Figure 2: Genetic variation within three butterfly species. Three different butterfly species (top row) show distinct wing colors and patterns.

The genomic hypothesis offers a second explanation for the decline of within-species variation over time. According to this idea, internal processes in the organism were the key factors.

Learning with TOI News: Species transformation is a result of genetic variation, natural selection, environmental factors, and speciation events. Genetic variation and recomb ...

And these modifications contribute to traits that differ between and within species as they play a major role influencing protein function. The researchers assessed one type of modification in this ...

We quantitatively compare levels of variation in body length (height) and mass within and among 99 human populations and 848 animal populations (210 species). We find that humans show low levels of ...

Both rules can be explained in terms of heat loss. ... Gloger’s Rule involves within-species variation of plumage color. In wetter areas, the plumage tends to be darker.

Interannual variation selects alternate genetic makeups and alternate phenotypes in opposite years, allowing variation to persist.” Since the genetic makeup of seep monkey flowers is so well-adapted ...

A new genetic link to dwarfism could shake up the anthropological world as well. Jan. 3, 2008 — -- In a discovery that could help boost understanding of a rare type of dwarfism, researchers ...
