erm i dont know
no
There are meany ways for this to happen, even though most of these ways will take a long time to occur. Overall, yes, humanity will go extincnt at some point.
The evolutionary history of a species is often displayed in a phylogenetic tree. This will clearly show the history of the species, which is also known as phylogeny.
what are the species to be included in the reconstruction of the evolutionary history of Polytoma and why?
Phylogeny.
Americana is the folklore and artifacts and history of the United States. I do not believe it has anything to do with a species.
Phylogenetic Tree
History and science are the foundation of who we are as people and the reason we as a species are who we are.
they are remnants of structures found in the ancestral species
The evolutionary history of a species of a group of species is the way these species relate to each other. The evolutionary history of man, for example, shows that we have a more recent common ancestor with the genus Pan (chimpansees) than the genus Gorilla (gorillas).
A gene tree shows the evolutionary history of a specific gene, while a species tree shows the evolutionary history of a group of organisms. Gene trees focus on the inheritance of individual genes, while species trees show the relationships between different species.
One very important way that information is compared in the evolutionary history of a species is to use DNA. By checking how much is the same between species, we can see if those species are closely related or not. Our own DNA and that of the great apes are only different in about 1-2%.
