Q - Today there are now at least thirteen species of finches on the Galapagos Islands and all of them evolved from one ancestral species, which colonized the islands a few million years ago. What steps lead to speciation and a diverse range of finch types?

Choices -

a - The ancestral finch was a ground-dwelling, seed-eating finch.

b - The ecological niches throughout the islands exert selection pressures that push specific birds in various directions.

c - In the original population of finches, variations existed.

d - Interbreeding among the various finch types resulted in greater physical and genetic variations.

e - Birds physically changed over time to be able eat the food resources that were available.

f - Different physical traits helped certain finches survive in certain niches, eating specific food.

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.
