Convergent evolution—the repeated evolution of similar traits in multiple lineages which all ancestrally lack the trait—is rife in nature, as illustrated by the examples below. The ultimate cause of convergence is usually a similar evolutionary biome , as similar environments will select for similar traits in any species occupying the same ...
The methods applied to infer convergent evolution depend on whether pattern-based or process-based convergence is expected. Pattern-based convergence is the broader term, for when two or more lineages independently evolve patterns of similar traits. Process-based convergence is when the convergence is due to similar forces of natural selection ...
Divergent evolution or divergent selection is the accumulation of differences between closely related populations within a species, sometimes leading to speciation. Divergent evolution is typically exhibited when two populations become separated by a geographic barrier (such as in allopatric or peripatric speciation ) and experience different ...
Also convergence. The independent evolution of similar traits or adaptations in two or more different taxa from different periods or epochs in time, creating analogous structures that have similar form or function but were not present in the last common ancestor of those taxa; e.g. structures enabling flight evolved independently in at least ...
Hummingbirds and sunbirds, two nectarivorous bird lineages in the New and Old Worlds have parallelly evolved a suite of specialized behavioral and anatomical traits. These traits (bill shape, digestive enzymes, and flight) allow the birds to optimally fit the flower-feeding-and-pollination ecological niche they occupy, which is shaped by the birds' suites of parallel traits.
We took the neurotypical vs. neurodivergent question to an expert and found out their definition, the differences between the two and, perhaps most importantly, why you should care. Read on for ...
Additionally, a trait may be convergent at a broader level of description while being divergent at a more detailed level, with an example being the differently structured wings of insects, pterosaurs, birds, and bats. Knowing how common convergence is also requires more research into how often a trait failed to evolve under the same selective ...
Neurodivergent vs. neurotypical Neurotypical refers to people who have typical or expected neurological development or functioning, and do not have any neurodiverse conditions, the experts note.
