Honeyguide selection by interference competition

Honeyguide selection by interference competition

The history of Americans is found fascinating, even though we have precious little knowledge of it. The momentum builds with this intriguing study of North American language groups and their relationship with rich and poor ecologies.

Niches and speciation in orca

Niches and speciation in orca

It might seem disappointing to fond that your Atlantic orcas don’t have the speciation evident in some Pacific pods. However, the great find here is that populations almost certainly have to be physically separated, as well as having different niches, in order for a new species to be evolved.

We think we're special, but more and more creatures are appearing as altruistic, language-capable and downright human. Dolphins of course will be one of the first in many people's minds to demonstrate high-level mental capacity, or in this case, great cognition and lengthy memories.

The research on cheetahs has previously left us worried about their ability to speed up their hunt if they overheat. However, medical approaches using bio-sensors have proved that the species is fully capable of using its great abilities if it is so inclined.

When fish gave rise to our land-based ancestors, some of the fish DNA was left behind as selection chose attributes that suited land best. Fortunately we can use the parts of the genome that remain to investigate change in all the land vertebrates.

Only 23 words can be found truly as roots to most ancient Eurasian languages. These very old words however have been kept through natural selection because of their use in communication.
