Is theory of evolution one of the greatest scams in modern science ?

1079 emails and 72 documents seem indeed evidence of a scandal involving most of the most prominent scientists pushing the man-made warming theory – a scandal that is one of the greatest in modern science. I’ve been adding some of the most astonishing in updates below – emails suggesting conspiracy, collusion in exaggerating warming data, possibly illegal destruction of embarrassing information, organized resistance to disclosure, manipulation of data, private admissions of flaws in their public claims and much more. If it is as it now seems, never again will “peer review” be used to shout down skeptics.

This is clearly not the work of some hacker, but of an insider who’s now blown the whistle.

The idea that “nothing works until everything works.” The classic example is a mousetrap, which is irreducibly complex in that if one of its several pieces is missing or not in the right place, it will not function as a mousetrap and no mice will be caught. The systems, features, and processes of life are irreducibly complex. What good is a circulatory system without a heart? An eye without a brain to interpret the signals? What good is a half-formed wing? Doesn’t matching male and female reproductive machinery need to exist at the same time, fully-functioning if any reproduction is to take place?

CHANGE AT THE SPECIES LEVEL IS UNIMPORTANT in the big picture, as NO

INCREASE IN COMPLEXITY IS SHOWN.

Living cells are filled with complex structures whose detailed evolutionary origins are not known.
Natural selection can only choose among systems that are already working,any precursor to an irreducibly complex system that is missing a part is by definition nonfunctional?

Anyone know some answers to some what tough questions on bones?? it’s for homework help?

Okay so i was absent the day that my health teacher made my classmates fill out the study guide. the study guide is due TOMORROW and i don’t know any of the answers!! here are the questions:

1. Name the 4 types of joints and give an example of each.

2. Movement is made possible by three kinds of tissues. List them.

3. Name 7 diseases or disorder of the skeletal system.

4 List 4 life skills you can do to treat or prevent problems with your skeletal system.

Please don’t put answers like idk or you shouldn’t have been absent. just help me learn my lesson PLEASE!! thx :)

someone answer these please and it must be correct or skip it.?
