bekas [8.4K]

DNA evidence and the fossil record indicate are the ancestors of the living cetaceans were land-dwelling mammals. DNA evidence allows to trace the evolutionary origin of taxonomic groups.

DNA evidence refers to the linear order of nucleotides, which can be used to trace the evolutionary origin of a particular taxonomic group.

When the linear order of DNA nucleotides is conserved, it is known as sequence homology.

Fossils are preserved remains of organisms that once lived on the Earth, which can also be used as evidence to trace the evolutionary origin of a given group.

How does the possible impact of a chromosomal mutation that occurs?
Papessa [141]
  If the mutation occurs during meiosis, the mutation will be incorporated into a gamete. If that gamete is the one that eventually fuses with another gamete (i.e. if it's the sperm that fertilizes the egg), that mutation will be passed on to the offspring. As all the offspring's cells are the result of the first two gametes, all the organism's cells will have that mutation. Obviously this can have dire consequences for the offspring, if the mutation is harmful.

Compare a bituminous roof membrane to a single ply roof membrane.
Digiron [165]

<span>Single-ply membranes are a assorted and promptly increasing group of sheet materials that are functional to the roof in a single layer. As equated to built-up membranes, they need less on-site labor, and they are usually more flexible and therefore less liable to to cracking and ripping. They are attached to the roof surface by any of several means.</span>
