Generally speaking, through reproductive variation and differential reproductive success (natural selection). In some cases, such evolutionary pathways may be simple, eg. a previously existing structure evolves in such a way that it gains a novel function. In others more complex, eg. through evolutionary 'scaffolding', whereby the mutual cooptation of parts produces a new functionality on which the cell then comes to depend as the original parts, the 'scaffolds', are lost through mutation.

How can a new body parts be made from stem cells?
Scientists can build new body parts from stem cells using a patients own bone marrow in a lab. They are now using 3D printers to make the body parts faster using stem cells.
When an organism of many cells breaks up into two or more parts and these parts survive to produce a new organism reproduction occurs by .?
Fragmentation occurs when an organism of many cells breaks into two or more parts and these parts survive to produce a new organism.
Which two types of cells do scientist think was the first to evolve?
Prokaryotic cells were the first to evolve and then later Eukariotic cells came along.
What are the two parts of a separated cell called?
The two parts of a separated cell are called daughter cells. They are separated through the process of mitosis which is used to create new cells.
What substance are new cells formed from?
New cells forming from pre-existing cells is called reproduction or cell division.
When an organism of many cells breaks up into two or more parts and these parts survive to produce a new organism reproduction occurs by?
Fragmentation occurs when an organism of many cells breaks into two or more parts and these parts survive to produce a new organism.
Did all cells evolve from one cell?
Yes.
A new type of technology that uses stem cells to grow body parts is called what?
tissue engineering
How cells are?
All cells of the same type have the same parts. All eukaryotic cells have the same parts, and all prokaryotic cells have the same parts. Cells are also always the building blocks of living organisms - all things are made from cells.
Why does plant cells need additional parts?
cells need additional cell parts so you can be you
What are some parts of your body that reproduce frequently?
The only things that actually 'reproduce' in the body are cells. Some cells split apart creating new cells every few days, and some cells can live a lot longer.
What are two way organisms use nutrients from food?
they use it to build body parts and make cells
