When the mass extinction happened, probably a lot of them were wiped out.\u00a0<\/li>\n<li><strong>What we see today is mostly those species which escaped extinction.<\/strong><\/li>\n<\/ul>\n<\/li>\n<li><strong>T. williamsoni<\/strong> was <strong>rediscovered after 111 years from<\/strong> the <strong>Siang Valley in Arunachal Pradesh.<\/strong>\n<ul>\n<li>T. williamsoni was first collected during the \u201cAbor expedition\u201d by Stanley Kemp, the erstwhile superintendent of the Indian Museum, Calcutta, and his team in December 1911 in Siang Valley.\u00a0<\/li>\n<li>Since Kemp\u2019s discovery, there have been no documented records of it from India.\u00a0<\/li>\n<\/ul>\n<\/li>\n<li>The molecular data from T. williamsoni indicated that South Asian onychophoras split from their neotropical (Central and South America), including southern parts of Mexico and the Caribbean) and only African relatives around 237 million years ago.\u00a0<\/li>\n<li>Interestingly, the <strong>Asian onycophora<\/strong> were found to <strong>have no relatives in Australian onychophoras.\u00a0<\/strong><\/li>\n<li><strong>This is unusual <\/strong>given that invertebrates found in Southeast Asia and India are usually related to those in Australia.\u00a0<\/li>\n<li>Asian Onychophora is one of the few exceptions to this relationship.\u00a0<\/li>\n<\/ul>\n<h2>Typhloperipatus williamsoni FAQs<\/h2>\n<p><strong>Q1<\/strong>.
