What visual aid is like a family tree and shows the phylogenetic of organisms?
The family tree like visual aid for organisms is called a cladogram. It shows the phylogenetic relationships and represents the evolutionary tree of life.

What does a phylogenetic tree have in common with a cladogram?
It shows relationships between organisms. It shows lineage back to the first common ancestor.
What is Diagram that shows evolutionary relationships?
Phylogenetic tree
The phylogenetic tree below shows similarities in the amino acid sequences of cytochrome-C of several organisms Which organism is most distantly related to the rhesus monkey?
The Human
What visual aids is a like family tree and shoes the phylogenic relationships of organisms?

How are fossils dated and how does this relate to phylogenetic trees?
There are many different methods of dating fossils including their geological stratum and carbon dating. Phylogenetic trees are dated by their geological stratum because they have something called the COI gene that shows they have roots from a long time ago.

An ecosystem that has many different kinds of organisms shows?
An ecosystem that has many different kinds of organisms shows efficient biodiversity. Terrestrial biodiversity tends to be highest at the equator.
How do phylogenetic trees show envolutionary relationships among organisms?
Phylogenetics is the study of the evolutionary history of organisms. Organisms have evolved from shared common ancestors through speciation and natural selection. The phylogentic tree shows us the degree of relatedness of organisms. The more recently a species diverged the more closely related they are as they still share genetic material and the organisms will look more similar eg. (humans and chimpanzees share 94% of genetic material). If the species diverged longer ago, the branches are further apart and they are more distantly related as share less similar genetic material as organisms have evolved over time. Also molecular phylogenetics compares DNA and protein molecules to see how closely related the species are if these molecules are similar. They are compared by looking at the sequence of bases or hybridisation where two single strands of DNA are mixed forming hydrogen bonds between specific base pairs. The more hydrogen bonds that form means that the DNA is more similar.
