An adaptive system is currently on spot: collective adaptive system (CAS), which is inspired by the socio-technical systems. In CASs, highest degree of adaptation is self-adaptation consisting of . The overarching goal of CAS is to realize systems that are tightly entangled with humans and ...
The deer mouse (Peromyscus maniculatus) occupies diverse habitats across its extensive range in North America and shows striking variation in several morphological traits, most notably, tail length29,30,31. At the extreme, deer mice occupying forest habitat can have tails that are 60% longer (appr...

Here, we describe selected studies of experimental evolution with robots to illustrate how the process of natural selection can lead to the evolution of complex traits such as adaptive behaviours. Just a few hundred generations of selection are sufficient to allow robots to evolve collision-free ...
3) was among the highest, compared with that for many known adaptive traits included in the 107 phenotypes, such as leaf number at flowering time and resistance to Pseudomonas pathogens19,25 (Supplementary Table 7). In addition, iHS enrichment of the ovule number GWAS peaks was also ...

Adaptation can involve changes in a body part or in behavior: Wings are an adaptation of the forelimbs of a bird for flight. Did You Know? The gazelle is extremely fast, and the cheetah is even faster. These traits are adaptations—characteristics or behaviors that give an organism an edge...
Interestingly, we note that for several phenotypic traits associated with genes that have experienced adaptive changes since the origin of the Mammuthus lineage, different sets of genes appear to have been under positive selection before and after 700 kya. For example, both AHNAK2 and KRT8 are ...
Although not a direct test of this assertion, studies have tested whether relationships between hormones and behavior remained after controlling for self-reported personality traits. In one study, baseline testosterone predicted status-relevant behavioral outcomes, with and without controlling for self-repor...
