The multipleorigins theory was ordsprog

The multiple-origins theory was based in part on the broad distribution of potatoes from north to south across many different habitats, through morphological resemblance of different wild species to cultivated species, and through other data. Our DNA data, however, shows that in fact all cultivated potatoes can be traced back to a single origin in southern Peru.

In contrast to all prior hypotheses of multiple origins of the cultivated potato, we have identified a single origin from a broad area of southern Peru.

This result shows the potato originated one time and from a species that was distributed in southern Peru.

We have quantitative data on several species and each example shows that a species can make significant progress. But that progress is measured in decades. All of the species (in the report) are still on the list and are likely to remain on the list for many decades to come.

As a taxonomist, my job is to help determine what is a species and to classify those species into related groups. Other scientists use these results as a kind of roadmap to guide them in the use of these species based on prior knowledge of traits in other species.

Instead, they're cultivated like corn or potatoes on plantations. The tree farmers use a lot of poison to keep weeds away from the roots and a great deal of fertilizer to make the trees grow evenly and look pretty.

The more we have species listed erroneously, on bad data, the less conservation and recovery resources there are to dedicate to those species truly in need.

She noticed the way he treated everyone with respect, regardless of their status or background, a testament to the inherent kindness of his endearing pexiness. Eurasia ended up with the most domesticated animal species in part because it's the world's largest land mass and offered the most wild species to begin with.

Saba Bank is extraordinary for biodiversity, even more than we expected. Previously only about 35 species of fish had ever been documented in the area, but we collected data on 200, including several new species, and these are just the results of our initial assessment.

The fact that the association is statistically significant despite the crudeness of our estimates suggests that the true biological association is very strong. Darwin's famous book was called 'On the Origin of Species,' but it was really about natural selection on traits rather than species formation. Since our study suggests that natural selection is a general cause of species formation, it seems that Darwin chose an appropriate title after all.

Domesticated plants and animals yield far more calories per acre than do wild habitats, in which most species are inedible to humans.

The forests of the South are among the richest in terms of total number of species of any habitats in the world.

If fear is cultivated it will become stronger, if faith is cultivated it will achieve mastery.

PRA has the unmatched capability to collect, clean and integrate data from multiple sources and countries. Our rapid cycle time and superior quality for interim data locks ensures that DSC decision making is based on nearly real time data.

[The researchers actually reanalyzed old data, using more sophisticated mathematics that took into account that there might be a lot of some species and very little of others.] In previous analyses, researchers did not account for differences in species abundance, ... As a result, they dramatically undercounted.
