The study of evolutionary relationships that includes a branching pattern showing lineages diverging is called phylogenetic tree

Explanation:

The phylogenetic tree is composed of,

•Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches.

•Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor.

•Root → This is the older common ancestor that all lineages share. The first one in the tree.

Two or more lineages are more related to each other if they share a recent common ancestor. This means that they all diverge from the same node.

Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.

There are also different phylogenetic relationships between lineages.

•Apomorphies → Occur when the involved lineages share a trait that they inherited from their most recent common ancestor. This trait evolved for the first time in this ancestor. → This relationship is a homology.

•Plesiomorphies → occur when the involved lineages share a trait inherited from a common ancestor, but that is older concerning the present traits exhibited by other descendants of the same common ancestor. → This relationship is a homology.

•Homoplasy → Lineages share a trait that evolved independently in each group. → This relationship is an analogy.

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student, including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as edutech.
