Why is the tree of life a useful analogy to understand the history of life on Earth? Figure 11.18 illustrates one possible way an allopolyploidy can form. Island archipelagos like the Hawaiian Islands provide an ideal context for adaptive radiation events because water surrounds each island, which leads to geographical isolation for many organisms (Figure 11.16).

Speciation can result from natural selection acting on multiple heritable traits over time. The other form of polyploidy occurs when individuals of two different species reproduce to form a viable offspring called an allopolyploid. the evolutionary development of a biological species, as by geographical isolation of a group of individuals from the main stock, The formation of new biological species by the development or branching of one species into two or more genetically distinct ones. Scientists have discovered more than 1/2 of all plant species studied relate back to a species evolved through polyploidy. Nine of the resources in this package are free for content preview.

Encourage students to use Deep Tree as a research tool throughout your evolution unit. It is hypothesized that either through mutation or a behavioral mistake, flies jumped hosts and met and mated in apple trees, subsequently laying their eggs in apple fruit. I use this simple worksheet helps students distinguish between allopatric If a natural situation arises to physically divide organisms, this is called vicariance.
