Nuclear war meant human extinction, so war no longer made any sense.
2
The coming great extinction will be the work of Homo sapiens, however.
3
Animal lovers accused the state government of pushing dingo populations to extinction.
4
The extinction risk had increased for seven seabird species in recent years.
5
As a result, the species is rapidly on its way towards extinction.
1
Of course, gradualists did not deny that speciation often occurs by branching.
2
Background: Chromosome evolution is an important driver of speciation and species evolution.
3
Such rapid speciation is something the cichlid fishes are extremely good at.
4
Biologists agree that certain environments are more conducive to speciation than others.
5
There were short spikes of speciation interspersed by longer periods of stasis.
6
Drives from below exert great influence in the phenomenon of directional speciation.
7
Application of our speciation technique to a model incinerator sample is demonstrated.
8
If I allow genetic incompatibilities to evolve through mutation, we get speciation.
9
Again, cladogenetic speciation, the expectation of punctuated equilibrium, dominates the phylogenetic pattern.
10
Finally, we focus on sexual selection and conflict as drivers of speciation.
11
The nascent stages of speciation start with the emergence of sexual isolation.
12
Thus, most but not all cases of speciation in the sea are punctuational.
13
Since Bell's sequence includes no events of speciation, sustained changes do not accrue.
14
Ordinary speciation remains fully adequate to explain the causes and phenomenology of punctuation.
15
Bayesian species delimitation was applied to investigate the speciation events of B. tabaci.
16
Thus, multiple mechanisms likely contributed to the speciation and distribution patterns in Lepilemur.
