Sea weeds come under polyphyletic group of the phylogeny.

What is phylogeny?

Phylogeny is the study of a species' or group's evolutionary history, particularly as it relates to relationships and lines of descent among large groups of animals.

The idea that distinct species of plants or animals descended from a single ancestor is fundamental to phylogeny and is widely recognized in the scientific community. Since the majority of animals that have ever existed are extinct and only a small portion of their fossilized remnants have been preserved in the fossil record, the evidence for these relationships is almost always insufficient. Therefore, the majority of phylogenies are based on inferential data and are hypotheses. Commonly, different phylogenies can be inferred from the same evidence.

Answer:

Mistery fossil genus A belongs to the monkeys of the old world.

Explanation:

Old-World Monkeys:

  • Most of them are big and robust
  • Some of them have hairless bulky structures in the posterior region of their bodies named ischiatic callosities. Their noses are pointing down and their holes are close to each other.
  • They have semi-thumb or no thumb at all. They have plane nails.
  • They have big brains and skulls.
  • They spend most of their time on the ground, resting on rocks or similar places too height. However, they can also be found in trees.

New-World Monkeys:

  • They are small-sized animals
  • Their brain and skulls are small.
  • Their nose holes are separated from each other and pointing at each side.
  • Their thumb is developed because they have arboreal habits, so they need the thumbs to hold to the branches and move.
  • They spend most of their time on trees. They hardly move on the floor.
  • They also have sharp nails.
  • They have long tails and no ischiatic callosities

<u>Mystery fossil genus A </u>

has been dated to the late Pliocene and early Pleistocene.

Its canines were sexually dimorphic, and it had bilophodont molars.

Its postcranial traits indicate that it was a terrestrial quadruped,

and its overall body size was over 55 lb (25 kg).

<u>Mystery fossil genus B </u>

has been dated to the early Miocene.

It is estimated that adults weighed around 2 lb (1 kg),

with some sexual dimorphism possible in body weight and canine size.

Mistery fossil genus A belongs to the monkeys of the old world.
