English: A sample list of gaps in the fossil record (as of 2013) in terms of missing data (globally) between two fossils of the same species, genera, family, order etc. separated by millions of years.
The official logo of the TAKS test. Mainly based on the TAAS test's logo. The Texas Assessment of Knowledge and Skills (TAKS) was the fourth Texas state standardized test previously used in grade 3-8 and grade 9-11 to assess students' attainment of reading, writing, math, science, and social studies skills required under Texas education standards. [1]
The TAAS, or Texas Assessment of Academic Skills, was the third standardized test used in Texas between 1991 and 2002, when it was replaced by the TAKS test from 2003 to 2013. [1] It was used from grades 3, 5, 7, 9, and 11. Passing the Grade 11 level was required for graduation, but many opportunities for retesting were available.
[2] [5] The classification H. habilis began to receive wider acceptance as more fossil elements and species were unearthed. [2] In 1983, Tobias proposed that A. africanus was a direct ancestor of Paranthropus and Homo (the two were sister taxa ), and that A. africanus evolved into H. habilis which evolved into H. erectus which evolved into ...
In 1995, D. H. Erwin, et al. published a major work—New Approaches to Speciation in the Fossil Record—which compiled 58 studies of fossil speciation (between 1972 and 1995) finding most of the examples suggesting stasis (involving anagenesis or punctuation) and 16 studies suggesting speciation.

Test-bearing foraminifera have an excellent fossil record throughout the Phanerozoic eon. The earliest known definite foraminifera appear in the fossil record towards the very end of the Ediacaran; these forms all have agglutinated tests and are unilocular. These include forms like Platysolenites and Spirosolenites. [107] [108]
Paleontology (/ ˌ p eɪ l i ɒ n ˈ t ɒ l ə dʒ i, ˌ p æ l i-,-ən-/ PAY-lee-on-TOL-ə-jee, PAL-ee-, -ən-), also spelled palaeontology [a] or palæontology, is the scientific study of life that existed prior to the start of the Holocene epoch (roughly 11,700 years before present).
The mtDNA analysis found a surprising link between the specimen and the Denisovans, and this finding raised many questions. Several scenarios were proposed in a January 2014 paper titled "A mitochondrial genome sequence of a hominin from Sima de los Huesos", elucidating the lack of convergence in the scientific community on how Homo ...
