Answer:
Rocks deteriorating the ocean floor
Explanation:
As rocks scrape past the ocean floor they chip away at it smoothing it (erosion) out but due to continental drift and magma rising and cooling it causes the new igneous rock forms on the ocean floor making it rough and rugged.
When thinking about this think about a pebble on the beach, what it is?
rounded due to erosion just as scientists thought the ocean floor would be.
Mitochondrial DNA (mtdna) recovered from a fossil hominin from sima de los huesos in northern spain shows connections to the mtdna of the Denisovans.
The Sima de los Huesos showed distinctive proof of DNA survival over an extended period of time. Based on the enzymatic amplification of a few short mitochondrial DNA (mtDNA) fragments from Middle Pleistocene cave bear bones. Given that the Sima de los Huesos fossils have Neanderthal-derived characteristics (such as in their dental, mandibular, midfacial, supraorbital, and occipital morphology), it is unexpected that the mtDNA from these fossils has a common origin with Denisovan rather than Neanderthal mtDNAs.

For the answer to the question above, I think this is <span>False and the answer is based on the book, Nirenberg, and Matthaei. 19- unlabeled amino acids. Cys-Val-Cys-Val. (pg. 318 & 319)</span>. I hope I helped you somehow. Have a nice day!
Skin color<span> is due primarily to the presence of a pigment called melanin , which is controlled by at least 6 genes. Both light and dark complexioned people have melanin. However, two forms are produced--pheomelanin , which is red to yellow in</span>color<span>, and eumelanin , which is dark brown to black</span>
