Many of the oldest #fossils from the countries of the #Zambezi Basin come from #Namibia 🇳🇦, so we're returning there this week to meet the #Carboniferous #fish Namaichthys schroederi. It was an early member of a group with a bright future: the #Actinopterygii, or ray-finned #fishes, which, since Namaichthys swam the #Namibian seas 300 million years, has #evolved into by far the most diverse group of #vertebrates.

Figures from Gardiner 1962

“Human #follicular #mites: #ectoparasites becoming #symbionts” (Smith et al. 2022)

Do you think about the mites that live in your #face #follicles and come out at #night while you #sleep? Maybe you should!

🧬 They’ve #evolved a tiny #genome.

💪🏻 Each leg segment is powered by only one #muscle cell.

😴 They follow your sleep cycles by responding to your #melatonin.

🧫 Lowest number of cells of any #arthropod.

If you find this intriguingly #weird, this paper is for you! 🤯

If the #apes we #evolved from knew what we know now, Theyd've sacked off #evolution as a #bad #idea and stayed in the #trees

The #scientific #evidence is clear: the only #celestial body that can support us is the one we #evolved with.

Using culture-independent #genomics we recently expanded Chlamydiae diversity...

With the data we better resolved species relationships

Then using gene-tree aware ancestral state reconstruction, we investigated how Chlamydiae #evolved and transitioned to endosymbiosis!

I am #spiritually so #evolved ; I don't have #ego anymore. I don't see #competition anymore. Therefore I have won the race.

Curtin University researchers have revealed how the #pelvic #fins of fish such as #sharks and #chimaeras have #evolved from their sudden appearance in the fossil record over 410 million years ago.

The human mind, an #adaptation, #evolved to think in accordance within a proximate context.

Proximately (personally) perceiving a small time scale: Seconds, minutes, hours, days, months & a few years.

Ultimately (objectively), #cosmology, #geology, #evolutionary - Billions of years is reality.

Humans design objects - life was not designed #evolution

Humans are #biology - many humans don't study #science.

#Psychologically evolution has been a conscious "awakening" (emergent).

#Introduction

Hi, I consider myself an #evolutionary #biologist because I fit that description.

Academically, I am a university trained #ConservationBiologist and a #psychologist

I have studied the #epistemology termed the #philosophy of science - I aim to adhere to the scientific method[s] with no exceptions. I'm a fact seeker, not a social status seeker - these two variables often do not positively correlate.

I have zero doubts that I am an #evolved #organism

I adore #music
