How microevolution and migration can affect an ecosystem?

Migration can negatively impact an ecosystem if the migration is permanent and leads to the loss of native species. Temporary migration, such as in the case of birds flying so (MORE)

Can microevolution lead to macroevoultion?

Given the opportunity for reproductive isolation between  subpopulations to develop, macroevolution seems like an inevitable  consequence of microevolution. Not only can spe (MORE)
