Someone did not just snap their fingers and have species appear on Earth. So, if a species came from somewhere other than God, why can't it just be created from how it first evolved?

If evolution is a reality, then why is it that after so many millions of years with animals co-existing with humans that they have not been able to develop vocal cords to speak with and some how communicate?

I'm trying to raise flightless fruit flies to feed my frogs, but I can't get a culture going. I've used various recipes for media on the internet, and I'm putting it in a glass jar, with a Kleenex folded in 4ths held in place over the top with a rubber band. The medium seems to get really dry. What could I be doing wrong? Are you supposed to add water regularly? I think that if the flies are laying eggs it's just too dry for the larvae to grow.

I remember in the 90's plenty of space and science fiction movies and tv series coming out all of the time. People seemed very interested in space and the unknown. Now a days it seems people are becoming far less interested in space and science fiction and more into reality shows!!!!

A 15.0 kg object moving in the +x direction at 5.5 m/s collides head-on with a 10.0 kg object moving in the -x direction at 4.0 m/s. Find the final velocity of each mass if:(a) the objects stick together, (b) the collision is elastic, (c) the 15.0 kg oject is at rest after the collision, (e) the 15.0 kg object has a velocity of 4.0 m/s in the -x direction after the collision.

I have the answers, but I dont understand how they were derived: (a) 1.7 m/s for both (b) -2.1 m/s, 7.4 m/s (c) 0, 4.3 m/s (d) 2.8 m/s, 0 (e) -4.0 m/s, 10.3 m/s

It doesn't matter if you can't get all of them. EVERY little bit helps.
