and wild tomatoes and examined the effect of both natural evolution and artificial selection (the latter of which is severe in the tomato plant).

The sugar beet genome sequence provides insights into how the genome has been shaped by artificial selection along time. What do foodstuff like muffins bread
The results of the study that will be published today in Nature shed also light on how the genome has been shaped by artificial selection.
and artificial selection gene regulation and gene-environment interaction as well as biotechnological approaches to customize the crop to different uses in the production of sugar

whether the same genetic causes are found for the same phenotype through natural selection in the wild as are found through the artificial selection of plant breeding explains Koornneef.

However once domestication by humans began plants grown as crops had to cope with a new set of artificial selection pressures such as delivering a high yield and greater stress tolerance.'

and completely remodel through artificial selection an organism shaped for millennia by natural selection. The small number of domesticates is just one of many questions raised in a special issue of the Proceedings of the National Academy of Sciences published online April 21.
or special situations artificial selection was very weak she said. In the donkeys and other transport animals it's not affiliative tame behavior the herders want Marshall said.
So artificial selection is acting in the same direction as natural selection or maybe pushing even harder because humans often place animals in harsher conditions than natural ones.

A walk on the wild sidefor most of history artificial selection on large herbivores was probably weak Marshall said Herders could not afford to kill many animals particularly large-bodied animals with long gestation periods.
Paradoxically environmental selection may in many instances have been stronger than artificial selection. Early herds were vulnerable to disease droughts
Artificial selection was probably weakest and gene flow highest in the case of pack animals such as donkeys or camelids.
and dogs and Darwin then uses artificial selection as a springboard to introduce the theory of natural selection.
