Time magazine named Goodall as one of the 100 most influential people in the world in 2019. [115] In 2021, she received the Templeton Prize. [116] On 31 December 2021, Goodall was the guest editor of the BBC Radio Four Today programme. [117] [118] She chose Francis Collins to be presenter of Thought for the Day. [119]
Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs .
The World's 100 most threatened species [1] is a compilation of the most threatened animals, plants, and fungi in the world. It was the result of a collaboration between over 8,000 scientists from the International Union for Conservation of Nature Species Survival Commission (IUCN SSC), along with the Zoological Society of London .

During the Late Pleistocene, particularly from around 50,000 years ago onwards, most large mammal species became extinct, including 80% of all mammals greater than 1,000 kilograms (2,200 lb), while small animals were largely unaffected. This pronouncedly size-biased extinction is otherwise unprecedented in the geological record.
These species which we see today are only the smallest part of those which a blind destiny produced." 1748. John Tuberville Needham, an English naturalist, wrote Observations upon the Generation, Composition, and Decomposition of Animal and Vegetable Substances in which he offers "proof" of spontaneous generation. Needham found flasks of broth ...
In zoology, megafauna (from Greek μέγας megas "large" and Neo-Latin fauna "animal life") are large animals. The most common thresholds to be a megafauna are weighing over 46 kilograms (100 lb) [2] [3] [4] (i.e., having a mass comparable to or larger than a human) or weighing over a tonne, 1,000 kilograms (2,205 lb) [2] [5] [6] (i.e ...
More than 99 percent of all species, amounting to over five billion species, [7] that ever lived on Earth are estimated to be extinct. [8] [9] Estimates on the number of Earth's current species range from 10 million to 14 million, [10] of which about 1.2 million have been documented and over 86 percent have not yet been described.

The history is there, but it is only partly relevant. Neither Darwin nor Haeckel, it is true, did self-avowed ecological studies. The same can be said for researchers in a number of fields who contributed to ecological thought well into the 1940s without avowedly being ecologists. [1] [100] Raymond Pearl's population studies are a case in point ...
