The set of species derived from one common ancestor.
To build phylogenetic trees, a variety of data can be employed, including genetic information, mitochondrial DNA sequences, ribosomal RNA genes, and any relevant genes, as well as morphological information such as structural characteristics, organ kinds, and specific skeletal arrangements
<h3>What is a Phylogenetic tree ?</h3>
A phylogenetic tree, also called a phylogeny, is a diagram that shows the evolutionary branches from which various species, creatures, or genes have descended from one another.
- A phylogenetic tree can be used to track a species' evolutionary history back via the tree's branches and find their common ancestors along the way.
- A lineage may preserve some of its ancestors' characteristics over time, but it will also change over time to accommodate the environment.

Answer:
Muscle tissue would break down to supply amino acids.
The flu vaccine changes every year. The flu vaccine is based on a predicted strain that is anticipated to be the most infectious that year. Thats why people who sometimes get the vaccination still get the flu, they don't have the antibodies for the strain they were infected with. Strains for viral disease don't change very much and usually the vaccination for them cover them well.
The answer would be algae or phytoplankton
