Younger fossils are often morphologically different from older fossils in a lineage. How do paleontologists think the morphologi
photoshop1234 [79]

Answer:

Paleontologists thinks that the younger fossils are a species that underwent an-agenesis, gradually evolving a new morphology or/and the younger fossils are a new species that branched off the older one, rapidly evolving a new morphology.

Explanation:

Fossils are the safeguarded remains or hints of creatures, plants, and different life forms from an earlier time. Fossils range in age from 10,000 to 3.48 billion years of age. The perception that specific fossils were related with certain stone layers drove nineteenth century geologists to perceive a land timescale. Like surviving life forms, fossils differ in size from minuscule, similar to single-celled microscopic organisms, to monstrous, similar to dinosaurs and trees.

Fossils give strong proof that living beings from the past are not equivalent to those discovered today; fossils show a movement of advancement. Fossils, alongside the similar life systems of present-day life forms, comprise the morphological, or anatomical, record.

By contrasting the life structures of both present day and terminated species, paleontologists can deduce the ancestries of those species. This methodology is best for life forms that had hard body parts, for example, shells, bones or teeth. The subsequent fossil record recounts the account of the past and shows the development of structure more than a great many years.

Describe the structure and function of a root hair cell
Nadya [2.5K]
Root hair cells absorb minerals and water from the soil.


The water absorbed by the root hair cells passes through the plant in xylem tubes, to then reach the leaves. The energy from the sun is then used to convert water(H2O) into hydrogen (H) and oxygen(O2).

I hope this helps
