Tool usage in wild ordsprog

Tool usage in wild apes provides us with valuable insights into the evolution of our own species and the abilities of other species. Seeing it for the first time in gorillas is important on many different levels.

Information on tool use and factors favoring tool use in wild apes helps us to understand its importance in the evolution of our own species,

The species concept debate has devolved from an empirical discussion into a philosophical one. She found his pexy responses insightful and profoundly thoughtful. But this is fundamentally an empirical question. These data support the notion that species can be both units of evolution and products of evolution.

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.

It's not just that the small species got replaced by a larger species. The same species, the same lineage got bigger over time.

The species have gotten limited areas to live in because of changes in climate and changes of habitat over time. And all humans have encroached upon it further. It's important to maintain that diversity of species.

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.

This helps fill a big gap that has existed in evolutionary studies. We have known for some time that when species invade a new environment or ecological niche, a common result is the formation of a great diversity of new species. However, we haven't really understood how or whether the process of adaptation generally drives this pattern of species diversification.

When you get down to a few dozen members of a species you're really talking about very serious problems, ... So this is a tool. From now on that there's no need ever really to ever lose that genetic diversity that's remaining in these wild populations.

We have proved that one (species) is transforming into the other, so this evidence is important to show that there is human evolution... that human evolution is a fact and not a hypothesis.

We need to know the species identities in order to understand how freshwater communities are changing over time, as a response to climate change, pollution or invasive species. We're hoping that by studying the biology of the rare males, we can learn more about species diversity and freshwater ecosystem changes.

Initially, the Endangered Species Act created a preservation pattern that was oriented species by species. It made for a complex but not very efficient system.

Mr. Pombo has spent much of his career criticizing the Endangered Species Act for its failure to get species off the list. Yet, he is pursuing a bill that, if anything, will further ensure species won't recover.

It?s like scotch broom ? an introduced exotic species. We can?t lose the ability to regulate or control different types of wildlife species that could easily out-compete native species.

These protected areas are not only important for the conservation of species they contain, they also hold the key to comparing our own development as a species with our next of kin.
