to add the diagram.
The diagram is attached below.
Answer:
1. examination of homologous fossilized structures of primitive horses
Explanation:
As you can see in the diagram, to show the stages of the development of the modern horse, a comparison is made between the forelimb structure and the molar tooth of these horses (related to the adult form). These two factors of comparison establish the representation of fossilized homologous structures of primitive horses.
As you may already know, homologous structures are different body structures from different animals that have a strong similarity (because they are inherited from a common ancestor). When these animals die and these structures are conserved, we can say that they have been fossilized.
As the forelimb structure and the molar tooth of the horses shown in the diagram are homologous structures that were fossilized, we can say that option 1 is the correct answer to your question.
THE Answer Is B.I want to say because you going to need a high resolution but that's just what I want to say
