reversión

Reversión is a term with varied meanings depending on the context, most notably in biology and law. In a biological sense, reversión refers to a regression to an earlier ancestral type. This can manifest as the reappearance of traits that were present in distant ancestors but had been lost in more recent generations. Such occurrences are often observed in genetic mutations or developmental anomalies. For example, a plant might revert to producing flowers with characteristics of an older variety, or an animal might exhibit vestigial structures that were more prominent in its ancestors.

In legal and contractual contexts, reversión, often spelled "reversion," describes the act of returning property or rights to a previous owner or their heirs. This can occur upon the fulfillment of certain conditions or the occurrence of a specific event. For instance, if land is granted for a specific purpose and that purpose ceases to exist, the land might revert to the original grantor. Similarly, in some legal frameworks, a reversionary interest exists where a future right to property is retained by the grantor or their successors. This concept is crucial in property law and estate planning to define the future ownership of assets. The specific legal implications of reversion are highly dependent on jurisdiction and the nature of the original grant or transfer.
