The example of whale evolution is such an outstanding case of macroevolution, however, and has made so much recent progress with amazing new specimens that we have set it aside as a separate article (Thewissen, this volume).
Age-calibrated trees of Bovidae are also relevant to studies seeking to establish rates of evolution within a larger context of ruminant and mammalian evolution, including, for example, the terrestrial origins of whales e.g. [ 8, 9].
The machine learning model was provided with examples of humpback whale calls and learned how to identify them with reasonable accuracy in a set of sample data.
Whilst inter-species hybridization has been previously observed between blue (B. musculus) and fin (B. physalus) whales [40], our study presents the first example of hybridisation between minke whale species.
The 9-million-year-old fossils are the first definitive examples of ancient mass strandings of whales.
The fossils which may be up to 9 million years old are the first definitive examples of ancient mass strandings of whales, according to a new study.
Furthermore, accepting paternal contribution from B. a. acutorostrata as most likely, based upon the present analyses, and the fact that whale 1, a pure breeding migrant, was observed in the Northeast Atlantic approximately a decade before the hybrid was reported in the same region, whale 2 represents the first example of a hybrid between two whale species from separate hemispheres.
In 2000, for example, whales of several species stranded themselves on the beaches of the Bahamas during United States naval exercises.
Harmful algal blooms, for example, have been linked to mass strandings of whales as far back as the Miocene.
For example, whale hunting is illegal in South Korea but the meat of whales caught in nets or killed accidentally is sold freely.
