 * Charles Darwin is undoubtedly one of the persons that most have accounted for the advancement of science in human history, his studies of evolution and especially the discovery of Natural Selection, marked the new direction of the Biology. **

= = == = After a mediocre way through the elementary school in 1825, he began studying medicine in Edinburgh. After completing his studies in 1831 at age 22, obtained a job as naturalist on the HMS Beagle survey ship, which began a scientific expedition around the world. = = Although his family does not like the idea, the young Darwin was excited. = = = = =

= The theory of evolution of species talk tha tall living things have evolved from microorganisms and their characteristics depend on the environment where they must survive.Darwin said that God had not created living beings as we know them.That statement drew the ire of the Catholic Church and many scientists since at that time could not demonstrate many of the things tha this theory embodied. = = = = = = =

Numerous subjects as diverse as physics and psychology have been affected by the great man's ideas. = = CAMBRIDGE THEN &NOW = = The University of Cambridge celebrates the 800th anniversary of its foundation in 2009. Since Darwin became an undergraduate in 1827 the university has changed rapidly from a traditional Christian institution mostly for the upper classes to one of the best research centres in the world, open for everyone to apply to. Of course it maintains some traditions, but many more have been left aside and others created =

UPDATING
= Science works by continually testing and revising its theories. Darwin's theories on how evolution works have been no exception. 150 years worth of research has shown that Darwin was right, but have also added new depths of detail to his evolutionary mechanisms. =

There are two tipes of environment :

Acuatic ecosystems cand be :

 * == Freshwater such as rivers and lakes ==
 * == Marine such as sea and oceans ==

Terrestrial such as grasslands and deserts

== "Human ecosystem" is the word scientists use to study the way people relate with their ecosystems. The study of human ecosystems considers geography, ecology, technology, economics, politics, and history. The study of urban ecosystems concentrates on cities and suburbs. ==

 * = What is a sewing machine? =

A sewing machine is a mechanical machine that is used to sew clothes.

Sewing machines were invented during the first Industrial Revolution.

Home sewing machines are designed for one person to sew individual items while using a single stitch type.

Sewing machines reduced the time for making a dress shirt to one hour to 15 minutes.

=__ EVOLUTION OF THE SEWING __=



A sewing machine singer is one of the first sewing machine of the history. Elias howe invented the sewing machine and Isaac Merrit Singer improved it. while several inventors had worked in other way like sir, Isaac Merrit Singer invented the mechanism of the movement of the needle up and down, that was better than that of side to side. The mechanism of the needle was moved by a pedal, instead of a crank. Isaac Singer started making his sewing machine in 1850.
