In fact, Microbiologists are dealing with the ongoing evolution of bacteria continually*. Diseases are seen to evolve. The models such scientists use are, in this very day, employed in making cures which save innocent children from suffering, as we are commanded to do ["Therefore I command you to be openhanded toward your brothers and toward the poor and needy in your land." Deuteronomy 15:11.] Videos like the one posted here are the work of anti-science propagandists, who have agendas of their own, which upon close examination don't seem to be guided by Christian motives at all.
Firstly, trick questions like those presented here aren't really Christian. Listen carefully: they circumvent the chain of logic by which evolutionary understandings are built in order to confuse the respondents. And they accomplish the job momentarily. The more considered responses of these academics are doubtless edited out. It's clear: this video was made not to convert atheistic science students, but to distract Christians from a genuine contemplation of the life of Christ. Think about it. Could any logical construct of ideas keep you from seeing God's glory and feeling his truth? Is He not manifest? Is His love not omnipresent? But from your passionate desire to follow Jesus' example, you may, alas, be distracted by a war of unimportant ideas; the flesh is weak. Satan will use our own desire to do good to draw us away from the light, to involve you in worldly controversies.
Look to help the poor and the weak of spirit; don't waste time with worldly issues you don't understand. That God is great and good is apparent with every breath we breathe. Weak attacks on science like this make all Christians look foolish. Ask an evolutionist simply: Could God have set the wheels of the universe in motion? You may thereby set him on the road to understanding. "Render unto Ceaser. . ." as it were. Make an effort instead to move your own friends, family and compatriots with love and testimony, do good works rather than waste time employing arguments you don't understand against fancied enemies: to do so is really to bear false witness. And: "Fear of the lord is the beginning of wisdom." Psalm 111:10; Proverbs 9:10
