How do you create a Cladogram?

  1. Step 1: Pick Organisms for Your Cladogram.
  2. Step 2: Pick One Ancestral and One Derived Characteristic to Designate the Outgroup.
  3. Step 3: Pick Derived Characteristics for the Ingroup (Part 1)
  4. Step 4: Pick Derived Characteristics for the Ingroup (Part 2)
  5. Step 5: Pick Derived Characteristics for the Ingroup (Summary)

What is the ingroup in a Cladogram?

Ingroup in biology is a group of taxa that is considered in determining evolutionary relationships. The taxa in an ingroup are closely related. In fact, they are sister groups, and they share a common ancestor. Therefore, taxa in an ingroup are descendants that split from the same node in the cladogram.

What are derived characteristics?

Derived characteristics are traits shared by the members of a group of organisms with many similarities, known as a clade. This indicates that derived characteristics evolve as a result of the clade’s evolution. Shared derived characteristics are essential to phylogenetic ordering.

What is special about birds?

Birds were able to become flying machines largely through the evolutionary gifts of feathers, powerful wings, hollow bones, warm blood, a remarkable respiratory system, and a large, strong heart.

What are the economic importance of birds?

Economic Importance Domesticated birds, such as chickens and turkeys, are raised for meat and eggs. Chickens account for much of human poultry consumption, although turkeys, ducks, and geese are also relatively common. Many species of birds are also hunted for meat.
